If you suspect diabetes, you should go to the hospital and hang up the Department of Endocrinology. Because diabetes is an endocrine metabolic disease, you should hang up the Department of Endocrinology. Diabetes is an endocrine metabolic disease caused by insufficient insulin secretion or insulin resistance, which will cause the blood sugar to rise. After the blood sugar enters the human body, the blood sugar will remain high because there is no insulin for good conversion. If diabetes is suspected, it is recommended to check fasting blood glucose and blood glucose two hours after meal, and also check glycosylated hemoglobin to determine whether there is diabetes. If diabetes is confirmed, diet and exercise should be controlled. If the diet control can not make the blood sugar reach the standard, drug treatment should also be used.
