1. Will the surgical rerouting of the stomach and intestines affect the absorption of nutrients? (1) Protein absorption is limited to the lower and middle jejunum and ileum. According to the follow-up data of GBP at home and abroad, there is no report of serious complication of protein deficiency. (2) Carbohydrates are not mixed with the relevant digestive enzymes in time, reducing the degradation rate of food starch. Postoperative blood glucose can thus avoid excessive peaks, and pancreatic islet function can be restored. (3) Lipidic foods promote the entry of bile and pancreatic juices into the intestines by stimulating the release of cholecystokinin, which degrades the lipids in the food, and GBP delays the formation of lipid coeliacs, resulting in the rapid passage of lipids into the large intestine and their elimination. (4) may reduce the vitamin and iron, calcium absorption, although not serious, the postoperative period should still pay attention to supplement a variety of multivitamins and minerals. 2. Endocrinologists generally believe that diabetes is not yet curable, what do you think about this? Experts in the endocrine community generally believe that diabetes is lifelong and incurable, what is the reason? They believe that insulin resistance is a natural phenomenon, which is prevalent in nature and cannot be eliminated; the function of pancreatic islets decays. After this surgery, insulin resistance subsides or even disappears; pancreatic islets proliferate. So that both of their perceived causes no longer exist. And after a long period of postoperative visits, the patient’s recovery is really good! 3. Will the cured diabetes come back? The patient’s condition will get better and better because the pancreatic islets proliferate, the pancreatic islet function is restored; the insulin resistance phenomenon is also eliminated.
