Patient's question:
Is the persistent low fever in children due to anemia?This child has been in this condition for some time, and as parents, we are very concerned. We hope the doctor can give us some advice.
Doctor's answer:
Many diseases can cause prolonged low fever in children. Broadly speaking, they can be attributed to either organic diseases or functional disorders. Among the organic causes of prolonged low fever in children, chronic infections are the most common. Prolonged low fever refers to a sustained body temperature between 37°C and 37.4°C for more than two weeks. The causes of prolonged functional low fever in children may be related to dysfunction of the body's thermoregulatory center or autonomic nervous system dysfunction. The characteristics of this type of low fever include higher body temperature in the morning and afternoon compared to the evening and night, often accompanied by symptoms such as excessive sweating, fatigue, poor appetite, and irritability. However, physical examinations show no abnormal signs, and laboratory tests also yield no abnormal findings. It is recommended to treat the condition based on the results of the examinations.
