There is no such thing as “how to restore hypoglycemia to normal quickly”, the awake patients in hypoglycemic attack need to eat sugary food immediately, and the hypoglycemic comatose patients need to be injected with glucose intravenously. During an acute attack of hypoglycemia, awake patients can eat candy, sugar water, chocolate, cookies, sugary drinks and other sugary foods, which can quickly relieve the patient’s symptoms of hypoglycemia; comatose patients can not be fed orally and need intravenous glucose infusion for treatment. In addition, patients with hypoglycemia should pay attention to avoiding triggers and treating the causes of hypoglycemia. Triggers include insufficient food, increased consumption, etc., in which case the amount of food should be increased at the same time as the amount of consumption is increased; and the causes of hypoglycemia include pre-diabetes, insulinoma and other special factors, which need to go to the endocrine department of hospitals for further investigation of hypoglycemia causes. If symptoms of hypoglycemia are not relieved after supplementation of sugary foods or if hypoglycemia occurs frequently, it is recommended to go to the endocrinology department of the hospital for consultation.
