The most critical management measure for diabetic patients who have been wasting is weight gain. This weight gain is more recommended for treatment with insulin because diet is often controlled. Because insulin is the only hormone that promotes synthesis, insulin treatment maximizes the conversion of glucose into fat and protein, which facilitates weight gain in diabetic patients. Because if the weight is significantly lean, the patient’s entire insulin sensitivity will be greatly increased, and the patient’s blood sugar will show the manifestation of brittle blood sugar. That is, the patient’s blood sugar will fluctuate very much, and there is a possibility of a roller coaster ride. In order to avoid such drastic fluctuations in blood sugar changes, it is necessary for very lean diabetic patients to gain weight appropriately. At the same time, it is important to note that oral hypoglycemic drugs like metformin and acarbose should not be taken, because they have the effect of lowering body weight, which is not good for the control of the condition of such patients.
