Weight loss surgery is not cosmetic surgery or liposuction, it is minimally invasive surgery! Sleeve gastrectomy has been introduced to our country for more than ten years, but do you know what it really is? Do you know what the indications are? Here’s what you need to know! Sleeve gastrectomy (laparoscopicsleevegastrectomy, LSG) is now the most important procedure for the treatment of obesity and type 2 diabetes. Surgical method: Generally, laparoscopic minimally invasive techniques are applied to remove the greater curvature side of the stomach, leaving only a narrow part of the lesser curvature side like a sleeve, so it is called sleeve gastrectomy. The principle of this surgery for the treatment of obesity and diabetes is as follows: 1) the volume of the stomach is reduced, and now the volume is about 150 ml. 2) the fundus of the stomach is resected, which reduces the level of Ghrelin hormone, the hunger hormone secreted by it. This makes the patient feel full easily and reduces eating, thus reducing calorie and sugar intake.2 Increased levels of the insulin secretion hormone GLP-1 and the appetite suppressant peptide PYY3-36 secreted by the gut after the operation promotes insulin secretion and increases the sensitivity of cells to insulin. This procedure can reduce over 70% of overweight body weight in the first year after surgery, (about 60 pounds or more at 200 pounds), with a diabetes remission rate of 75% or more. It is the most popular among the three procedures, adjustable gastric banding for weight loss (LAGB) and diversion (By-pass), because it is in the middle of the list in terms of therapeutic effect and postoperative complications. Its indications:1 Obese patients with BMI greater than 35, or BMI greater than 28 but with type 2 diabetes, diabetic patients must have some residual function of the pancreas, and c-peptide must be higher than half of the lowest value of the normal range of values.2 Obese patients with poor non-surgical results and easy to rebound. Cut stomach weight loss surgery is a kind of weight loss surgery in order to let the patient to reduce dietary intake, as the name suggests is to remove a part of the patient’s stomach, so that can make the amount of food reduced, so as to obtain the effect of weight loss, what are the sequelae of cut stomach weight loss surgery? What are the after-effects of gastrectomy surgery? Two major after-effects need to be vigilant 1. After gastrectomy surgery, the stomach becomes much smaller, so as the stomach can not hold more food, so the amount of food will be reduced, but it should be noted that, after gastrectomy surgery, the patient is more prone to nausea and vomiting once the patient is ingesting too much food. The increase in the number of cells in the lining of the stomach and the increase in the size of the cells in the lining of the stomach will make our stomach larger. When the development of our organs is complete, the total number of cells in the lining of the entire stomach is fixed and will not increase in the future. Cutting off 2/3 of the stomach now will leave 1/3 of the cells in the lining of the stomach. At the same time, there is a limit to how large each stomach lining cell can become. Therefore, the stomach may still increase in size after the surgery, but the enlargement is limited. Moreover, once a person who has undergone gastrectomy eats a little too much, it will immediately cause nausea and vomiting. 2. Eat less intake of nutrients also become less, so the body absorbs less nutrients, so many people may be malnourished, especially for the children who are growing and developing, if you must do gastrectomy, you must timely not from a variety of nutrients, such as the need to supplement some of the vitamins, trace elements, such as eat some 21 gold vita, good survival tablets, etc. The child should be able to take a few vitamins and micronutrients.
