A few of my fat friends and I had a good conversation and strongly expressed their desire to have sleeve stomach surgery. However, there are still concerns about the surgery, and they are more worried about the long-term results and long-term complications and side effects after the surgery, so I will answer them all together here. Is it safe to have surgery for diabetes? 1. Are there any risks associated with surgery? Weight loss and diabetes surgery is a mature surgical procedure. Gastric bypass is the most common and successful combined weight loss and diabetes surgery in the United States because of its obvious effect on weight loss and blood sugar control, while sleeve gastrectomy does not change the physiological state of the gastrointestinal tract and does not interfere with the normal digestion and absorption of food, and is a widely used weight loss procedure in Europe at present. The overall safety of bariatric and diabetic surgery has been greatly improved with advances in technology, surgical experience, and improved preoperative and postoperative care. The risks associated with a single bariatric and diabetic surgery are similar to (or even lower than) those associated with some of the more common surgeries around us, such as laparoscopic cholecystectomy. 2. How effective is bariatric and diabetic surgery in treating diabetes? A large-scale analysis of a 25-year prospective randomized controlled study abroad found that the percentage of excess weight loss after gastric bypass surgery was 65% to 70%, and the remission rate of type 2 diabetes was 80% to 85%, and could be maintained for a long time. In China, the remission rate has some variability due to the grasp of the surgical indications and the treatment before and after surgery, but the overall effect is still very satisfactory. 3.Will there be recurrence if the lifestyle is not improved after surgery? Even if you have weight loss surgery, it is not a permanent solution. If you do not pay attention to diet control and exercise after surgery, the effect of surgery will be compromised and you may even need to have surgery again. After the bariatric surgery, patients must follow the doctor’s instructions, change bad habits and actively exercise properly. Among them, the diet should be light, avoid greasy food or sweet food; to eat in small amounts, but not full (seven or eight minutes full is appropriate), and chew slowly; drink more water (6~8 cups per day), avoid carbonated drinks. 4.Postoperative micronutrient deficiency and supplementation? That is, there are mainly vitamin B1 and B12 deficiency, iron deficiency, folic acid deficiency, calcium deficiency, anemia, and protein deficiency. There will be unique hair loss after bypass surgery, and generally the hair will grow vigorously again after six months. We, at the Gastroenterology Department of Tsinghua Changgeng Hospital in Beijing, not only have professional case managers to follow up, but also have strong support from the professional Endocrinology and Metabolism Medicine and Nutrition Department for joint outpatient follow-up and regular initiative to contact patients for review, health guidance and nutrition regulation to ensure your health. The main effects of the surgery: 1.Reducing food intake and absorption, thus reducing energy intake and glucose metabolic load. 2.Reducing the patient’s weight and reducing insulin resistance caused by fat accumulation due to simple obesity. 3.Gastrointestinal tract reconstruction changes the secretion of hormones in the intestine-insulin axis, thus improving glucose metabolism. 4.The cure rate of type 2 diabetes after laparoscopic gastric diversion is 92%, the invalidity rate is 0%, and there are no surgical complications that cannot be recovered, and the surgical mortality rate is 0%. At present, it has been carried out maturely in China.
