Understanding Viral Gastroenteritis: The Stomach Flu Explained

Viral gastroenteritis, commonly known as the stomach flu, is a highly contagious intestinal inflammation caused by various viruses. This ailment affects millions worldwide and can spread rapidly in close-quarter environments. Despite its colloquial name, it’s not related to influenza, which primarily affects the respiratory system.

Key Characteristics of Viral Gastroenteritis

• Caused by viruses, not bacteria
• Highly contagious
• Can affect people of all ages
• Symptoms typically last 1-14 days
• Often referred to as “stomach flu”

Gastroenteritis can be particularly challenging in settings where people are in close proximity, such as schools, childcare facilities, nursing homes, and cruise ships. The ease of transmission in these environments makes understanding the illness crucial for prevention and management.

Recognizing the Symptoms: What Does Viral Gastroenteritis Feel Like?

The onset of viral gastroenteritis symptoms is often sudden, typically developing within 12 to 48 hours after exposure to the virus. However, in some cases, such as with adenoviruses, symptoms may not appear for 3 to 10 days post-infection.

Common Symptoms of Viral Gastroenteritis

• Watery diarrhea (more than 3 times daily)
• Nausea and vomiting
• Fever or chills
• Abdominal cramps and pain
• Headache, muscle aches, or joint pain
• Loss of appetite
• Sweating or clammy skin

Is bloody diarrhea a symptom of viral gastroenteritis? Typically, diarrhea caused by viral gastroenteritis is not bloody. The presence of blood in stool could indicate a more severe infection and requires immediate medical attention.

When to Seek Medical Help

While most cases of viral gastroenteritis resolve on their own, certain symptoms warrant medical intervention:

• Diarrhea lasting more than 2 days without improvement
• Blood in stool
• Signs of dehydration (dry lips, dizziness)
• Infants developing diarrhea

For children, additional warning signs include sunken eyes and lack of tears when crying. These symptoms may indicate severe dehydration and require immediate medical attention.

The Culprits Behind the Illness: Common Viruses Causing Gastroenteritis

Several viruses can cause viral gastroenteritis, each with its own characteristics and patterns of infection. Understanding these viruses can help in prevention and management of the illness.

Norovirus: The Leading Cause of Gastroenteritis

Norovirus is the most common cause of viral gastroenteritis worldwide. It’s notorious for its high contagiousness and ability to affect people of all ages.

• Highly contagious
• Affects all age groups
• Most outbreaks in the U.S. occur between November and April
• Symptoms include nausea, diarrhea, fever, and body aches
• Most people recover within 1 to 3 days

How long do norovirus symptoms typically last? According to the Centers for Disease Control and Prevention (CDC), most people start feeling better within 1 to 3 days after symptoms begin.

Rotavirus: A Major Concern for Young Children

Rotavirus primarily affects infants and young children, though it can spread to adults who come into contact with infected individuals.

• Commonly affects infants and young children
• Transmitted via oral route
• Symptoms typically appear within 2 days of infection
• Can cause severe diarrhea in young children

Why is rotavirus particularly concerning for young children? Rotavirus can cause severe diarrhea in infants and young children, leading to rapid dehydration. This makes it a significant health concern in this age group.

Adenovirus: A Less Common but Potent Cause

Adenoviruses can cause a range of illnesses, including gastroenteritis. They’re less common than norovirus or rotavirus but can still lead to significant outbreaks.

• Can cause respiratory and intestinal infections
• Symptoms may be delayed 3 to 10 days after exposure
• Often affects young children

Astrovirus: Another Contributor to Gastroenteritis

Astroviruses are another group of viruses that can cause gastroenteritis, particularly in young children and the elderly.

• Often causes mild symptoms
• More common in winter months
• Can affect people of all ages, but more frequent in children

Transmission and Risk Factors: How Does Viral Gastroenteritis Spread?

Understanding how viral gastroenteritis spreads is crucial for prevention. The illness is highly contagious and can be transmitted through various means.

