Weight loss after sleeve gastrectomy is usually significant. Sleeve gastrectomy usually refers to laparoscopic sleeve gastrectomy, which involves laparoscopically removing most of the stomach, including the fundus, and the body of the stomach, leaving only a small portion of the stomach, which has a volume of about 100 ml. Sleeve gastrectomy is a common form of bariatric surgery today. After the sleeve gastrectomy, the patient’s diet will be greatly reduced due to the reduction in stomach volume. After eating a small amount of food, the patient may feel full and stop eating to achieve the goal of weight loss. Sleeve gastrectomy is now clinically significant in weight loss, and patients can achieve good weight loss by reducing food intake. If sleeve gastrectomy is needed, it is recommended to go to the hospital in time to consult a specialist if the surgery is suitable for you and follow the doctor’s instructions.
