What is the appropriate blood sugar control level for diabetes? Is it better to use insulin or oral medication to lower blood sugar?

Glucose control goals for patients with diabetes generally advocate fasting glucose control of 4-6 mmol/L. 2-hour postprandial glucose control of 10 mmol/L or less is generally advocated. Glycosylated hemoglobin is controlled at 6.5%.

The choice of oral medication or insulin injection therapy for diabetic patients needs to be decided on a case-by-case basis. If the degree of blood glucose elevation is not too high, below 10 mmol/L, and the blood glucose fails to reach the standard by means of 4-6 weeks of diet control and physical exercise, oral hypoglycemic medication adjustment is recommended, and long-acting medications are chosen as much as possible to improve patient compliance and efficacy. The commonly used drugs are metformin hydrochloride extended-release tablets, glibenclamide tablets, elimination pills, glipizide dispersible tablets, etc.

If a high degree of elevated blood glucose is found, insulin therapy or a combination intervention of insulin therapy plus oral medication is generally recommended. Insulin is divided into short-acting insulin, intermediate-acting insulin, and long-acting insulin according to the duration of action maintenance. Short-acting insulin is usually injected before three meals according to the specific value of postprandial blood sugar, and medium-acting insulin is generally recommended to be injected twice a day. Long-acting insulin is generally injected once a day according to basal and fasting blood glucose.