Common Transmission Routes

• Consuming contaminated food or water
• Close contact with infected individuals
• Sharing utensils or personal items with someone who has the virus
• Touching contaminated surfaces
• Poor hand hygiene, especially among food handlers

Why is proper hand hygiene crucial in preventing viral gastroenteritis? Thorough hand washing is one of the most effective ways to prevent the spread of the viruses that cause gastroenteritis. It’s particularly important after using the bathroom, changing diapers, and before handling food.

High-Risk Groups for Viral Gastroenteritis

While anyone can contract viral gastroenteritis, certain groups are at higher risk:

• Children under 5 years old
• Older adults, especially those in nursing homes or assisted living facilities
• Individuals with weakened immune systems
• People in group settings (schools, dormitories, day care centers)

Additional Risk Factors

Several other factors can increase the likelihood of contracting viral gastroenteritis:

• Malnutrition, particularly low levels of vitamin A or zinc
• Recent travel to developing countries
• Use of antibiotics or antacids
• Engaging in anal intercourse

How does malnutrition increase the risk of viral gastroenteritis? Malnutrition, especially deficiencies in vitamin A and zinc, can weaken the immune system, making individuals more susceptible to viral infections, including those causing gastroenteritis.

Prevention Strategies: Keeping Viral Gastroenteritis at Bay

While viral gastroenteritis is highly contagious, there are several effective strategies to reduce the risk of infection and prevent its spread.

Personal Hygiene Practices

• Frequent and thorough hand washing with soap and water
• Using alcohol-based hand sanitizers when soap and water are unavailable
• Avoiding touching face, especially mouth and nose, with unwashed hands
• Covering mouth and nose when coughing or sneezing

Food and Water Safety

• Washing fruits and vegetables thoroughly before consumption
• Cooking food, especially seafood, thoroughly
• Avoiding raw or undercooked meats
• Using safe water sources for drinking and food preparation
• Properly storing and refrigerating perishable foods

Why is proper food handling crucial in preventing viral gastroenteritis? Many outbreaks of viral gastroenteritis are linked to contaminated food. Proper food handling, including thorough cooking and safe storage, can significantly reduce the risk of viral contamination and transmission.

Environmental Measures

• Regularly cleaning and disinfecting frequently touched surfaces
• Promptly washing clothing and bedding contaminated with vomit or fecal matter
• Isolating individuals with symptoms to prevent spread

Vaccination

While there isn’t a vaccine for all types of viral gastroenteritis, rotavirus vaccines are available and recommended for infants. These vaccines have significantly reduced the incidence of severe rotavirus infections in many countries.

How effective are rotavirus vaccines in preventing gastroenteritis in infants? Rotavirus vaccines have been highly effective in reducing severe rotavirus infections in infants and young children. In many countries where the vaccine is routinely administered, hospitalizations due to rotavirus have decreased by 80% or more.

Treatment Approaches: Managing Viral Gastroenteritis Symptoms

There is no specific cure for viral gastroenteritis, and antibiotics are ineffective against viruses. Treatment primarily focuses on managing symptoms and preventing complications, particularly dehydration.

Hydration: The Cornerstone of Treatment

• Drinking plenty of clear fluids to replace lost fluids and electrolytes
• Using oral rehydration solutions, especially for children and the elderly
• Avoiding caffeine and alcohol, which can worsen dehydration

Why are oral rehydration solutions particularly important in treating viral gastroenteritis? Oral rehydration solutions are specially formulated to replace both fluids and electrolytes lost through diarrhea and vomiting. They’re more effective than water alone in preventing and treating dehydration, especially in children and the elderly.

Dietary Considerations

• Gradually reintroducing food as tolerated
• Starting with bland, easily digestible foods (BRAT diet: Bananas, Rice, Applesauce, Toast)
• Avoiding dairy products, fatty foods, and high-fiber foods initially

Medication Management

While medications don’t cure viral gastroenteritis, some may help manage symptoms:

• Anti-emetics to control nausea and vomiting
• Pain relievers for fever and body aches
• Probiotics to help restore normal gut flora

Is it safe to use over-the-counter anti-diarrheal medications for viral gastroenteritis? In most cases, it’s best to avoid anti-diarrheal medications, especially for children. These medications can prolong the infection by preventing the body from eliminating the virus. Always consult a healthcare provider before using such medications.

