Delayed insulin secretion generally means that a delay has occurred in the current peak of insulin secretion by insulin cells, but the amount of insulin has not decreased. It usually suggests that type 2 diabetes may be present, and usually cannot be easily and fully recovered. Delayed peak insulin secretion is an important cause of diabetes, and some people with type 2 diabetes may have delayed peak insulin secretion. Peak insulin secretion in the general population is 30-60 minutes after a meal, whereas in type 2 diabetes it may be 2-3 hours after a meal. The delay in peak insulin secretion can seriously affect the metabolism of blood sugar in the body, thus causing type 2 diabetes. The delay can be improved and relieved by diet control, moderate exercise and medication under the guidance of a doctor, and full recovery is usually not achieved. Commonly used drugs include short-acting insulinotropic agents such as Repaglinide. If delayed insulin secretion is detected, it is recommended to go to the hospital in time, under the guidance of the doctor for treatment, and regularly monitor blood glucose as well as insulin.
