What are the common causes of persistent low grade fever. How can you identify symptoms of low grade fever. What treatments are available for persistent low grade fever.

Understanding Low Grade Fever: Definition and Characteristics

A low grade fever is characterized by a slight elevation in body temperature, typically ranging between 100.5°F and 102.2°F. When this temperature range persists for more than two weeks, it is considered a persistent low grade fever. While the average human body temperature is around 98.6°F, it’s important to note that this can fluctuate throughout the day.

Persistent low grade fevers often indicate that the body is actively fighting an infection or dealing with an underlying health issue. The elevated temperature is a natural defense mechanism employed by the immune system to combat pathogens and restore health.

Recognizing Symptoms of Low Grade Fever

While some individuals may barely notice a low grade fever, others might experience a range of symptoms. These can include:

• Feeling warm to the touch
• Sweating
• Chills or shivering
• Headaches
• Muscle aches
• Dehydration
• General malaise or feeling unwell

Is it possible to have a low grade fever without noticeable symptoms. Yes, some individuals may have an elevated body temperature without experiencing any other obvious signs of illness. This is why regular temperature monitoring can be crucial in identifying persistent low grade fevers.

Common Causes of Persistent Low Grade Fever

Persistent low grade fevers can stem from various underlying conditions. Understanding these potential causes is essential for proper diagnosis and treatment.

Respiratory Infections

Respiratory infections are frequently associated with low grade fevers. Common culprits include:

• Common cold
• Influenza (flu)
• Upper respiratory tract infections

These infections often present with additional symptoms such as coughing, sneezing, nasal congestion, sore throat, and fatigue. In many cases, these infections resolve on their own with proper rest and hydration.

Urinary Tract Infections (UTIs)

UTIs can cause persistent low grade fevers along with other symptoms like:

• Abdominal pain
• Burning sensation during urination
• Frequent urination
• Cloudy or dark urine

UTIs typically require antibiotic treatment prescribed by a healthcare professional. Prompt medical attention is crucial to prevent the infection from spreading to the kidneys.

Less Common Causes of Persistent Low Grade Fever

While respiratory infections and UTIs are frequent culprits, several other conditions can lead to persistent low grade fevers.

Medication Side Effects

Can medications cause persistent low grade fevers. Yes, certain medications may induce low grade fevers as a side effect. This type of fever typically subsides within 72 hours of discontinuing the medication. It’s essential to consult with a healthcare provider before stopping any prescribed medications.

Chronic Stress

Surprisingly, chronic stress can manifest as a low grade fever, particularly in young women. This phenomenon, sometimes referred to as “psychogenic fever,” underscores the intricate connection between mental health and physical well-being.

Rare Cases: Cancer

In rare instances, a persistent low grade fever with no apparent cause may be a sign of certain cancers, such as:

• Leukemia
• Hodgkin’s lymphoma
• Non-Hodgkin’s lymphoma

These conditions often present with additional symptoms like persistent fatigue, unexplained weight loss, and night sweats. It’s crucial to consult a healthcare professional if experiencing these symptoms alongside a persistent fever.

Diagnosing the Cause of Persistent Low Grade Fever

Identifying the underlying cause of a persistent low grade fever often requires a thorough medical evaluation. Healthcare providers typically employ a combination of methods to reach a diagnosis.

Medical History and Physical Examination

The diagnostic process usually begins with a comprehensive review of the patient’s medical history and a physical examination. The healthcare provider will inquire about:

• Duration and pattern of the fever
• Associated symptoms
• Recent travel history
• Exposure to potential pathogens
• Current medications

How does a physical examination help in diagnosing the cause of a low grade fever. A thorough physical exam can reveal important clues such as signs of infection, inflammation, or other underlying conditions that may be contributing to the fever.

Laboratory Tests

Various laboratory tests may be ordered to help identify the cause of a persistent low grade fever:

• Complete blood count (CBC)
• C-reactive protein (CRP) test
• Erythrocyte sedimentation rate (ESR)
• Blood cultures
• Urinalysis

These tests can provide valuable information about potential infections, inflammatory conditions, or other abnormalities that may be causing the fever.

