Postprandial hypoglycemia
Introduction
Introduction Postprandial hypoglycemia, also known as late postprandial dumping syndrome. It refers to the gastric emptying speed after gastric resection, glucose is quickly absorbed by the intestinal mucosa, causing a sudden increase in blood sugar, stimulating a series of hypoglycemia caused by excessive islet secretion of insulin.
Cause
Cause
Dumping syndrome refers to the loss of the pylorus or its normal function after gastrectomy and gastrojejunostomy due to surgery. The food in the stomach suddenly falls to the duodenum or jejunum, which can cause a series of symptoms. After gastric resection or gastrointestinal anastomosis, patients should eat less meals, eat more dry food, less soup, limit carbohydrates, especially sugar, should eat high protein, high fat and low carbohydrate diet, need to lie after eating About half an hour. Develop the habit of drinking water during meals or on an empty stomach. Take anticholinergic drugs (such as atropine, belladonna or prufenone) 20 to 30 minutes before meals to prevent excessive gastrointestinal motility. Oral administration of metobutamide (D860) 0.5 to 1.0 g can shorten the duration of hyperglycemia.Examine

Often eaten for 90-180 minutes (especially eating a lot of carbohydrates), after the onset, the performance is extremely weak, weak, dizziness, palpitation, trembling, cold sweat, severe cases can occur disturbance of consciousness. There were no obvious positive signs in the examination. Before the onset, plasma insulin is often 3-4 times higher than that of normal people, and blood sugar is significantly reduced at the time of onset. In a few cases, there may be a dumping syndrome, followed by postprandial hypoglycemia. Therefore, the detection of blood sugar is the main method of examination of this disease.
