Where does mucus come from when you cough. The Origins and Functions of Mucus: A Comprehensive Guide to Your Body’s Natural Defense Mechanism

Where does mucus come from when you cough. How does the body produce mucus. What are the main components of mucus. Why is mucus essential for our health. How does mucus protect our organs. What causes excessive mucus production. When should you be concerned about mucus buildup.

The Fascinating World of Mucus: An Often Overlooked Bodily Fluid

Mucus, a substance often associated with illness, plays a crucial role in maintaining our health. This slippery, gel-like fluid is continuously produced by our bodies, serving as a protective barrier and a key component of our immune system. But where exactly does mucus come from, especially when we cough?

The human body is a marvel of biological engineering, with mucus production being one of its many intricate processes. Glands located in various parts of our body, including the eyes, mouth, nose, sinuses, lungs, throat, stomach, intestines, and reproductive organs, are responsible for producing mucus. On average, a healthy person secretes between 1 to 2 quarts of mucus daily, most of which goes unnoticed as it performs its vital functions.

The Composition of Mucus: More Than Just Water

While mucus may seem like a simple substance, its composition is quite complex. The main components of mucus include:

  • Water (the primary ingredient)
  • Mucin (a gel-forming molecule)
  • Antimicrobial molecules
  • Immune-modulating molecules
  • Protective molecules
  • Various proteins and sugars

This unique composition allows mucus to perform its multifaceted role in our body’s defense system.

The Vital Functions of Mucus in Our Body

Mucus is far more than just a nuisance during cold and flu season. It plays several critical roles in maintaining our health and well-being:

  1. Moisturizing inhaled air
  2. Preventing moist organs from drying out
  3. Filtering, trapping, and eliminating inhaled particles and microorganisms
  4. Fighting infections
  5. Protecting tissues

These functions highlight the importance of mucus in our daily lives, even when we’re not aware of its presence.

Mucus as a Natural Air Filter

One of the most crucial roles of mucus is its function as a natural air filter. As we breathe, mucus in our respiratory system traps allergens, dust, smoke, pollution, viruses, bacteria, and fungi. This process prevents these potentially harmful substances from entering deeper into our lungs and causing damage.

The Journey of Mucus: From Production to Elimination

The life cycle of mucus is a fascinating process that involves various organs and bodily systems. But how does mucus travel through our body?

Once mucus has trapped particles in the lungs, tiny hair-like structures called cilia come into play. These cilia beat in unison, creating a wave-like motion that pushes the mucus, along with its trapped particles, up and out of the lungs. This mucus then typically moves down the throat without us noticing.

From the throat, the mucus continues its journey to the stomach. Here, it’s digested along with other contents and eventually eliminated from the body through feces or urine. In some cases, particularly when we’re sick or experiencing allergies, we may cough up mucus and expel it through the mouth.

The Cellular Machinery Behind Mucus Production

The production of mucus is a complex process involving several types of specialized cells. The main players in this biological drama are:

  • Goblet cells: These are the primary producers of mucin, the gel-forming molecule that gives mucus its characteristic consistency.
  • Ciliated cells: These cells are covered with tiny hair-like projections (cilia) that help move mucus through the body.
  • Submucosal glands: Found in the airways, mouth, and gastrointestinal tract, these glands also produce and release mucin and mucus.

Together, these cellular components work tirelessly to ensure a constant supply of this vital bodily fluid.

When Mucus Production Goes into Overdrive: Causes and Consequences

While mucus production is generally a beneficial process, certain conditions can lead to excessive mucus production or accumulation. What triggers this overproduction?

  • Infections (bacterial, viral, or fungal)
  • Allergic reactions
  • Exposure to irritants (pollution, smoke, dust)
  • Certain medical conditions (asthma, COPD, cystic fibrosis)
  • Hormonal changes
  • Some medications

When the body produces too much mucus or the mucus becomes too thick, it can lead to congestion, difficulty breathing, and increased susceptibility to infections.

The Role of Inflammation in Mucus Production

Inflammation plays a significant role in mucus overproduction. During an infection or allergic reaction, inflammatory processes can cause the tissues lining the airways to swell. This swelling stimulates the submucosal glands to produce more mucus. Additionally, the mucus often becomes thicker as it fills with immune cells and trapped foreign particles, further exacerbating the problem.

Mucus in Health and Disease: When to Be Concerned

While mucus production is a normal and necessary bodily function, changes in the amount, color, or consistency of mucus can sometimes indicate an underlying health issue. When should you be concerned about your mucus?

