High fever refers to hyperthermia. Recurrent high fever in a five-year-old child may be caused by respiratory system diseases, digestive system diseases, nervous system disorders, etc. Treatment should be based on the underlying cause.

1. Respiratory System Diseases

Recurrent high fever may result from exposure to cold or infection by other pathogens. Parents should take the child to the hospital for a comprehensive physical examination and relevant blood tests to identify the cause and enable targeted treatment. At the same time, appropriate antipyretic therapies should be used according to the child's body temperature.

2. Digestive System Diseases

If gastrointestinal inflammation is caused by bacteria, viruses, or other infectious agents, it may lead to recurrent fever accompanied by gastrointestinal symptoms such as nausea, vomiting, bloating, and diarrhea. Under medical guidance, medications such as domperidone granules, mosapride granules, or cisapride granules may be administered for treatment.

3. Nervous System Disorders

In cases of encephalitis or meningitis, recurrent fever may be accompanied by symptoms such as headache, nausea, and vomiting. Under medical guidance, medications such as isoniazid granules, rifampicin granules, or ethambutol granules may be used for treatment.
