What is persistent low grade fever? What causes persistent low grade fever?

A hypothermia with a body temperature higher than normal but below 38 degrees Celsius is called a low-grade fever. The low-grade fever referred to in TCM also includes the patient's subjective enthusiasm in the hands and feet, and the heat in the chest without the body temperature being higher than normal. The common manifestations are hot and cold at night, or fever at night, hot flashes in the afternoon, hot hearts and hands, evaporative fever from the bones, often accompanied by symptoms and signs such as weight loss, fatigue, fatigue, anorexia, irritability, red tongue and less lichen, and thin pulse.

Modern medicine divides this disease into two categories: infectious and non-infectious. Long-term low-grade fever (lasting more than 2 weeks) is common in pediatric tuberculosis and extrapulmonary tuberculosis; Chronic infection lesions (such as chronic tonsillitis, chronic paranasal sinusitis, chronic gingivitis, chronic otitis media, chronic nephritis, etc.); Functional low-grade fever, characterized by a normal body temperature in the early morning and low-grade fever after activity.

Based on the clinical presentation, diagnosis is not difficult in patients with low-grade fever as the main symptom. The key is to find out the best and judge the causes.

Modern medicine mainly adopts the method of eliminating this disease.

The medicine of the motherland believes that external evil invades the human body, and the conflict between good and evil can cause fever; Fatigue from eating, emotional stagnation, food and lodging, phlegm drinking, blood stasis, etc., which can lead to dysfunction of the viscera, loss of qi, blood and fluid, imbalance of yin and yang, and can cause fever; Deficiency of qi, blood, yin, and yang can cause fever. In the case of this disease, there are usually more internal injuries than external injuries.

Among children with low-grade fever, there are many cases that are difficult to find out for a while, and traditional Chinese medicine can be used.

Clinical efficacy] 1960 cases of this disease were treated with pure Chinese medicine**, all of them**, and the average body temperature returned to normal after taking 2 doses.

Reverse fever, the maximum body temperature does not exceed 39 degrees Celsius, and it persists for more than a month and does not improve, which can be defined as "persistent low-grade fever".

Diagnosed with Mycoplasma pneumoniae infection, using erythromycin antibiotics ** for 19 days, antibiotics should be sufficient, I don't think there is any need to use antibiotics anymore. The use of antibiotics is regulated and cannot be abused, otherwise it will cause serious consequences (such as dysbiosis, fungal infection, etc.).

The current situation is that there is no abnormality in the heart and lungs on chest x-ray (indicating that the local inflammation of the lungs has disappeared), but there is a low fever in the afternoon or evening every day, and occasionally a low fever in the morning. It may be a post-respiratory syndrome, please refer to a Chinese medicine doctor for conditioning, cold repellent, etc., and good results will be obtained.

Persistent low-grade fever refers to a fever that lasts for more than two weeks and has a temperature in between, and persistent low-grade fever is caused by the following causes:

1. Infectious diseases. Tuberculosis infection is the most common among all infectious persistent low-grade fevers, such as pulmonary tuberculosis, which can be accompanied by long-term night sweats, cough, sputum production, hemoptysis, weight loss and other symptoms.

2. Chronic inflammation. For example, chronic pelvic inflammatory disease, chronic otitis media, chronic tonsillitis, chronic sinusitis, chronic pyelonephritis, etc.

3. CMV infection can also cause persistent low-grade fever.

Fourth, non-infectious diseases. Such as hyperthyroidism, rheumatic fever, systemic lupus erythematosus, hematologic diseases such as leukemia, aplastic anemia, lung cancer, liver cancer, bowel cancer and other neoplastic diseases can cause persistent low-grade fever.

5. Drug fever after taking or injecting drugs can also cause persistent low-grade fever.

6. Functional persistent low-grade fever, including physiological, seasonal, environmental, and neurological disorders.

1. Persistent low-grade fever after infection.

Persistent low-grade fever occurs when the central body temperature regulation function has not been restored after the acute infectious disease has passed.

