Blood glucose 2 hours after a meal is not necessarily higher than blood glucose 1 hour after a meal. If there is an increase in blood glucose 2 hours after a meal, it may be due to a delay in insulin secretion, and it may also be related to the type of meal eaten. If you eat food that is high in fat and protein, and digestion and absorption are relatively delayed, the 2-hour postprandial blood glucose will be higher than the 1-hour blood glucose. In normal people, 1-hour blood glucose is higher than 2-hour blood glucose after meal, this is due to the elevation of blood glucose after eating will stimulate the pancreas to secrete insulin, insulin secretion into the blood, can quickly reduce blood glucose, blood glucose peaks in 0.5-1 hours. However, in diabetic patients, due to the delay in insulin secretion, the blood glucose remains high 2 hours or even 3 hours after the meal. If you find abnormal postprandial blood glucose, you should go to the hospital in time to get a clear diagnosis and active treatment under the doctor’s guidance.