Rest and Recovery

Adequate rest is crucial for recovery from viral gastroenteritis. It allows the body to focus energy on fighting the infection and healing.

Long-Term Impact and Complications: Beyond the Acute Phase

While most cases of viral gastroenteritis resolve without long-term consequences, in some instances, complications can occur, particularly in vulnerable populations.

Potential Complications

• Severe dehydration
• Electrolyte imbalances
• Malnutrition, especially in prolonged cases
• Rarely, post-infectious irritable bowel syndrome

Can viral gastroenteritis lead to long-term digestive issues? In some cases, individuals may experience prolonged digestive symptoms after a bout of viral gastroenteritis. This condition, known as post-infectious irritable bowel syndrome, can persist for weeks or months after the initial infection has cleared.

Special Considerations for Vulnerable Groups

Certain populations may be at higher risk for complications and may require closer monitoring:

• Infants and young children
• Elderly individuals
• People with compromised immune systems
• Those with chronic health conditions

Recovery and Follow-up Care

Most people recover fully from viral gastroenteritis without any specific treatment. However, it’s important to:

• Monitor for signs of dehydration or worsening symptoms
• Gradually return to normal diet and activities
• Seek medical attention if symptoms persist or worsen

How long should one wait before returning to work or school after viral gastroenteritis? Generally, individuals should stay home for at least 24-48 hours after symptoms have resolved to prevent spreading the virus. However, some viruses, like norovirus, can continue to be shed in stool for days or weeks after recovery, so maintaining good hygiene practices is crucial.

Global Impact and Public Health Measures: Viral Gastroenteritis on a Larger Scale

Viral gastroenteritis is a significant public health concern worldwide, affecting millions of people annually and causing substantial economic burden.

Economic and Social Impact

• Lost productivity due to illness
• Healthcare costs for treatment and hospitalization
• Disruption of daily activities and social events

Public Health Strategies

Public health organizations implement various strategies to combat viral gastroenteritis:

• Surveillance systems to monitor outbreaks
• Public education campaigns on prevention and hygiene
• Implementation of food safety regulations
• Vaccination programs, particularly for rotavirus

How have public health measures impacted the prevalence of viral gastroenteritis? Public health interventions, such as improved sanitation, food safety regulations, and vaccination programs, have significantly reduced the incidence and severity of viral gastroenteritis in many parts of the world. However, it remains a persistent challenge, particularly in resource-limited settings.

Research and Development

Ongoing research aims to improve understanding and management of viral gastroenteritis:

• Development of new vaccines
• Improved diagnostic techniques
• Studies on virus transmission and environmental persistence
• Investigation of potential antiviral treatments

Viral gastroenteritis, while often a self-limiting illness, remains a significant public health concern due to its high transmissibility and potential for severe symptoms, especially in vulnerable populations. Understanding its causes, symptoms, and prevention strategies is crucial for individuals and communities alike. By implementing proper hygiene practices, maintaining food safety, and staying informed about public health recommendations, we can reduce the impact of this common but potentially serious illness.

Viral gastroenteritis is caused by a number of different viruses. It’s easy for these viruses to spread in group situations. Some of the ways the virus is transmitted include:

• eating contaminated food or drinking contaminated water
• being in close contact with someone who has the virus
• sharing utensils or other items with someone who has the virus
• touching contaminated surfaces
• not washing hands properly, especially food handlers

Viral gastroenteritis affects people of all ages all over the world. But some factors can increase the risk of contracting viral gastroenteritis. People who are at a higher risk include:

• children under the age of 5
• older adults, especially those who live in nursing homes or assisted living facilities
• people with a compromised or weakened immune system
• those who are often in group settings, such as schools, dormitories, day care, religious gatherings, and other indoor group settings

Other factors that may increase the risk of becoming ill with viral gastroenteritis include:

• being malnourished, especially low levels of vitamin A or zinc
• recent travel to developing countries
• antibiotic or antacid use
• anal intercourse

Several different types of viruses can cause viral gastroenteritis. The most common include:

• norovirus
• rotavirus
• adenovirus
• astrovirus

Let’s look at each of these viruses in more detail.

