After a child has hypoglycemia, it is best to eat the following foods or medicines: first, give the child chocolate. Hypoglycemia can cause pallor, cold sweat, dizziness, and in severe cases, fainting. When hypoglycemia occurs, it is necessary to apply chocolate to children in time, because the sugar content in chocolate is very high, which can quickly correct the hypoglycemic state of children. Secondly, children can be given medication, such as applying glucose oral solution to children for treatment. After giving glucose to children, the hypoglycemia in the body will be corrected quickly, and other complications caused by hypoglycemia such as brain damage can be avoided.
