What is the cause of postprandial hypoglycemia

summary

Postprandial hypoglycemia is a problem that we are very concerned about. Many patients usually have elevated blood glucose after eating. We should be very clear about it. However, some patients have the opposite situation, especially female patients, who may have symptoms of postprandial hypoglycemia at some time. Long term hypoglycemia can lead to diabetic complications, sugar friends should be vigilant. So, how does hypoglycemia after diabetic meal return a responsibility?

What is the cause of postprandial hypoglycemia

First: how to understand postprandial blood glucose: experts explain that 2-hour postprandial blood glucose refers to timing from the first meal and measuring blood glucose after 2 hours. When measuring, take medicine, inject insulin and eat food at the same time and dose as usual. The 2-hour postprandial blood glucose is affected by the type of food, the speed of gastrointestinal peristalsis, the amount of exercise after meals and the level of blood glucose before meals.

Second: how much postprandial blood glucose is hypoglycemia? The normal value of blood glucose before meal is 3.9-6.1 mmol / L, and the normal value of blood glucose after meal is less than 11.1 mmol / L. However, due to the different constitution and condition of diabetic patients, the normal 2-hour postprandial blood glucose of diabetic patients should be at least less than 11.1 mmol / L, preferably less than 7.8 mmol / L. But if it is less than 5mmol / L, it is postprandial hypoglycemia.

Third: the causes of postprandial hypoglycemia in patients with urine: 1. Excessive insulin secretion and delayed peak. Under normal conditions, blood glucose will rise after eating. About 30-60 minutes, blood glucose will reach the peak and then decline. Plasma insulin level will also rise to the peak in 30-60 minutes, which is 5-10 times of the basic value, then decline, and return to the basic level in 3-4 hours. Therefore, although the blood sugar of normal people after meals is increased, it fluctuates in a certain range. Patients with type 2 diabetes mellitus may have excessive insulin secretion (hyperinsulinemia) and delayed peak. Insulin is maintained at a high concentration but can not return to the baseline level, resulting in lower postprandial blood glucose or even hypoglycemia. 2. Insufficient diet and excessive postprandial exercise are two important basic measures for the treatment of diabetes. Strict diet control and proper exercise are conducive to weight loss, improvement of hyperglycemia and reduction of hypoglycemic drugs. But the diet plan should be strict and long-term implementation, exercise should be regular. If the diet is insufficient or the intensity of postprandial exercise is too high, patients may also have low postprandial blood glucose, or even hypoglycemia. 3. If the dosage of hypoglycemic drugs is too large, it does not match the diet, or other drugs that enhance the hypoglycemic effect of hypoglycemic drugs are used at the same time, the postprandial blood glucose may also be significantly reduced.

matters needing attention

When the blood glucose 2 hours after a meal is lower than that before a meal, we can increase the number of monitoring, such as 1 hour and 3 hours after a meal, and record the data, so as to find the rule of blood glucose change. Then, consult the doctor, analyze together, find out the reasons, and adjust diet, exercise and medicine if necessary.