Norovirus

Norovirus is highly contagious and can affect anyone at any age. It spreads through contaminated food, water, and surfaces, or by people who have the virus. Norovirus is common in crowded spaces.

Norovirus is the leading cause of gastroenteritis in the United States and worldwide. Most outbreaks in the United States occur between November and April.

Symptoms include:

• nausea
• diarrhea
• fever
• body aches

According to the Centers for Disease Control and Prevention (CDC), most people who become ill with norovirus start to feel better within 1 to 3 days of symptom onset.

Rotavirus

Rotavirus commonly affects infants and young children. Those who contract it can then pass the virus to other children and adults. It’s usually contracted and transmitted via the mouth.

Symptoms typically appear within 2 days of infection and include:

• vomiting
• loss of appetite
• watery diarrhea that lasts anywhere from 3 to 8 days

A rotavirus vaccine was approved for infants in 2006. Early vaccination is recommended to prevent severe rotavirus illnesses in infants and small children.

Adenovirus

The adenovirus affects people of all ages. It can cause several types of illness, including gastroenteritis. The adenovirus can also cause common cold-like symptoms, bronchitis, pneumonia, and pink eye (conjunctivitis).

Children in daycare, especially those under 2 years of age, are more likely to get adenovirus.

Adenovirus is passed through the air via sneezing and coughing, by touching contaminated objects, or by touching the hands of someone with the virus.

Symptoms associated with adenovirus include:

• sore throat
• pink eye
• fever
• coughing
• runny nose

Most children will feel better within a few days of experiencing adenovirus symptoms. However, symptoms such as pink eye may last longer than a few days.

Astrovirus

Astrovirus is another virus that commonly causes gastroenteritis in children. Symptoms associated with astrovirus include:

• diarrhea
• headache
• mild dehydration
• stomach pain

The virus most often affects people in late winter and early spring. It’s transmitted through contact with a person who has the virus or via an infected surface or food.

Symptoms usually appear within 2 to 3 days after initial exposure, and the virus will usually go away within 1 to 4 days.

The main complication of viral gastroenteritis is dehydration, which can be quite severe in babies and young children. Viral gastroenteritis accounts for over 200,000 childhood deaths worldwide per year.

Other complications of viral gastroenteritis include:

• nutritional imbalances
• body weakness or fatigue
• muscle weakness

Dehydration can be life threatening. Call your doctor if you or your child have these symptoms:

• diarrhea lasting more than a few days
• blood in the stool
• confusion or lethargy
• dizziness or feeling like you’re going to faint
• nausea
• dry mouth
• an inability to produce tears
• no urine for more than 8 hours or urine that is dark yellow or brown
• sunken eyes
• sunken fontanel on an infant’s head

Dehydration that accompanies viral gastroenteritis can lead to several complications of its own. These include:

• brain swelling
• coma
• hypovolemic shock, a condition that occurs when your body doesn’t have enough fluid or blood
• kidney failure
• seizures

To prevent complications, get immediate medical attention if you or your child have symptoms of dehydration.

Most of the time, your medical history and physical exam are the basis for diagnosis, especially if there’s evidence that the virus is spreading through your community.

Your doctor may also order a stool sample to test for the type of virus, or to find out if your illness is caused by a parasitic or bacterial infection.

The main focus of treatment is to prevent dehydration by drinking plenty of fluids. In severe cases, hospitalization and intravenous fluids may be necessary.

Over-the-counter oral rehydration solutions (OHS), such as Pedialyte, can be helpful in mild cases. These solutions are easy on your child’s stomach, and contain a balanced mixture of water and salts to replenish essential fluids and electrolytes.

These solutions are available at local pharmacies and don’t require a prescription. However, you should follow the instructions carefully.

Antibiotics have no effect on viruses. Check with your physician before taking any over-the-counter medications.

Shop online for oral rehydration solutions such as Pedialyte and oral electrolyte products.

