How to avoid the harm of weight loss surgery?

The doctor replied:


gastrointestinal surgery was originally designed to reduce food intake, but in some cases, the effect of gastrointestinal weight loss surgery is "too good", so that patients can't eat at all. As soon as you eat, you have nausea and vomiting. In this case, you need to be hospitalized again., Even this can not completely avoid the occurrence of obesity. After the weight loss surgery, the patient's food intake and dietary preference will change, and the energy intake is much less than that before the surgery. However, whether one will regain weight is determined by the balance between energy intake and consumption. If one does not like to move and has a low basic metabolic rate, he will still face the problem of gaining weight by eating less and eating more meals