  • Persistent increase in mucus production
  • Changes in mucus color (especially green or yellow)
  • Blood in the mucus
  • Thick, sticky mucus that’s difficult to expel
  • Mucus accompanied by other symptoms like fever, chest pain, or difficulty breathing

If you experience any of these symptoms, it’s advisable to consult with a healthcare professional for proper evaluation and treatment.

Managing Mucus: Tips and Techniques

While we can’t (and shouldn’t) stop mucus production entirely, there are ways to manage excessive mucus and alleviate associated symptoms. Here are some strategies that can help:

  1. Stay hydrated: Drinking plenty of water can help thin mucus, making it easier to expel.
  2. Use a humidifier: Adding moisture to the air can prevent mucus from becoming too thick.
  3. Try saline nasal sprays: These can help flush out excess mucus and irritants.
  4. Elevate your head while sleeping: This can prevent mucus from pooling in your throat.
  5. Avoid irritants: Steer clear of smoke, strong fragrances, and other known triggers.
  6. Practice good hygiene: Regular hand-washing can help prevent infections that lead to increased mucus production.

Remember, these are general tips and may not be suitable for everyone. Always consult with a healthcare provider for personalized advice.

The Role of Diet in Mucus Management

While the relationship between diet and mucus production is still a subject of ongoing research, some people report that certain foods affect their mucus levels. Foods that are commonly believed to increase mucus production include:

  • Dairy products
  • Wheat and gluten-containing foods
  • Processed foods high in preservatives
  • Sugary foods and beverages

On the other hand, some foods are thought to help reduce mucus or its symptoms:

  • Ginger and turmeric (for their anti-inflammatory properties)
  • Citrus fruits (rich in vitamin C)
  • Garlic and onions (for their antimicrobial properties)
  • Leafy green vegetables (high in antioxidants)

It’s important to note that dietary effects on mucus can vary greatly between individuals. If you suspect certain foods are affecting your mucus production, consider keeping a food diary and discussing your observations with a healthcare provider or registered dietitian.

The Future of Mucus Research: Potential Medical Applications

As our understanding of mucus and its properties grows, researchers are exploring potential medical applications for this versatile bodily fluid. Some areas of ongoing research include:

  • Developing artificial mucus for therapeutic purposes
  • Using mucus properties to enhance drug delivery systems
  • Studying mucus to improve treatments for conditions like cystic fibrosis and COPD
  • Investigating the role of mucus in the gut microbiome and its impact on overall health

These exciting developments highlight the growing recognition of mucus as a crucial component of our body’s defense system and its potential in advancing medical treatments.

The Mucus Microbiome: A New Frontier in Health Research

Recent studies have revealed that mucus is not just a passive barrier, but a complex ecosystem teeming with microorganisms. This “mucus microbiome” plays a crucial role in maintaining our health and protecting us from pathogens. Researchers are now investigating how changes in the mucus microbiome might be linked to various health conditions and how we might be able to manipulate this ecosystem for therapeutic purposes.

The study of the mucus microbiome opens up new possibilities for understanding and treating a wide range of health issues, from respiratory conditions to gastrointestinal disorders. As this field of research progresses, we may see the development of novel therapies that target the mucus microbiome to promote health and fight disease.

Mucus Through the Ages: Historical Perspectives and Cultural Significance

While modern science has given us a deep understanding of mucus and its functions, this bodily fluid has been a subject of interest and speculation throughout human history. How has our perception of mucus evolved over time?

In ancient medical traditions, such as Traditional Chinese Medicine and Ayurveda, mucus (often referred to as “phlegm”) was considered one of the vital humors that needed to be in balance for good health. These traditions developed various remedies and practices aimed at managing mucus, many of which are still used in complementary medicine today.

In Western medicine, the understanding of mucus has evolved significantly over the centuries. From being viewed as a sign of illness or imbalance in the humoral theory of medicine, to being recognized as a crucial component of our immune system in modern times, our perception of mucus has come a long way.

Cultural Attitudes Towards Mucus

Cultural attitudes towards mucus vary widely around the world. In some cultures, the act of expelling mucus is considered highly taboo and is only done in private. In others, it’s seen as a normal and necessary bodily function that doesn’t require much discretion.

These cultural differences can have real-world implications, especially in healthcare settings where misunderstandings about mucus-related behaviors can lead to communication breakdowns between patients and healthcare providers.

Understanding these cultural perspectives is crucial for healthcare professionals working in diverse communities and for anyone navigating cross-cultural interactions.

Mucus in the Animal Kingdom: Diversity and Adaptation

Humans aren’t the only creatures that produce mucus. In fact, mucus production is widespread in the animal kingdom, with many species using it in fascinating and diverse ways. How do other animals use mucus?

