Why does my child keep having fever?

Children are very prone to fever. This is because their immunity is relatively poor, and they may have a fever when their bodies are slightly stimulated, such as after catching a cold or being heated. When a child has a fever, you must drink plenty of water, try to feed the child liquid food, etc. If the child at home has a repeated fever, you should consider the following reasons.

Why does my child keep having fever?

Why do babies have repeated fevers? Experts point out that the main reasons for babies' fevers are:

1. Non-infectious fever

It is not caused by various infectious diseases. It is caused by sterile substances or various inflammations acting on the body temperature regulation center, dysfunction of the body temperature center, or excessive heat production and reduced heat dissipation due to various reasons, resulting in a temperature rise exceeding the normal range.

2. Fever of unknown cause

The broad concept of fever of unknown origin refers to all people with fever of unknown origin. However, the narrow concept of fever is still used clinically, that is, fever of unknown cause. Fever persists for more than 3 weeks, with body temperature above 38.5℃, and a clear diagnosis cannot be made after detailed medical history, physical examination and routine laboratory tests.

3. Central fever

Central fever can also cause the baby to have repeated fevers. Central fever refers to fever caused by abnormalities in the body temperature regulation center due to lesions in the central nervous system. Before diagnosing it, fever caused by systemic or local inflammation and other causes of fever should be strictly excluded. Intracranial diseases accompanied by fever are mostly critical cases, and the fever in most patients is caused by intracranial inflammation, lung infection, and urinary tract infection. For those with unexplained moderate fever whose source or cause of infection cannot be found at the moment, it should not be easily assumed to be central fever. Systemic or local infection causes should be repeatedly sought to exclude them, and attention should be paid to drug fever and other causes of fever.

Experts point out that the nervous system of infants and young children is not yet fully developed, and they are prone to high fever or having their body temperature rise quickly after taking medicine to reduce the fever. What parents can do is to provide adequate nutrition according to the child's age and physical development, and add complementary foods in a timely, reasonable and balanced manner. If mothers want to effectively help their babies prevent diseases, the more effective way is to increase their own resistance, insist on taking their children out more often or urging them to participate in outdoor activities, and strengthen physical exercise to enhance their ability to adapt to cold climates.
