What causes frequent fever

In fact, a high fever has a great impact on the body, so you must pay attention to what causes a high fever so that you can prevent it correctly. For example, whether it is a dietary problem or some problems with low immunity can easily cause a fever.

1. Fever is caused by the rapid increase of white blood cells in the body in order to devour bacteria, which increases oxygen consumption and causes fever. Although a body temperature of 37C is a normal value, this number is not a fixed value. "Normal body temperature is different for everyone and can fluctuate greatly throughout the day. Food, excessive clothing, emotional excitement, and intense exercise can all raise body temperature.

2. Fever itself is not a disease, but a symptom. In fact, it is one of the body's mechanisms for fighting infection. Fever may even have its uses: shortening the duration of illness, enhancing the effectiveness of antibiotics, and making infections less contagious. These abilities should offset the discomfort experienced when having a fever.

3. The etiology diagnosis of fever of unknown origin (FUO) is a global problem, and the cause of nearly 10% of FUO cases remains unknown. Fever itself can be caused by many types of diseases, such as infection, tumors, autoimmune diseases and blood diseases, and cannot be clearly classified. In the past, such patients were usually diagnosed and treated by internal medicine physicians, and in most hospitals with more specialized specialties, they were mainly treated by respiratory physicians.

4. Currently, many hospitals have opened infection departments and FUO is classified as being diagnosed and treated by the infection departments. This specialized management is an improvement and can improve the level of diagnosis and treatment. FUO has an accurate definition, which includes three key points: ① fever lasts for ≥3 weeks; ② body temperature is >38.3℃ for multiple times; ③ the diagnosis cannot be confirmed after ≥1 week of complete medical history, physical examination and routine laboratory tests. It can be seen that although FUO itself is a symptom diagnosis rather than a disease diagnosis, the diagnostic requirements are very strict.
