Treatment of hyperglycemia: Firstly, dietary treatment, reasonable rationing of meals and dietary control, combined with appropriate amount of exercise, is the basic measure to reduce hyperglycemia. Secondly, on this basis, appropriate hypoglycemic drugs are used to control blood sugar. In case of milder diabetes, oral hypoglycemic drugs, such as metformin and pioglitazone, can be applied. Sulfonylureas, such as glimepiride, can be added in cases of poor glycemic control. When the patient’s diabetes has a long duration, fasting hypoglycemic drugs blood sugar can not be controlled, you can consider applying insulin therapy.
