Gastric surgery sounds like a way to reduce weight that many friends would not choose, preferring to diet and exercise on their own, because surgery is something that sounds scary, but gastrectomy can help most obese patients and some obese patients with other complications to solve the problem of obesity and other diseases. There are many fat people who are very concerned about how gastrectomy helps people to reduce their weight. The surgical method and principle is not difficult to understand, the general surgery will apply laparoscopic minimally invasive technology to remove the large curved side of the stomach, leaving only the small curved side like a narrow part of the sleeve, so called sleeve gastrectomy. After the surgery, the volume of the stomach is reduced to about 150 ml. The removal of the stomach reduces the level of Ghrelin hormone, which is the main hunger hormone secreted by the stomach, and the patient can easily feel full and eat less, thus reducing the intake of calories and sugar, and the weight will naturally be lost. So how does surgery help patients relieve and treat type 2 diabetes? Because the increased levels of the insulin-producing hormone GLP-1 and the appetite-suppressing peptide PYY3-36 secreted by the intestine after surgery promote insulin secretion and increase cellular sensitivity to insulin, which is why many post-operative patients are able to maintain stable blood sugar by ditching medication. The results of surgery are also much more outstanding than other traditional weight loss methods. Not only does it not rebound, but the weight loss effect of surgery is outstanding, with over 60% to 70% of overweight weight loss in the first year after surgery and a diabetes remission rate of 68% to 75% or more. Of course, this is not simply surgery can be done, the regular medical institutions after this type of surgery will be equipped with professional health managers and nutritionists, to ensure that your late diet is reasonable and healthy, with the management of health managers can also achieve the best weight loss effect and maintain a longer period of time. If you still have doubts about the surgery, you can also learn more about it, perhaps this is the starting point of your weight loss success.