Treating diarrhea and vomiting

Diarrhea can be treated in adults with over-the-counter medications such as loperamide (Imodium) or bismuth subsalicylate (Pepto-Bismol).

Your doctor may also prescribe probiotics to replace the healthy bacteria that’s lost during diarrhea or they may prescribe medications to treat severe vomiting.

What to eat and what to avoid

As you start to feel better and reintroduce foods into your diet, it’s best to opt for bland foods, such as:

• rice
• potatoes
• toast
• bananas
• applesauce

These foods are easier to digest and less likely to cause further stomach upset. Until you’re feeling better, you may want to avoid some types of foods, such as:

• fatty or fried foods
• caffeine
• alcohol
• sugary foods
• dairy products

Self-care steps

If you have viral gastroenteritis, consider these self-care measures to help ease your symptoms and prevent dehydration:

• Drink extra fluids with and between meals. If you have difficulty, try drinking very small amounts of water or sucking on ice chips.
• Avoid fruit juices. These don’t replace the minerals that you’ve lost and can actually increase diarrhea.
• Electrolytes. Children and adults can consume sports drinks to replenish electrolytes. Younger children and infants should use products formulated for children, such as OHS.
• Limit portion sizes. Try to eat food in smaller amounts to help your stomach recover.
• Get lots of rest. Prioritize getting at least 7 to 8 hours of sleep each night. Don’t exert yourself until you feel that you have your usual level of energy and strength.
• Medications. Check with your doctor before taking medications or giving them to children. Never give aspirin to children or teenagers with a viral illness. This can cause Reye’s syndrome, a potentially life threatening condition.

In addition to rehydrating and resting, there are some natural and home remedies that may help you relieve the symptoms of viral gastroenteritis.

Heating pad or heat pack

If you have abdominal pain, try applying a low-temperature heating pad or a warm heat pack to your stomach. Cover the heating pad with a cloth and don’t leave it on for more than 15 minutes at a time.

The heat can help relax the muscles in your digestive tract and keep them from spasming.

Shop online for heating pads and heat packs.

Brown rice water

Some parents serve rice water to their children. This is the water that remains after boiling brown rice. It’s high in electrolytes and can help with rehydration.

To make rice water:

1. Boil 1 cup of rice and 2 cups of water for about 10 minutes until the water becomes cloudy.
2. Strain the rice and keep the water.
3. Cool the rice water before serving.

Ginger

Products containing ginger, such as ginger ale or ginger tea, may help soothe an upset stomach.

A 2019 review of studies found that a divided daily dose of 1,500 milligrams of ginger taken in two parts throughout the day may help reduce nausea. More research needs to be done on ginger’s ability to treat other gastrointestinal symptoms.

Shop online for ginger ale and ginger tea.

Mint

Mint may also have anti-nausea properties similar to those of ginger. Sipping a soothing mint tea may help you feel better.

Studies have found that peppermint oil may help relax the muscles in your gut. It also has anti-microbial and anti-inflammatory properties.

Shop online for mint tea.

Yogurt or kefir

Although dairy products should be avoided when you have your most acute symptoms, eating unflavored yogurt with live active cultures or drinking kefir may help restore your body’s natural bacterial balance after illness.

Shop online for plain yogurt and kefir.

Viral gastroenteritis can spread easily. However, there are some steps you can take to lower your risk of contracting the virus or passing it to others.

Prevention tips

• Wash your hands often, especially after using the bathroom and before food preparation. If necessary, use hand sanitizer until you can access soap and water.
• Don’t share kitchen utensils, plates, or towels if someone in your household is sick.
• Don’t eat raw or undercooked foods.
• Wash fruits and vegetables thoroughly.
• Take special precautions to avoid contaminated water and food when traveling. Avoid ice cubes and use bottled water whenever possible.
• Ask your doctor if you should have your infant vaccinated against rotavirus. There are two vaccines, and they’re generally started around 2 months old.