Imaging Studies

In some cases, imaging studies may be necessary to identify the source of a persistent low grade fever. These may include:

• Chest X-rays
• Computed tomography (CT) scans
• Magnetic resonance imaging (MRI)

Imaging studies can help detect hidden infections, tumors, or other structural abnormalities that may be contributing to the fever.

Treatment Approaches for Persistent Low Grade Fever

The treatment of persistent low grade fever largely depends on its underlying cause. Once a diagnosis is established, healthcare providers can recommend appropriate interventions.

Treating Underlying Infections

For infectious causes, such as respiratory infections or UTIs, treatment typically involves:

• Antibiotics for bacterial infections
• Antiviral medications for certain viral infections
• Supportive care, including rest and hydration

It’s crucial to complete the full course of prescribed antibiotics, even if symptoms improve, to prevent the development of antibiotic-resistant bacteria.

Managing Medication-Induced Fevers

If a medication is suspected to be the cause of the fever, the healthcare provider may recommend:

• Discontinuing the medication (if safe to do so)
• Switching to an alternative medication
• Adjusting the dosage

Never stop taking prescribed medications without consulting a healthcare professional, as abrupt discontinuation can sometimes lead to serious consequences.

Addressing Stress-Related Fevers

For fevers related to chronic stress, treatment may involve:

• Stress reduction techniques (e.g., meditation, yoga)
• Cognitive-behavioral therapy
• Lifestyle modifications
• Medications to manage anxiety or depression, if necessary

How effective are stress reduction techniques in managing stress-related fevers. Many individuals find significant relief from stress-related symptoms, including low grade fevers, through consistent practice of stress reduction techniques. However, results can vary, and it’s important to work with a healthcare provider to develop a comprehensive management plan.

When to Seek Medical Attention for a Persistent Low Grade Fever

While low grade fevers are often not cause for immediate concern, certain situations warrant prompt medical attention.

Red Flags to Watch For

Seek medical care if a persistent low grade fever is accompanied by:

• Severe headache
• Stiff neck
• Confusion or altered mental state
• Difficulty breathing
• Severe abdominal pain
• Unusual rashes
• Persistent vomiting

These symptoms could indicate a more serious underlying condition that requires immediate medical intervention.

Monitoring Fever in Special Populations

Certain groups should be particularly vigilant about persistent low grade fevers:

• Infants and young children
• Elderly individuals
• Pregnant women
• People with compromised immune systems
• Individuals with chronic medical conditions

For these populations, even a low grade fever can sometimes indicate a serious problem, and medical advice should be sought promptly.

Prevention and Self-Care Strategies for Low Grade Fever

While not all causes of persistent low grade fever are preventable, certain strategies can help reduce the risk and manage symptoms.

Boosting Immune Function

A strong immune system is crucial in fighting off infections that may cause low grade fevers. To support immune function:

• Maintain a balanced diet rich in fruits, vegetables, and whole grains
• Stay adequately hydrated
• Get regular exercise

• Manage stress levels
• Consider supplements like vitamin C and zinc (consult with a healthcare provider first)

How does diet impact immune function and fever prevention. A nutritious diet provides essential vitamins, minerals, and antioxidants that support optimal immune function, potentially reducing the likelihood of infections that can cause fevers.

Practicing Good Hygiene

Proper hygiene habits can significantly reduce the risk of infections:

• Wash hands frequently with soap and water
• Use hand sanitizer when soap and water are unavailable
• Avoid touching face, especially eyes, nose, and mouth
• Cover mouth and nose when coughing or sneezing
• Clean and disinfect frequently touched surfaces

These practices help prevent the spread of pathogens that can cause infections and subsequent fevers.

Managing Chronic Stress

Given the potential link between chronic stress and low grade fevers, implementing stress management techniques can be beneficial:

• Practice mindfulness or meditation
• Engage in regular physical activity
• Maintain social connections
• Pursue hobbies and enjoyable activities
• Consider professional counseling if stress becomes overwhelming

Effective stress management not only potentially reduces the risk of stress-related fevers but also contributes to overall health and well-being.