2. Post-streptococcal infection.

Many patients have persistent low-grade fever after respiratory tract infection, and the blood sedimentation rate is accelerated during blood test, and the symptoms can be quickly relieved under salicylic acid, penicillin, and low-dose adrenocorticosteroid**, which is called the post-streptococcal infection state.

3. Organic low fever.

Just like tuberculous low-grade fever and the presence of chronic foci of infection. Other diseases include hyperthyroidism, tumors, leukemia, and so on.

We know that there are many causes of persistent low-grade fever, but what should we do if it persists?

1. Replenish water appropriately.

When we have a low-grade fever, because we are warm, the body sweats, and then the heat is released to the outside of the body, if the water in the body is lost, and the water is not replenished in time, the fever is even more difficult to retreat. Therefore, it is very important to stay hydrated.

2. Supplementation of nutrition is very important.

Many people think that sick stomach and intestines have poor digestion, so it is good to eat simple. As everyone knows, patients with low-grade fever also need nutritional supplements, such as rice soup, clear soup or milk, and timely supplement protein-rich foods such as fish, meat, and eggs. You can also eat more fruits and vegetables to improve your immunity.

3. Sleep on ice pillows and warm water wipes.

Low-grade fever is also a type of fever, and patients can sleep on ice pillows, and then rub their body with warm water, several times, so that the body temperature can return to normal body temperature.

4. Change your clothes frequently.

Patients should change their clothes frequently, because there are bacteria on their clothes, so they should move quickly when changing clothes, so that they do not let their bodies catch cold again, and keep warm in the room.

5. Pay attention to symptoms such as constipation and trembling.

A variety of illnesses can cause low-grade fever. Fever is a symptom that diseases such as rheumatism, tuberculosis, chronic inflammation, and low immunity can cause persistent low-grade fever; Long-term psychological stress and emotional instability can also cause disorders in the body temperature center, resulting in unexplained persistent low-grade fever. Problems with any of the body's systems can cause a persistent low-grade fever.

The cause of low-grade fever is difficult to detect through routine tests such as blood, urine, and stool, and some low-grade fever caused by bacterial infections can only be detected through bacterial culture.

Unknown low-grade fever should not be abused. Fever is one of the body's reactions to the invasion of disease. Patients with low-grade fever take antipyretics, which is not conducive to the disease**.

Indiscriminate use of antipyretics can also lead to a decrease in white blood cells and aplastic anemia. Antipyretics should only be considered if the temperature is above 38.

Persistent low-grade fever should be treated as soon as possible, and a thorough examination should be done as soon as possible. Some symptoms of early malignancy or early bacterial infection are also low-grade fever. It is recommended that you go to the hospital for relevant examinations to avoid the worsening of the fever**.

High fever is one of the mechanisms by which the body fights infection. By raising body temperature, our body mobilizes its own defense system to kill foreign germs (in general, germs die at 39 or more), thereby shortening the duration of illness and enhancing the effectiveness of antibiotics. If you use medication to reduce the fever at the beginning of a cold (37-38 5), it will temporarily turn the bacteria in your body into a state of suspended animation, and make them resistant to the antibiotics, which is often more difficult once it returns**.

Long-term persistent low-grade fever is dangerous and is likely to be caused by some serious illness, such as tuberculosis, rheumatic fever, hyperthyroidism and anemia. However, sometimes a low-grade fever may be physiologically high. If you have a long-term low-grade fever, you need to check the blood count, chest x-ray, erythrocyte sedimentation rate, anti-chain O, rheumatoid factor, and thyroid function to determine the cause.

If it is anemia as a blood supplement**, tuberculosis can go to the tuberculosis prevention center to receive free anti-tuberculosis drugs**, and hyperthyroidism can use drugs such as propylthiouracil**.

