The treatment of hypoglycemia in 6-year-old children mainly includes symptomatic treatment as well as causative treatment. 1. Symptomatic treatment. For mild or moderate hypoglycemia, you can take sugar water by mouth, eat candies, cookies, etc. If the hypoglycemia is caused by drugs, stop using the drugs immediately; for severe or even coma, you need to give glucose injection under the guidance of doctor. 2. Treat the cause. Preventing hypoglycemia is very important for the normal development of the central nervous system. If the child is suffering from congenital hyperinsulinemia, and if the hypoglycemia can’t be controlled by medication, we should consider choosing the surgical subtotal resection of the pancreas under the guidance of the doctor. When hypoglycemia occurs in a 6-year-old child, the cause should be identified in a timely manner in order to prevent untimely diagnosis that may affect the child’s growth and development.