Understanding the Impact of Persistent Low Grade Fever on Daily Life

Living with a persistent low grade fever can significantly affect an individual’s quality of life. It’s important to recognize these impacts and develop strategies to cope effectively.

Effects on Work and Productivity

A persistent low grade fever can impact work performance and productivity in several ways:

Share on PinterestIf the body is fighting off an infection, a person may experience a persistent low grade fever.

Some people may hardly notice that they have a low grade fever. However, others may experience various symptoms, including:

• feeling warm to the touch
• sweating
• chills
• shivering
• headaches
• muscle aches
• dehydration
• a general feeling of being unwell

A persistent low grade fever is typically a sign that the body is fighting off an infection or another health issue and has raised its temperature to help these efforts.

These underlying issues can include:

Respiratory infections

Respiratory infections can cause a persistent low grade fever. Some of the most common respiratory infections, such as a cold or the flu, may cause a low grade fever that lasts for as long as the body takes to fight off the infection.

Other symptoms that may indicate a respiratory infection include:

• coughing
• sneezing
• a stuffy or runny nose
• a sore throat
• chills
• general fatigue
• lack of appetite

Many simple respiratory infections do not require treatment, and the symptoms will go away in time.

Urinary tract infections

A urinary tract infection (UTI) may also be the underlying cause of a low grade fever. A UTI is a bacterial infection that occurs when bacteria multiply anywhere in the urinary tract, which includes the bladder, urethra, kidneys, and ureters.

In addition to a low grade fever, the person may experience symptoms such as:

• pain in the abdomen
• a burning sensation while peeing
• frequent urination
• a constant urge to urinate
• dark urine

Most UTIs are simple to treat with antibiotics. The doctor may analyze a urine sample to determine the precise type of bacteria causing the infection to ensure that they prescribe the right treatment.

Other infections

Share on PinterestA person should talk to their doctor if they experience any symptoms of infection alongside a fever.

Almost any infection can cause a fever. A fever is one of the body’s natural responses to foreign invaders. The body may keep its core temperature elevated while it is fighting off the infection.

Other sources of infections that may cause a low grade fever include:

• food poisoning
• exposure to pathogens from livestock
• tuberculosis
• meningitis

Anyone experiencing symptoms of infection alongside a fever should see a doctor if the symptoms do not improve with rest and time.

Medications

Some medications can cause many different side effects, which may include a low grade fever. People can check the information on side effects and interactions that comes in the packaging or seek advice from a pharmacist.

As the author of a 2018 review notes, if the medication is the cause, the fever should go away very quickly — typically within 72 hours — once the person stops taking the drug.

Stress

Chronic stress may cause a low grade fever. A research paper from 2015 notes that a fever due to stress is most common in young women.

Reducing stress levels may resolve the fever in these cases.

Cancer

In rare cases, a persistent low grade fever with no known cause may be a sign of cancer.

A persistent fever can be a symptom of leukemia, Hodgkin disease, or non-Hodgkin lymphoma.

The person may also experience other symptoms of cancer, including:

• persistent fatigue
• weakness
• headaches
• infections
• lack of appetite
• excessive bruising or bleeding
• unexplained weight loss
• enlarged lymph nodes
• excessive sweating at night

Many of these symptoms are not unique to cancer, however.

Anyone who experiences these symptoms along with a low grade fever should see a doctor for a diagnosis.

Chronic disorders

Many other chronic disorders may cause symptoms such as a low grade fever, including:

• thromboembolic disease
• arthritis
• lupus
• gout
• thyroiditis
• serum sickness-like reactions
• serotonin syndrome
• neuroleptic malignant syndrome

Diagnosing a persistent low grade fever may involve several different tests to eliminate potential causes.

The doctor will generally carry out a physical examination and question the person regarding additional symptoms and whether they have any chronic conditions.

The doctor may also ask about any medications that the person takes so that they can eliminate them as a cause of the fever.

They may order blood tests, such as a complete blood count (CBC), to get an overview of the person’s health. The results may help them decide which other tests, if any, they need to order.

