Under normal circumstances, there is no significant increase in blood glucose two hours after eating noodles. Noodles have a high glycemic index, and patients with abnormal insulin secretion may have higher than normal blood glucose two hours after eating noodles. In general, blood glucose rises half an hour after a meal in normal people, peaks in about an hour, begins to fall in two hours, and approaches fasting blood glucose in three to four hours. So two hours after eating noodles blood sugar is generally not significantly higher. The glycemic index of noodles is high, if the blood sugar is still rising two hours after eating noodles, it means that there may be a delay in insulin secretion and other conditions, resulting in a delay in the peak of insulin, which can be seen in pre-diabetes, diabetes and other conditions. It is recommended to go to the hospital and ask the doctor to make a judgment when abnormal blood sugar occurs.