If you continue to have a low-grade fever, you need to go to a local hospital for **, to detect whether the low-grade fever is caused by physical health problems, it is recommended to perform a blood routine and mycoplasma test to confirm that it is a viral infection, bacterial infection or mycoplasma infection, and give antiviral, antibacterial, etc. according to the results of the examination**. In addition, inflammation of the tonsils may also cause persistent low-grade fever, and if recurrent infections occur for a long time, surgical removal may be considered.

Good afternoon high fever is generally inflammation, for people, there is no big problem. However, low-grade fever is generally very serious, and it is a major problem in the body, so it is recommended to go to the hospital for examination as soon as possible.

Persistent low-grade fever is a pathological low-grade fever caused by a disease, which has the characteristics of being complex, lasting for a long time and having obvious symptoms. He also had a low-grade fever that persisted after bacteria, viruses or parasites infected the human body.

Hello, persistent low-grade fever may be inflammation in some parts of the body or a decrease in the body's immunity.

This is because the resistance is too weak, and the environment is hot and cold, which will lead to intermittent low-grade fever in the world, which is still very serious, and it is still necessary to be active.

This is because the body is infected with a virus and because the body has entered the bacteria, so if this happens, you must go to the hospital for a routine blood test.

It may be due to chronic inflammation, tuberculosis, or a viral infection.

Hello, low-grade fever refers to fluctuations in body temperature between. First of all, it is considered infectious low-grade fever, which is also the most common disease that causes fever, such as tuberculosis infection, bacterial infection, viral infection, etc. If the fever is low-grade due to these reasons, routine blood tests can be considered, and if the leukocytes are elevated and the neutrophil ratio is elevated, a bacterial infection is considered.

If lymphatic count is elevated, a viral infection is considered. In patients with bacterial infection, anti-inflammatory drugs such as penicillin amoxicillin, cefnicesi, cefoxitin, cefoxitin, and quinolone ofloxacin may be considered. For viral infection, the most commonly used drugs are mainly ribavirin, oseltamivir, etc.

Low fever, also known as low fever, is a common symptom, generally we talk about low fever refers to body temperature more than normal, refers to body temperature, long-term low fever refers to a continuous fever for more than two weeks, excluding intermittent fever. Persistent low-grade fever should be treated as soon as possible, and a thorough examination should be done as soon as possible. Some symptoms of early malignancy or early bacterial infection are also low-grade fever.

Persistent low-grade fever can be caused by the following reasons: 1. Post-infection low-grade fever: Seen after recovery from acute infectious diseases, a small number of patients still have low-grade fever for several weeks, which is related to the recovery of the central function of body temperature regulation.

2. Post-streptococcal infection state: After suffering from respiratory tract infection, persistent low-grade fever can occur, during blood test, anti-"O" titer increases, blood sedimentation rate is accelerated, with penicillin, salicylic acid and low-dose adrenocorticosteroid **, the symptoms are quickly relieved, and the low-grade fever of this phenomenon is called the post-streptococcal infection state. 3. Organic low fever.

For example, tuberculous low-grade fever and chronic lesion infection (such as sinuses, tonsils, hepatobiliary, urinary system, etc.). Other diseases such as hyperthyroidism, connective tissue, tumors, leukemia, etc.

According to the situation you described, it is mainly considered to be a symptom of upper respiratory tract infection caused by a virus, commonly known as a cold, the common symptoms are fever, cough, runny nose or nasal congestion and other symptoms, viral infection accounts for 80%, Suggestions: It is recommended that you use anti-inflammatory drugs with Qingkailing or Yan Huning and other heat-clearing and detoxifying drugs to work better, the characteristic of viral infection is that it is easy to repeat high fever, the virus will generally stop replicating in a week, don't be too nervous, drink more boiled water, pay attention to rest, oral VC Tylenol If the body temperature is higher than that, you can take a cold compress on the forehead to physically cool down, and if the temperature is higher, you can use fever-reducing drugs.