  • Slugs and snails use mucus for locomotion and protection
  • Fish produce mucus as a protective coating for their scales and gills
  • Some frogs secrete mucus with antibiotic properties
  • Hagfish produce large quantities of slime (a form of mucus) as a defense mechanism

Studying mucus production and use in different species not only enhances our understanding of animal biology but also provides insights that could lead to biomimetic innovations in fields like medicine and materials science.

Mucus-Inspired Technologies

The unique properties of mucus have inspired various technological innovations. For example:

  • Researchers are developing mucus-inspired materials for use in protective coatings and lubricants
  • The adhesive properties of slug mucus have inspired new types of surgical glues
  • The filtering capabilities of mucus are being studied to improve air and water purification systems

These examples demonstrate how understanding mucus can lead to practical applications that extend far beyond medicine and biology.

As we continue to unravel the mysteries of mucus, from its intricate production process to its diverse functions across species, we gain a deeper appreciation for this often-overlooked substance. Far from being merely a nuisance during times of illness, mucus proves to be a fascinating and essential component of life, playing crucial roles in health, disease, and potentially, future technological innovations.

Where does mucus come from?

The body uses mucus to protect tissues, remove particles, and prevent infections. Mucus consists mainly of water and a gel-forming molecule called mucin. It also contains antimicrobial and other molecules.

Mucus is essential for the functioning of many of the body’s organs. A person might think their body only makes mucus in response to illness, allergens, or irritants. But the body is always producing mucus, which is crucial for the functioning of several organs and the immune system.

Many health issues can lead to a buildup of mucus, drawing a person’s attention to this key bodily fluid. Most healthy people never notice that they are continually producing and swallowing it.

Below, learn what mucus is, how it forms, and what causes a buildup. We also explore tips for clearing it and when to contact a doctor.

Mucus is a fluid that the body produces to line moist areas, such as the:

  • eyes
  • mouth
  • nose
  • sinuses
  • lungs
  • throat
  • stomach
  • intestines
  • reproductive organs

Most people only notice mucus when they are ill or exposed to allergens or irritants in the air. But glands in the areas listed above make mucus continually, secreting around 1–2 quarts daily.

Mucus helps with crucial functions, such as:

  • adding moisture to inhaled air
  • preventing moist organs from drying out
  • filtering, trapping, and eliminating inhaled microparticles or microorganisms, such as allergens, dust, smoke, pollution, viruses, bacteria, and fungi
  • fighting infection

Mucus helps trap microorganisms and microparticles on the surface of the lungs. Tiny hair-like appendages that line the lungs, called cilia, then beat in unison, creating a pulse that moves the entrapped particles up and out of the lungs.

Once the particle-filled mucus reaches the back of the throat, it typically moves down the throat without the person noticing.

After traveling down the throat, the mucus reaches the stomach, where it is digested and eliminated from the body in feces or urine. Mucus in the throat can also be coughed up and spit out.

Mucus is mostly made of water, but it also contains important proteins and sugars. The cells that make mucus also produce molecules that support immune function, and these become incorporated into the mucus.

The molecules in mucus include:

  • antimicrobial molecules
  • immune-modulating molecules
  • protective molecules

The tissues lining the airways, nose, sinuses, and mouth contain two primary cell types: secretory cells, which release the components of mucus, and ciliated cells. These are covered with tiny hair-like projections called cilia.

Mucus is mostly water and a gel-forming molecule called mucin.

Special secretory cells called goblet cells are the predominant producers and releasers of mucin. A goblet cell is shaped like a medieval goblet, and it is not covered with cilia.

Goblet cells and other secretory cells also release a range of proteins, salts, fats, and immune molecules that mix with mucin and are incorporated into mucus.

Submucosal glands, found in the airways, mouth, and gastrointestinal tract, also produce and release mucin and mucus.

Ciliated cells use their tiny projections to move mucus throughout the body. The cilia move in a way that creates a unified pulse, pushing mucus along in waves.

Infections and irritants

When the airways are exposed to irritants, goblet cells and submucosal glands produce extra mucus to clear the airways.

In addition, infections can cause inflammation in airway tissues, which can likewise trigger the submucosal glands to produce more mucus. During an infection, mucus thickens because it fills with immune cells and entrapped foreign particles.

Allergic reactions occur when the immune system responds excessively to a harmless substance. The reaction triggers the release of histamine — a compound that can cause the airway linings to swell and stimulate the submucosal glands to produce more mucus.

Most healthy people are unaware that they are continually producing and swallowing mucus.

Several health issues can cause mucus to build up, either by stimulating excessive production, blocking or reducing mucus elimination, or causing the mucus to thicken.

