Recently, my child has had high fever. They have taken medicine and been given intravenous fluids, but the fever comes back occasionally, accompanied by occasional dry vomiting. My child has a continuous runny nose. When taken to the hospital for a thorough examination and tests, everything was said to be fine. I would like to ask what is going on.Doctor's answer:
Based on your situation, long-term fever guidance is recommended: There are many diseases that can cause prolonged low fever in children, which can be summarized into two major categories: organic diseases and functional endocrine disorders. Among the low fevers caused by organic diseases, chronic infections are the most common, such as pediatric tuberculosis, chronic pyelonephritis, chronic sinusitis, and certain parasitic diseases. For low fevers caused by infectious factors, treatment should target the pathogen of the infection with appropriate measures. At the same time, many non-infectious factors can also lead to prolonged low fever, such as pediatric anemia, malignant tumors, hyperthyroidism, systemic lupus erythematosus, and others. For these non-infectious causes of low fever, detailed and thorough examinations should be conducted to confirm the diagnosis and actively treat the underlying disease causing the fever. If hospital examinations show that all tests are normal, it may be considered functional low fever. Functional low fever refers to a child's body temperature ranging between 37.4°C and 38°C and persisting for more than two weeks.
