The hungrier the stomach, the higher the blood sugar, may be related to the treatment irregularities, post hypoglycemic stress reaction, etc., should be directed to the cause of the conditioning, standardized drug therapy and dietary intervention. 1. Unstandardized treatment: Diabetic patients should use hypoglycemic drugs as prescribed by the doctor, so that the blood sugar gradually reaches the appropriate level. If the patient’s blood glucose control is poor and dietary control is not strict, the glucose in the body can not be transferred to the cells for energy metabolism, and the patient will have an obvious feeling of hunger. While the blood sugar remains high and fails to be controlled. It is recommended that patients should standardize drug therapy under the guidance of doctors, and commonly used drugs include acarbose, metformin, dagliflozin, various short-acting, long-acting or premixed insulin. Drug treatment should be accompanied by dietary control and moderate exercise. 2. Post-hypoglycemic stress reaction: If patients over-control their diet or use hypoglycemic drugs improperly, symptoms of hypoglycemia can occur, and then patients will have obvious hunger. When hypoglycemia occurs, the human body produces a large amount of glucagon, and blood sugar will rise. It is recommended that patients follow the doctor’s instructions to standardize the use of hypoglycemic drugs, reasonable control of the diet every day, not excessive control. Glucose can be given orally or intravenously when hypoglycemia occurs. If the patient has obvious hunger and high blood glucose, he/she should go to the endocrinology department of the hospital to actively find out the cause and adjust the treatment plan.
