The main methods of controlling 2-hour postprandial blood glucose include lifestyle interventions and medication. Lifestyle interventions include nutritional therapy and exercise therapy, and both the quality and quantity of diet can affect postprandial blood glucose. A diet with a high glycemic index can lead to an increase in postprandial blood glucose levels. Therefore, among diabetic patients, it is recommended to consume a diet with a low glycemic index and to reduce the intake of refined and processed foods, which can effectively reduce postprandial blood glucose. In addition to dietary control, proper exercise can help burn body heat and increase insulin sensitivity. It is recommended to start exercising half an hour after meals, which can be jogging, brisk walking or strolling for about half an hour. Medication includes oral hypoglycemic drugs and injectable preparations, oral drugs such as acarbose, reglaneride, glimepiride, etc., and injectable preparations including insulin and insulin analogs. Therefore, patients need to pay attention to diet, consume foods with low glycemic index, exercise moderately half an hour after meals, and take oral hypoglycemic drugs and insulin injections under the guidance of a doctor to control blood glucose two hours after meals if necessary.