Factors associated with mucus buildups include:

  • allergies, especially to dairy
  • bacterial, viral, or fungal infections
  • breathing in very cold or dry air
  • inhaling irritating particles such as pollution, smoke, dust, dander, or mold spores
  • hormonal changes that occur with aging
  • certain medications that can thicken mucus, including birth control pills and high blood pressure medications
  • gastroesophageal reflux
  • pregnancy
  • asthma
  • vasomotor rhinitis, having an extra-sensitive nose
  • nasal growth or polyps
  • irregular nasal cartilage structure
  • cystic fibrosis
  • non–cystic fibrosis bronchiectasis and panbronchiolitis
  • chronic obstructive pulmonary disease, commonly called COPD
  • primary ciliary dyskinesia
  • hypogammaglobulinemia
  • HIV
  • organ transplantation
  • blood cancers
  • issues that disrupt the mechanics of the lungs, such as paralysis, intubation, surgery, or immobilization

The best way to clear a buildup depends on the underlying cause and contributing factors.

Common home care strategies include:

  • using an over-the-counter (OTC) saline nasal spray
  • taking OTC nondrowsy decongestants or antihistamines
  • rubbing a product that contains eucalyptus oil on the chest and throat or inhaling it
  • avoiding all allergens, including those in foods
  • gently pounding or tapping on the back and chest repeatedly to loosen the mucus
  • adding humidity to the air — using a humidifier or taking a warm shower or bath
  • applying a warm, moist washcloth over the face
  • covering the nose with a scarf in cold weather
  • not smoking and avoiding secondhand smoke

Many natural products can reduce mucus buildups or treat the respiratory conditions that cause them. Natural remedies with some scientific backing include:

  • licorice root
  • most berries
  • echinacea
  • ginseng
  • eucalyptus oil

If a buildup of mucus is severe or persistent, it can lead to:

  • dehydration
  • postnasal drip
  • a sore throat
  • sinus or nasal pain or pressure
  • jaw pain
  • dry mouth
  • a cough
  • lung, nasal, sinus, or throat infections
  • digestive problems
  • weight loss
  • trouble breathing
  • reduced oxygen levels and increased circulating carbon dioxide levels
  • atelectasis, in which the lungs cannot fully expand or collapse
  • respiratory failure
  • heart failure

When excessive mucus production or buildups happen with no clear cause, contact a healthcare provider.

Also seek professional care if mucus:

  • is very thick
  • has a color — healthy mucus is clear
  • interferes with breathing
  • does not respond to home treatment
  • lasts longer than a week or two

Also, talk to a doctor if troublesome mucus occurs with:

  • a fever or chills
  • unexplained exhaustion
  • trouble sleeping
  • wheezing or noisy breathing
  • breathing changes, such as rapid, shallow breathing or shortness of breath
  • a lack of appetite or weight loss
  • chest pain or pain when breathing
  • pus or blood
  • a cough
  • nausea and vomiting
  • acid reflux
  • a severe sore throat
  • rash on the chest, throat, or neck
  • bluish or pale coloring of the skin, especially around the fingers, toes, and lips
  • swelling of the throat, neck, head, feet, or ankles
  • confusion or other changes in mental functioning or state

Mucus is key to the functioning of vital organs and the immune system, so the body is continually producing it.

Several health issues can lead to a buildup of mucus or cause the body to produce excess. This can lead to complications.

Usually, OTC products and home care techniques can clear excess mucus. Contact a doctor if a mucus buildup has no clear cause, does not resolve with home care, or occurs alongside any other concerning symptoms.

Why Am I Coughing Up Mucus?

If you’re coughing up mucus, you’re probably having what’s known as a productive cough, or a cough that clears your airways.1 Phlegmy coughs can be attributed to several different underlying causes, so keep reading to explore them all.

What Is Mucus?

Mucus, also known as snot or phlegm, is a protective substance that your body excretes from your mouth, nose, sinuses, throat and lungs. Mucus is largely made up of mucin—a viscous substance that forms a barrier or lubricant to protect the surface of your body.2 If you feel congested and start producing wet coughs, you probably have excess mucus in your throat or lungs. 1

Why Am I Creating Excess Mucus?

You usually only notice your mucus when there’s too much of it or its consistency changes.3 There are a few potential causes of increased mucus production, including an infection. A viral infection inflames the mucus membranes lining your sinuses and causes them to produce more mucus. The mucus continues to thicken when certain cells and bacteria arrive to fight off the infection. Excess mucus production can cause a runny or stuffy nose, a cough or post-nasal drip, which is the feeling of mucus from the back of your nose running down your throat.3

What Does a Wet Cough Indicate?

