For people who are obese to a certain degree (body mass index BMI ≥ 40), liposuction is only a slack job, which does not help much; and traditional methods of weight loss, such as dieting and exercise, are outnumbered and difficult to adhere to. Maybe only weight loss surgery (bariatric surgery) can help them, that is, to make the intestines or stomach thin, reduce the food intake or absorbed nutrients, and ultimately achieve weight loss.
Bariatric surgery can be divided into two types: one is a malabsorption type, which achieves the purpose of weight loss through a malabsorption effect similar to short bowel disease; the other is a restricted operation (stomach volume reduction surgery), which artificially uses Reduced stomach capacity makes the subject more susceptible to satiety and reduced appetite.
1. Slow weight loss (30% -40% in the first year, 50% -60% in the third year, and 50% -60% in the fifth year). The effect of long-term weight loss is not clear.
Method: After laparoscopically putting a flat ball made of silicone into the stomach, inject 500-600 ml of saline into the ball to make the stomach volume smaller, thereby reducing appetite.
Suitable for people: Suitable for those who need short-term weight loss, or as a transitional stage before long-term weight loss surgery, also suitable for those who are not suitable for surgery and do not have chronic stomach disease, and are not suitable for those who eat small meals and frequent snacks.
Possible complications: nausea, vomiting, bloating, diarrhea and other conditions may occur in the early stage, and reflux esophagitis, gastric ulcer, and poor gastric emptying may occur in the long term.
Not everyone can do gastric volume reduction and intestinal volume reduction surgery, otherwise complications may occur and even death may result. Experts believe that those who can perform bariatric surgery must have the following indications:
2. BMI ≥ 40, or BMI 28-40 and combined with diabetes, hypertension, hyperlipidemia, arthritis, sleep apnea syndrome, etc .;
