Three hours after meal blood glucose is higher than two hours need to clarify the reason, if the blood glucose value is not very high, usually not dangerous, three hours after meal blood glucose is higher than two hours may be caused by unreasonable dietary structure, indigestion and other reasons. 1. Unreasonable dietary structure: the proportion of protein and fat in the diet is high, the digestion and absorption of protein and fat is slow, and the blood glucose concentration peaks only three or four hours after the meal, which may result in a higher blood glucose level in three hours after the meal than in two hours, which can be achieved by adjusting the diet. 2. Indigestion: Slower gastrointestinal peristalsis leads to indigestion, which results in slower digestion and absorption of food, causing the 3-hour postprandial blood glucose to be higher than the 2-hour blood glucose. This situation is not serious, you can follow the doctor’s instructions to take domperidone, mosapride and other drugs to promote gastrointestinal dynamics treatment. The cause and treatment of three-hour postprandial blood glucose higher than two-hour postprandial blood glucose can be clarified under the guidance of the doctor.