There are a few different types of coughs, but the type of cough that produces mucus or phlegm is called a productive or wet cough. Usually, a wet cough is a symptom of some other type of ailment. Some of the most common causes of a wet cough include:3,4,5,6

  • Allergies: Things like pollen, animal dander and dust can all cause allergy sufferers to create more mucus. When your allergies flare up, your airways start to produce histamines, which can cause sneezing, coughing and watery eyes.
  • Common colds: Your body produces more mucus when you have a cold, and some of that mucus drains down your throat, causing post-nasal drip and a wet cough.
  • Sinus infections: While a cold is a viral infection of the lungs and throat, a sinus infection is caused by bacteria. Sinus infections inflame the tissues that line your sinuses and cause them to produce extra mucus. Like a cold, if you experience post-nasal drip from a sinus infection, you might start coughing up mucus.
  • Bronchitis: Air enters your lungs through your bronchial tubes. These tubes secrete mucus to trap irritants and other particles before they can get to your lungs. If they become inflamed and infected, your body produces more mucus to fight off the invaders. This can eventually lead to bronchitis and a severe cough.

What Does the Color of My Mucus Mean?

Mucus and nasal discharge come in a variety of different colors, including yellow, green, clear and more. A sinus infection or a cold can change the color of your mucus, but other factors, such as seasonal allergies, can do the same. The different shades of mucus are as follows:7,8

  • Clear mucus: Mucus is usually clear due to its makeup of mucin, water, dissolved salt, proteins and antibodies. Your body produces clear mucus 24/7.
  • White mucus: If you’re congested, your mucus might become thicker and cloudier. The flow of your mucus gets interrupted when your nasal passages are swollen, causing it to lose moisture and subsequently become more viscous.
  • Yellow or green mucus: When the white blood cells in your mucus see a threat, they fight off the invaders using enzymes. These enzymes contain iron, which gives the nasal discharge its green or yellow color. Mucus that sits in your sinuses or chest can get darker the longer it’s there. This could be a sign that you have an infection, but other factors, such as how you’re feeling and whether you have a fever, should also be considered.

Now that you know the reason why you’re coughing up mucus, you can start to treat your symptoms accordingly.

what is it, types, causes, diagnosis, how to treat, preventive measures

Cough interferes with free breathing, sleep and affects performance. This symptom impairs the quality of life to such an extent that it occupies a leading place among the reasons for seeking medical help at the polyclinic 1 . In the article we will tell you why a wet cough occurs, and when you can get rid of it yourself, and when it is better to consult a doctor.

What is a wet cough

Coughing is a protective reflex that clears the airways. Often it occurs in response to irritation of cough receptors located in the nasal cavity, pharynx, trachea, bronchi. Less often – due to irritation of the vagus nerve, the branches of which go to the outer ear, epiglottis, pleura, diaphragm, esophagus and pericardium – the outer shell of the heart. The irritant can be temperature changes, foreign objects, chemicals, inflammation.

If sputum is secreted when coughing, it is considered wet. Sputum is produced in response to inflammation when the goblet cells of the respiratory tract epithelium begin to produce an increased amount of mucus 2 . This disrupts the work of the ciliary epithelium, which should bring the mucus out. Because of this, it stagnates, becomes more viscous, microflora multiplies in it.

Signs of a wet cough

The main symptom of a wet cough is sputum production. But it happens that the bronchial secret is too viscous, and the work of the cilia of the epithelium is disturbed, for example, due to inflammation. Then the sputum does not go away, but lingers in the body. In this case, it is possible to distinguish a wet cough from a dry one by listening to the lungs (auscultation). Sometimes wet rales during breathing are heard even without a phonendoscope.

What causes a wet cough

Infections. In 67% of cases in adults, cough occurs due to a respiratory tract infection. Probably, these figures are slightly underestimated, since not all sick people go to the doctor. 3

The drug Nobasit ® Forte (enisamia iodide 500 mg) for the treatment of acute respiratory viral infections was included in the guidelines of the Ministry of Health of the Russian Federation back in 2020. 4 During a clinical study conducted in 2018-2019gg. on the basis of the Research Institute of Influenza. A.A. Smorodintsev, it was found that while taking enisamium iodide, the number of complications requiring antibiotics was 4 times lower compared to the symptomatic therapy group. 5 Timely initiation of treatment of enisamia with iodide, an etiotropic drug against acute respiratory viral infections Nobazit ® Forte, helps to reduce the risks of a complicated course and the spread of infection to the lower respiratory tract. 5

Wet cough cause 6 :

● viruses — rhinoviruses, coronaviruses, influenza, parainfluenza, respiratory syncytial virus and others;

● bacteria – Koch’s bacillus, staphylococci, pneumococci, Haemophilus influenzae;

● intracellular parasites – chlamydia, mycoplasmas;

● fungi – of the genus Candida;

● protozoa – pneumocystis.