Enteroviral infection

09/18/2017

Enterovirus infection is a multiple group of acute infectious diseases that can affect children and adults when infected with viruses of the Enterovirus genus. The insidiousness of the causative agents of enterovirus infection is that they can cause various forms of clinical manifestations, from mild malaise to serious damage to the central nervous system. With the development of an enterovirus infection, the symptoms are characterized by a feverish state and a wide variety of other signs caused by damage to the respiratory system, gastrointestinal tract, kidneys, central nervous system and other organs.

How the infection spreads:

The main route of transmission of enterovirus infection is fecal-oral .
Household contact , through household items, contaminated hands, if personal hygiene is not observed.
Airborne if the pathogen multiplies in the respiratory tract, when coughing, sneezing.
Waterway – infection can occur when vegetables and fruits are watered with contaminated sewage, as well as when swimming in open contaminated water bodies, according to some reports, even water in coolers is a source of enterovirus infection.
If a pregnant woman is infected with an enterovirus infection, a vertical route of the pathogen’s transmission to the child is also possible.

Enterovirus infection is characterized by summer-autumn seasonality, a person has a very high natural susceptibility, and after the illness, type-specific immunity is maintained for several years.
The incubation period of any enteroviral infections is no more than 2-7 days.

All diseases that can be caused by enteroviruses according to the severity of the inflammatory process can be conditionally divided into 2 groups:0017 Serious diseases
These include acute paralysis, hepatitis, serous meningitis in children and adults, pericarditis, myocarditis, neonatal septic-like diseases, any chronic infections in HIV-infected people (HIV infection: symptoms, stages).
Less severe diseases
Conjunctivitis, three-day fever without rash or with rash, herpangina, vesicular pharyngitis, pleurodynia, uveitis, gastroenteritis. Enterovirus D68 can occur with severe cough and bronchopulmonary obstruction.

Symptoms:

Signs of SARS . Children develop perspiration, sore throat, sometimes runny nose, cough, fever. The temperature is high at the first stages, then decreases and after 2-3 days it jumps sharply again. This phenomenon is called “enterovirus fever”. It lasts, as a rule, 3 days, the child will feel unwell. During this period, diarrhea, vomiting, nausea sometimes appear, which can stop abruptly.

Rash . This manifestation of the disease is called “exanthema”. A rash appears on the second day after the temperature rises. As a rule, it is localized on the neck, legs, arms, face, back, chest. Outwardly, it looks like small red dots on the skin, identical to the manifestation of measles. Sometimes the rash is localized in the mouth, throat, looks like bubbles filled with liquid, which then turn into sores.

Muscle pain . Enterovirus infection in some cases affects muscle tissue. It is localized more often in the chest, abdomen, much less often in the back, arms, legs. Deterioration of the condition is manifested by movement, the pain has a paroxysmal character. The duration can be several minutes and up to half an hour. If you do not start timely therapy, muscle pain will become chronic.

Diarrhea, vomiting. Often manifested in children under 2 years of age when the body is affected by an enterovirus infection. Sometimes the symptom is accompanied by bloating, pain. Diarrhea can last for several days. The main task of parents during this period is to restore fluid deficiency in time.

Additional symptoms of enterovirus infection:
drowsiness, lethargy;
abdominal pain;
loss of appetite;
swelling of the extremities;
general malaise;
dehydration;
conjunctivitis, redness of the eyes, lacrimation;
enlargement of the lymph nodes.

In healthy adults with strong immunity, enterovirus infection cannot develop to severe pathological processes, and most often it is completely asymptomatic, which cannot be said about young children, especially newborns and adults weakened by other diseases, such as HIV infection, oncological diseases, tuberculosis.

To prevent the disease of enterovirus infection, it is necessary to observe preventive measures:

Use guaranteed safe water and drinks (boiled water and drinks in factory packaging).
Eat foods that have been heat treated.
Thoroughly wash fruits and vegetables with safe water and then rinse with boiling water.
When swimming in ponds and pools, do not allow water to enter the oral cavity.

You should avoid visiting mass events, places with a large number of people (public transport, cinemas, etc.).
Wet cleaning of residential premises is recommended at least 2 times a day, ventilation of premises.

Under no circumstances should a child visit an organized children’s group (school, preschool institutions) with any manifestations of the disease. At the first signs of illness, you should immediately seek medical help, do not self-medicate!

