Insulin dosage, the basal amount of insulin secreted in normal human body is about 24 units, and the amount secreted after three meals is about 6 or 8 units, that is, the total amount of insulin needed in human body is about 48 units after the pancreas is completely removed. For diabetic patients, insulin is needed in case of high blood glucose due to hypoglycemia or insulin resistance, and the amount of insulin is usually calculated based on the patient’s weight and the patient’s blood glucose level at this time. Generally, the basal insulin dosage is calculated at 0.2 units per 1 kg of body weight or based on the patient’s fasting blood glucose value to determine the basal insulin. The insulin dosage after three meals is generally calculated according to 0.2 units per 1kg body weight, and then distributed equally before three meals or distributed according to 2 units more for breakfast than for dinner.