Due to inflammation in the bronchi, swelling or spasm occurs, and the lumen narrows. It becomes more difficult to remove sputum, so it accumulates and irritates the bronchi, which causes a coughing fit.

Infectious diseases that cause a wet cough:

● bronchitis;

● pharyngitis;

● laryngitis;

● pneumonia;

● sinusitis – inflammation of the paranasal sinuses, including sinusitis;

● tonsillitis – inflammation of the tonsils;

● tracheitis – inflammation of the trachea 7 ;

● tuberculosis;

● whooping cough;

● Tumors of the mediastinum and lungs.

Cough can also occur due to irritation of the respiratory system, as well as against the background of fluid accumulation in the lungs.

Noninfectious causes . Diseases in which cough is not associated with infections:

● adenoiditis – growth of the tonsils in the nasopharynx;

● allergic rhinitis;

● bronchial asthma;

● cystic fibrosis;

● malformations of the bronchi;

● heart failure;

● gastroesophageal reflux;

● syndrome of primary ciliary dyskinesia – a defect in the cilia of the epithelium of the respiratory tract, which interferes with the normal removal of sputum;

● bronchiectasis – expansion of the bronchi with the destruction of part of their walls and the accumulation of pus in the resulting cavity;

● laryngeal fissures and tracheoesophageal fistulas 8 ;

● interstitial lung disease – thickening of the walls of the lungs.

Species of sputum

A wet cough most often indicates an infection. It is possible to determine its viral or bacterial origin, as well as to establish the focus of the lesion by the appearance of sputum 9 :

● white or clear sputum is characteristic of viral infections;

● yellow or green – for bacterial lesions;

● red or pink with an admixture of blood – for tuberculosis and ruptured blood vessels in the lungs;

● dark yellow or brown – for pneumonia, for smokers;

● black sputum – for long-term inhalation of coal dust;

● thick sputum – for bronchitis;

● sputum with lumps – for fungal infections (mycosis) and cystic fibrosis.

Is cough with sputum contagious

It depends on the cause of the cough. The sputum of people with respiratory tract infections contains a large number of germs. With a cough, sputum falls on objects and surfaces, and the smallest charged particles settle in the air. Healthy people become infected by inhaling the air in the same room with the sick or by touching contaminated objects first, and then to the face.

Cough with sputum is contagious at:

● Influenza and other SARS (including COVID-19), while other symptoms persist (runny nose, fever, feeling worse) and a few more days after they disappear. With a residual cough that may bother for several more weeks, the patient is not contagious.

● Tuberculosis of the lungs in an open form. In the closed form, there are no bacteria in the sputum. Only a doctor can determine which form the patient has with the help of special tests and analyzes.

● Whooping cough. The patient remains contagious for about a month from the moment the first signs of the disease appear. It is worth mentioning that with whooping cough, the cough is mostly dry and becomes wet (unproductive) closer to recovery.

● Pneumonic plague, anthrax – extremely dangerous, but rare bacterial infections these days.

In chronic bronchitis, COPD, pulmonary emphysema, tumors and other non-infectious diseases, a patient with a wet cough does not pose a danger to others.

Disease diagnosis

To make a diagnosis, the doctor will listen to complaints and examine the patient. Usually, rhinoscopy is performed – they examine the nasal passages and “listen” to the chest. This allows you to immediately identify or weed out some diseases – for example, allergic rhinitis, sinusitis, bronchial asthma or bronchitis.

To clarify the diagnosis, sputum can be examined under a microscope and cultured on nutrient media to find out what microflora lives in the patient’s respiratory system.

If the cough is chronic and treatment does not help, the patient will be prescribed an X-ray or CT scan of the lungs, which will help determine pneumonia, tuberculosis, tumors and other diseases.

How to get rid of a cough with phlegm

Viruses are the main cause of wet cough. Studies show that, without treatment, one in ten of those surveyed have a cough that lasts up to a month, a quarter lasts longer than two weeks, and half last up to two weeks. This suggests that it is impossible to wait until the unpleasant symptom passes – cough must be treated 10 .

Non-drug treatment. There are several universal recommendations to make you feel better. For example, regularly ventilate the room – this will facilitate the access of oxygen to the lungs. Try to walk outside more often. Movement helps clear the airways and expel mucus. Additionally, you can do chest massage and breathing exercises to improve sputum excretion.

