Excessive insulin secretion: Hypoglycemia caused by excessive use of exogenous insulin can be adjusted under doctor’s guidance; hypoglycemia caused by insulinoma can be treated by surgery. 2. Improper use of hypoglycemic drugs: common hypoglycemic drugs, such as glibenclamide, glipizide and other sulfonylureas, can cause hypoglycemic reaction if used improperly, and the medication can be adjusted after communicating with the doctor. 3. Treatment of hypoglycemia: once the symptoms of hypoglycemia appear, sugar water or sugary food should be given in time. If the symptoms do not get better or worsen significantly, and there is a consciousness disorder, coma, etc., it is recommended to consult a doctor in time, to clarify the cause of the disease, and to follow the doctor’s instructions for standardized treatment.
