Children have low fever during the day and high fever at night

Many people think that fever is a disease. Fever is not a disease but a symptom. It reminds us that there is a problem with our body. There are many reasons for fever. Some body temperatures are higher than normal, which is called a high fever. Others are lower than normal, which is called a low fever. Some children have a low fever during the day and a high fever at night. What is going on?

A high fever requires immediate medical attention because it means the infection is getting worse. If the body temperature is too high, it can easily cause brain damage and dehydration, especially if the fever persists.

A low-grade fever is generally between 37.3 and 38 degrees (axillary). Many diseases 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. It is difficult to find out the cause of low-grade fever through routine tests such as blood, urine, and stool. Some low-grade fevers caused by bacterial infections can only be detected through bacterial culture.

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. It is recommended to go to the hospital for relevant examinations to avoid worsening of the cause of the fever.

Therefore, whether it is a high fever or a low fever, it is very serious. Do not take medicine on your own!!!