If the doctor suspects that the person has a UTI, they may ask them for a sample of their urine to test.

Share on PinterestOTC drugs may help treat a low grade fever at home.

Treatment for a persistent low grade fever will depend on the cause. For instance, minor infections may not need treatment at all, whereas issues such as cancer require extensive treatment.

To alleviate the symptoms of a low grade fever at home, a person can try over-the-counter (OTC) drugs, such as ibuprofen (Advil) or acetaminophen (Tylenol).

A fever can cause dehydration, so it is vital to drink plenty of water.

It is important to treat a low grade fever in children, who may be more sensitive to temperature changes. Using children’s versions of OTC drugs may help control the fever while waiting to see a doctor.

A persistent low grade fever is a sign of an underlying issue, such as a mild infection or chronic condition. The fever may persist while the person is fighting off the infection.

For the most part, persistent low grade fevers are not a cause for concern. However, it is important to monitor the fever to see whether it gets worse.

Anyone who is concerned about their symptoms or experiences a persistent low grade fever for more than 10 days should see a doctor.

causes and what is subfebrile temperature

01/29/2020Updated 07/14/2021

The normal average body temperature is 36.6°C degrees Celsius. If the deviation on the temperature scale exceeds 0.5 ° C, in one direction or the other, this is not a critical indicator.

However, if the body temperature systematically rises to 37.1°C for no apparent reason, this is a reason to go to the doctor for a detailed clarification of the circumstances.

Usually, subfebrile temperature is called when the mark on the thermometer rises to 38 ° C and stays at this border. And often this is a temperature of 37.1 ° C.

In fact, an increase in body temperature does not occur from scratch.

The leading therapist of the R + Medical Network private clinic will tell you how to recognize subfebrile temperature and what are the most common reasons for this in medical practice.

Despite the fact that the causes of low-grade fever can be very different. Our doctors will still try to detail and convey the most important information to you so that you can pay attention to the hidden symptoms of the pathology in a timely manner and seek medical help. Usually, subfebrile temperature is called when the mark on the thermometer rises to 38 ° C and stays at this border. And often this is a temperature of 37.1 ° C.

What is subfebrile temperature?

Being informed is important. Especially when it comes to your own well-being or the health of loved ones.

So, body temperature can change throughout the day, depending on how you feel, climatic conditions, time of day. Therefore, deviations in the temperature regime of 0.5-1°C are not considered a pathology.

Therefore, if the temperature of 37.1°C lasts for a long period, then it returns to normal, and then rises again – sign up for a consultation with a specialist. Since the real problem can be detected only after a thorough diagnosis of the body.

Causes of subfebrile temperature can be identified using a complete blood count, fluorography, ultrasound, MRI, etc. Therefore, if the temperature of 37.1 ° C lasts for a long period, then returns to normal, and then rises again – sign up for a consultation with specialist. Since the real problem can be detected only after a thorough diagnosis of the body.

An increase in temperature is most often an immune reaction to an inflammatory process in the body or an infection.

Thus, the immune system is actively involved in the fight against the “enemy” and signals that a failure has occurred. A virus or a focus of the inflammatory process has appeared in the body.

Therefore, it is very important not to delay the visit to the doctor, but to do it as soon as possible at the first signs of the disease. After all, any disease is always easier to prevent than to treat in the last stages of pathology.

The main causes of subfebrile temperature

The most common reasons why the body can give temperature alarms are:

1. Anemia.
2. Intestinal parasites
3. Tuberculosis.
4. AIDS/HIV.
5. Toxoplasmosis, sepsis.
6. Oncological diseases.
7. Diseases of the thyroid gland.
8. Viral hepatitis, intestinal infection.
9. Autoimmune diseases (allergies, arthritis, ulcerative colitis, rheumatism).
10. Hormonal imbalance (in pregnant women, as a variant of the norm).

By the way, the causes of a temperature of 37 ° C in women may well lie in the natural ovulation period, so if you are approaching or having your period, you should not worry about this.

Subfebrile temperature in a child. What to do?

If a subfebrile temperature is observed in a teenager or a small child, first and foremost, make sure that this is not a “temperature tail” (the result of a cold or a viral illness).

