In case of hypoglycemia, the first and fastest supplement is glucose, which does not need to be digested in the body and is directly absorbed into the bloodstream, and can quickly relieve the symptoms of hypoglycemia. 1. If the patient has recurrent hypoglycemia, it is recommended to go to the hospital or drugstore to buy glucose powder, or you can drink some white sugar water, which can raise the blood sugar faster, and then you can drink some sugary drinks, and some of them contain some glucose and sucrose, which can be absorbed very quickly. 2. Secondly, you can eat some high-sugar foods, including chocolate, candy, milk sugar, honey, cookies and so on. If you suffer from functional hypoglycemia, you need to reduce carbohydrate intake appropriately, and eat more high-protein foods, such as meat and eggs. Repeated occurrence of unexplained hypoglycemia needs to be clearly diagnosed and treated under the guidance of a doctor.