Medical treatment. It is necessary to start taking medication from the moment when the cough is still dry and sputum is difficult to separate. In this case, the effectiveness of therapy is higher.

What drugs are suitable for the treatment of wet cough:

● Mucolytics. These are mucus thinners. They are most effective on the 1st-4th day of illness, because they reduce the viscosity of sputum and fewer microbes linger in it 11 .

● Expectorants. The drugs increase the activity of the epithelium of the respiratory tract and the contractility of the bronchi, facilitating the removal of sputum from the lungs 12 .

● Bronchodilators. They relieve spasm of the bronchi, expanding their lumen, allow you to breathe normally.

● Antihistamines. Assign with an allergic nature of cough.

It is important to deal not only with the cough itself, but also with its cause. Since viruses often cause the disease, antiviral agents are used for treatment. They are divided into three groups:

● direct-acting antiviral drugs – suppress the reproduction of the virus at different stages of the cycle;

● interferons, for example, α-interferon – ready-made synthetic antiviral proteins that help the immune system fight the virus, but these drugs can cause side effects and their effectiveness decreases with prolonged use;

● interferon inducers – stimulators of the production of their own interferon, which enhance natural immunity, do not cause addiction and side effects.

If a patient has a bacterial infection, antibiotics are prescribed. The drug and dosage depend on the type of bacteria, the age of the patient and the presence of chronic diseases.

What to do if sputum does not come out

When sputum is separated with difficulty, the patient is disturbed by a painful cough, which significantly reduces the quality of life. Sputum stagnation in the respiratory tract is dangerous. In acute respiratory viral infections, it increases the risk of developing pneumonia, bacterial complications; in chronic diseases of the bronchi and lungs, it provokes purulent and putrefactive processes. Therefore, mucus must be removed.

With the ineffectiveness of drug therapy, sputum discharge can be stimulated by drinking plenty of water, special breathing exercises, and the use of herbal preparations. Of course, any therapy should be discussed with the attending physician.

If it is impossible to independently cough up sputum, a special device is used – an aspirator.

When to see a doctor

Adults can treat uncomplicated cough on their own. But in some cases, it is necessary to consult with a specialist. It is worth contacting a doctor 13 :

● if the cough persists for a long time;

● if there is pain in the chest;

● when there is an admixture of blood in the sputum, even a slight one;

● with difficulty breathing and shortness of breath;

● with concomitant pathologies of the cardiovascular system or symptoms of these pathologies;

● with installed gastrostomy;

● with hernias of the abdominal cavity, esophagus;

● with gastroesophageal disease;

● with cysts in the liver due to the risk of their rupture;

● in case of cerebrovascular accident or stroke in the past;

● with performed arterial bypass surgery;

● With peritoneal dialysis.

Forecast

The prognosis depends on the disease that caused the cough, the timeliness of treatment. With SARS and whooping cough, cough is most often completely cured. If the patient ignores the doctor’s prescription, is weakened or smokes, an acute cough can turn into a chronic one. In this case, irreversible changes occur in the bronchi (chronic bronchitis, COPD), and coughing is very common. Frequent SARS and bronchitis can also be complicated by another chronic disease – bronchial asthma.

Chronic diseases cannot be completely cured, but modern therapy allows maintaining a good quality of life for such patients for many years. To do this, anti-inflammatory drugs often have to be taken in long courses.

If a wet cough is caused by bronchopulmonary cancer, the prognosis is cautious, closer to unfavorable. Cough most often indicates an advanced tumor. But even in such cases, surgery, chemotherapy or radiation therapy often help to significantly prolong life.

Preventive measures

Cough prevention includes:

● Fight against colds: annual flu vaccination, prophylactic use of antiviral during an outbreak, limiting contact with other people, frequent hand washing, wearing a mask.

● Prevent hypothermia.

● Stop smoking tobacco, electronic cigarettes.

● Timely treatment of allergic and cardiovascular diseases.

● Wear a respirator when working in contaminated air.

Briefly about the main

➢ Wet is considered a cough that produces sputum. It occurs when, due to irritants or inflammation, the production of mucus increases, and the lumen of the bronchi narrows. To remove mucus from the respiratory tract, a person needs to cough up.

Wet cough is caused by viral, bacterial and fungal infections, as well as allergic diseases and other pathologies of internal organs. But most often the symptom is associated with viral diseases.

➢ Uncomplicated cough can be treated on its own. But you must definitely consult a doctor if the patient has pathologies of the cardiovascular system or with symptoms characteristic of them, he is weakened after the operation.

➢ For the treatment of cough, mucolytics, bronchodilators, antihistamines and antitussives are prescribed. But one symptomatic therapy is not enough. To eliminate the cause of the disease, depending on the type of pathogen and the nature of its course, antiviral and antibiotics are prescribed.