Causes and treatment of diarrhea in adults

Translated from the Greek “diarrheo” means “I expire”. Anyone who has ever encountered this unpleasant problem should not explain the meaning of the word “diarrhea”. This syndrome causes a lot of inconvenience and unpleasant minutes and can be a symptom of serious diseases.

What is diarrhea?

Diarrhea – frequent loose stools (more than 3 times a day). A distinctive feature is watery stool, which is more than 90% consists of liquid.

Diarrhea is a syndrome, not a disease. It indicates that the body has experienced a malfunction in the gastrointestinal tract. With various diseases, diarrheal syndrome has its own distinctive features.

Causes of diarrhea

Diarrhea is a symptom of many diseases and pathological conditions of the gastrointestinal tract (GIT).

The most common causes of diarrhea are viral infections (rotaviruses, noroviruses, adenoviruses and others) or bacterial infections such as dysentery, salmonellosis and others.

But diarrhea can also develop under the influence of drugs, such as antibiotics, antiarrhythmic drugs. May be the result of an individual intolerance to a particular food product, the so-called food allergy. Diarrhea can be provoked by errors in the diet or the abuse of fatty, heavy foods. It accompanies a number of chronic diseases of the gastrointestinal tract (gastritis, pancreatitis, ulcers) or is a manifestation of irritable bowel syndrome.

But it is important to know that if we are talking about adults, then they most often have diarrhea as a result of poisoning with spoiled or low-quality products, the so-called food poisoning. Usually, food poisoning has a vivid clinical picture: in addition to frequent loose stools, vomiting, weakness, and fever with high body temperature are observed. Develops rapidly, lasts from 1 to 3 days.

Often diarrhea in adults occurs during travel, especially if it is a trip to exotic countries. There is even a special term – traveler’s diarrhea, it affects up to 30% of all tourists visiting exotic countries. Intestinal upset in this case is associated with changing climatic conditions, adaptation to new water, food, spices, stress due to the flight, or lower hygiene standards in a number of countries.

Why is diarrhea dangerous for adults?

Acute diarrhea in adults is dangerous because it can become chronic. In this case, loose stools haunt a person every day for a month or more. This significantly affects the general well-being of a person, his performance, immunity and, of course, the quality of life. In this case, it is necessary to consult a doctor and undergo a comprehensive examination and treatment. Find out the cause of diarrhea and eliminate it!

Diarrhea is also dangerous due to the development of such complications as:
– Dehydration.
– Cardiac arrhythmias, convulsions, muscle pain.
– Cachexia – a state of extreme exhaustion of the body.

Help with diarrhea in adults

It is better to start treating diarrhea as soon as you understand that loose stools are not an isolated case. Depending on the causes of diarrhea, the doctor will prescribe a complex treatment, but here are the general rules that should be followed by all patients with diarrhea.

1. Start antidiarrheal drugs

Treatment should begin with drugs that have antidiarrheal activity, that is, they are ways to stop diarrhea. There are a huge number of antidiarrheals, but your choice should be on the one that is not only effective, but also safe. It is to such means that Adiarin belongs. This product is based on a fundamentally new active ingredient – tannat gelatin, which not only acts quickly and stops diarrhea, but also protects the intestines from the aggressive effects of the factors that provoked it (viruses, toxins, bacteria). It creates a special protective bio-barrier on the damaged mucous membrane of the small intestine, which stops inflammation, restores the integrity of the intestinal epithelium and normalizes its physiological functions, preventing the development of dehydration. In this case, the drug works only in the intestines and has no effect on the body as a whole.
After improving the condition and reducing the frequency of loose stools, it is the turn of enzyme preparations and probiotics. They help to restore the microflora and restore the ability of the stomach and intestines to function normally.

2. Drink more fluids

Diarrhea causes the body to lose a lot of water and electrolytes. You can make up for the lack of fluid with an enhanced water regime, but special rehydration solutions cope best with dehydration, because they contain the necessary salts and trace elements.

3. Keep a sparing diet

All “irritants” must be excluded from the diet: spicy, salty, sour, coarse fiber.
