What disease may cause repeated low-grade fever?

As the name suggests, low fever means that although the human body has a fever, that is, the temperature is higher than the normal temperature, but it is below 38 degrees. As we all know, the normal temperature of the human body is 37 degrees. If it exceeds this temperature, it is a fever. Below 38 degrees, above 37 degrees can be called low fever, which is a common symptom. Clinically, it is believed that various diseases may cause low fever, so once the low fever lasts for more than two weeks, it is best to go to the hospital for timely treatment.

1. Pay attention to replenishing sufficient water

Continuous fever is due to the loss of the ability to regulate body temperature. Fever can easily consume physical strength, so good care is needed. In terms of diet, more nutritious foods should be added and easily digestible foods should be eaten. Since patients will urinate a lot when they have a fever, the water in the body will also be lost, so sufficient water should be added. A variety of illnesses can cause a low-grade fever. Fever is a symptom. Diseases such as rheumatism, tuberculosis, chronic inflammation, and low immunity can cause persistent low fever. Long-term psychological stress and emotional instability can also cause disorders in the body temperature center, resulting in persistent low fever of unknown cause. A problem with any system in the body can cause a persistent low-grade fever.

2. Temporarily apply ice

Heat is mainly transferred through the exchange of heat between ice placed in large blood vessels throughout the body and the flowing blood. At the same time, it can reduce the oxygen consumption of brain cells, delay brain cell damage, and is beneficial to the body's microcirculation. Put homemade ice cubes just taken out of the refrigerator into a plastic bag, tie it tightly, put it in 2-3 layers to prevent leakage, and then wrap a towel on the outside. Apply ice packs to the back of the head, forehead, armpits, neck, groin and other places where large blood vessels pass. Change it every 5-10 minutes until the high fever subsides.

Then wrap a towel around it.

3. Do not abuse drugs and seek medical treatment as soon as possible

Do not abuse medicine for unexplained low-grade fever. Fever is one of the body's responses to disease. Taking antipyretics for patients with low fever is not conducive to the treatment of the disease. Indiscriminate use of antipyretics may also lead to a decrease in white blood cells and aplastic anemia. Antipyretics should only be considered when the body temperature is above 38°C. If a low-grade fever persists, you should seek medical attention as soon as possible and undergo a comprehensive examination. Some early symptoms of malignant tumors or bacterial infections are also low-grade fever. Long-term low-grade fever is commonly caused by tuberculosis infection. Tuberculosis is relatively common in children. In addition to low-grade fever, children may also experience changes in personality.

How to prevent a low-grade fever

1. Add or remove clothes appropriately

Colds and fevers often occur when the seasons change. To prevent low-grade fever, we need to pay attention to adding or removing clothes in time according to the ambient temperature to maintain normal body temperature.

2. Wash your face with cold water more often

Washing your face with cold water can stimulate the blood vessels in the skin and enhance the body's ability to resist cold and prevent diseases. And when you go to bed at night, you must open the windows. This can not only keep the indoor air fresh, but also allow the cold air at night to enter the room to enhance the body's ability to adapt to the cold environment, which is also beneficial for prevention.

3. Nutrition should be balanced

If immunoglobulins are deficient, the body's ability to resist bacteria or viruses will decrease. Fish, meat, eggs, milk and soy products have high nutritional value and should be consumed carefully to enhance the synthesis and utilization of protein. In addition, taking vitamin C and foods rich in vitamin C also plays a certain role in prevention.

4. Supplement appropriate enzymes

There are many bacteria in the human body, both beneficial and harmful. When harmful bacteria dominate, the body's immunity and resistance decrease, leading to colds. Appropriate supplementation of certain longevity enzymes in normal times can help prevent colds.

5. Do some exercise regularly

Physical exercise and balanced nutrition are equally important, so you should exercise more often, such as running, doing exercises, etc. Taking more walks outdoors in the morning and evening and breathing fresh air can enhance blood circulation, improve physical fitness, and enhance immune function.