Sputum as a diagnostic sign of respiratory diseases

What is sputum?

Under normal conditions, a person has a clear mucus on the mucous membrane of the bronchi and trachea, the so-called bronchotracheal secretion. It is produced by the cells of the bronchial mucosa and performs the most important protective and cleansing function, and also moisturizes the bronchi.

With the help of the ciliated epithelium located on the inner walls of the bronchi, the mucus moves towards the pharynx. Together with the mucus, microbes, dust, and dead cells that have entered the bronchi are removed. In addition, mucus is endowed with bactericidal properties due to the presence of immune cells. When pathogens enter, these cells immediately react and destroy them.

When we are healthy, we simply swallow a certain amount of bronchotracheal secretion without noticing it.

When an inflammatory process develops in the respiratory organs, the amount of mucus increases sharply, pus, blood, leukocytes penetrate into it, mucous contents flow from the nose, which becomes viscous and acquires a shade. It can be green, yellow-green, rusty, brown, pink. This is the wetness.

Sputum is coughed up, in the absence of a cough it can accumulate in the throat.

The accumulation of sputum is a warning that something is wrong with the respiratory system. The color of sputum can also be used to judge the nature of the disease.

Sputum accumulates, but no cough

This may be in inflammatory diseases of the ear, nose and throat:

  • rhinitis, including vasomotor
  • sinusitis,
  • tonsillitis,
  • pharyngitis.

Sputum can also form in a healthy person:

  • inhalation of a large amount of foreign particles, for example, in production workshops,
  • when eating spicy or very hot food, due to throat irritation,
  • when smoking.

Sputum is removed with a cough

Such sputum indicates pathological processes occurring in the lungs or bronchi. The cause may be inflammatory processes (bronchiectasis, pneumonia, bronchitis), tumor, allergies, congestion.

Of course, one cannot make a diagnosis based on the presence of sputum or its color, but one can draw conclusions about the nature of the disease. A thorough additional examination of the patient is necessary – sputum, blood, X-ray, MRI and CT studies.

Greenish sputum

Greenish or yellow-green sputum when coughing indicates inflammatory processes in the lungs or bronchi, including acute bronchitis and pneumonia of bacterial origin. In this case, the sputum is viscous and sticky, which is due to the presence of pus. Often, such sputum can form after a runny nose, flu. This means that a bacterial infection has joined the viral infection. As a rule, with these diseases, there is a high temperature, weakness, shortness of breath.

Greenish or yellow-green sputum is also formed during exacerbation of bronchiectasis. With this chronic pathology, the bronchi are modified and expanded, purulent processes are inherent in it.

Viscous green sputum, accompanied by nasal congestion, loss of the sense of smell, but without cough, is inherent in chronic sinusitis.

With pulmonary tuberculosis, green sputum is observed in remission.

Yellowish sputum

Such mucus is formed exclusively during complicated bronchitis and pneumonia. With a prolonged (more than a month) persistent cough and yellowish sputum, it can be suspected that the inflammatory disease has become chronic.

The bright yellow color of sputum is characteristic of the so-called eosinophilic pneumonia, which is allergic in nature. In this case, the yellow color of sputum is due to a large number of eosinophils, which are a type of white blood cell.

Yellow sputum also occurs in smokers (“smoker’s bronchitis”), this shade is due to tar and nicotine.

Sputum with a reddish tinge

Blood gives reddish tint to sputum. At times, in the sputum, you can see red strands, which can be observed with incompletely cured, prolonged pneumonia, lung abscess, incipient tuberculosis, and pleurisy. Reddish discharge is a formidable warning, in which an appeal to a specialist becomes a vital necessity.

Brownish sputum

This pattern is observed when coagulated blood penetrates the mucus. In many cases, this is a threatening sign. What is he warning about? Possible options: active tuberculosis, lung cancer, pulmonary embolism, lung gangrene. This symptom can manifest itself in chronic pneumonia and bronchitis.

There may be less serious causes of brownish sputum, for example, blood can enter the sputum from small bleeding wounds in the mouth. At times, brown sputum occurs in smokers when bronchitis progresses to chronic obstructive pulmonary disease.

Scarlet and pink sputum

The scarlet color of sputum is due to the presence of a significant amount of blood. This is a symptom of lung cancer or pulmonary embolism.

Pink and viscous sputum is observed in the severe stage of tuberculosis. Foamy sputum may indicate pulmonary edema.

In pneumonia caused by pneumococci, sputum is initially pink, which later acquires a “rusty” hue.
