After eating oatmeal, if there is something wrong with blood sugar, it will detect an increase in blood sugar. However, if the blood sugar level is normal, even eating oatmeal will not detect the increase of blood sugar. However, any food in nature has the function of increasing sugar, and there is no hypoglycemic food or sugar-free food.

Therefore, after eating oatmeal, the blood sugar level will rise, but normal people will have enough insulin secretion to keep blood sugar within the normal range. If they are patients with impaired glucose regulation, it is easy to see that after eating oatmeal, their blood sugar cannot be controlled within the normal range through the hypoglycemic effect of insulin.