Many parents start to panic when their child has a temperature of 37°C, but they forget that the child has just recently had a cold, flu or a sore throat.

After ARVI, a child may have subfebrile temperature for 5-14 days. And that would be the norm.

However, if the child has a subfebrile temperature and cannot explain his condition to you, it is important to contact a competent doctor who will diagnose and determine the exact cause of the temperature increase for further correct treatment.

Normal temperature range for people of different ages

These temperature ranges can be observed in most people of all ages. Balancing these boundaries remains the norm if the temperature changes under the influence of external factors or characteristics of the organism (this should be clarified with the doctor).

However, if low-grade fever causes discomfort or is accompanied by symptoms of an unknown etiology, your task is to find the cause as soon as possible and begin effective treatment.

R+Medical Network premium class private clinic in Goloseevsky and Pechersky districts of Kiev is distinguished by the fact that we provide patients with an integrated approach to both diagnosis and treatment of diseases.

We are not satisfied with a single indicator of tests, we are interested in a detailed analysis of the root cause of subfebrile temperature and its immediate elimination .

Subfebrile temperature – what is dangerous? What to do? Where to go in Kazan? MC Health Formula

36.6 is not a constant body temperature of a healthy person, if you monitor it during the day, then this value will fluctuate slightly. The lowest result, about 36 degrees, will be at the time of morning sleep. If a person is hot after exercise, the temperature may rise slightly

Body temperature is affected by heat, humidity, too warm clothes. In women, there is a slight jump in temperature (by half a degree) on certain days of the menstrual cycle. But it will be a one-time increase. A cause for concern may be an increase in temperature from 37.2 to 37.9 for a period of more than a month – this is subfebrile temperature.

If subfebrile temperature lasts for more than two weeks, and it is accompanied by symptoms such as fatigue, poor sleep, shortness of breath, then the therapist should not be postponed. Often, low-grade fever signals a malfunction in the body when other symptoms have not yet appeared.

Causes of subfebrile temperature

There are diseases that provoke a slight increase in temperature over a long period.

• Chronic infectious process (tuberculosis, chronic diseases of the nasopharynx, pancreatitis, cholecystitis, prostatitis, adnexitis, bacterial endocarditis, chlamydia, syphilis, HIV infection).
• Inflammatory process
• Oncology
• Autoimmune diseases (rheumatism, ulcerative colitis, drug allergy, arthritis, postinfarction syndrome)
• Parasites
• Pathologies of the endocrine system (thyrotoxicosis, severe menopause)
• Thermoneurosis (vegetative dysfunction affecting heat transfer)

If the cause of fever is an infection, then it is characterized by:

• decrease after taking antipyretic;
• poor tolerance;
• there are fluctuations throughout the day.

But there are reasons when a healthy person has a subfebrile temperature:

• overheated
• under stress
• when taking certain drugs
• hereditary factor when a child is born and lives with a fever
• with activation of the hypothalamus
• during pregnancy
• before menses.

Such a temperature is not amenable to the action of antipyretic drugs, is easily tolerated and does not have pronounced daily fluctuations.

Examination will help to find out the cause.

Analyzes and studies at subfebrile temperature.

You should always start with a general practitioner. It is the general practitioner who will refer you for primary tests, and then, after the results obtained, will recommend the appointment of a narrow specialist: an endocrinologist, a cardiologist, a gynecologist, an otolaryngologist, an infectious disease specialist.

Fever for more than two weeks?

Need to submit:

• General analysis of blood and urine (increased leukocytosis, protein in the urine)
• Blood for hepatitis B and C, HIV and syphilis
• Sputum culture for Mycobacterium tuberculosis
• Urine culture (genital infections) and blood culture (sepsis).

Do:

• Chest x-ray (tuberculosis, lung abscess)
• Electrocardiogram (bacterial endocarditis)
• Pelvic ultrasound (inflammatory diseases)
• Abdominal ultrasound

If, after the results obtained, the cause is not established, then the patient is sent to take a blood test:

• for hormones
• for rheumatoid factor
• for tumor markers.
