Diet after sleeve gastrectomy The diet routine for gastric sleeve patients begins before surgery. Where some centers and clinics prefer to start two months before the surgery, but most doctors encourage patients to follow a diet at least two weeks before the sleeve gastrectomy.
Whatever the duration of the diet, the main goal is to reduce the fat accumulated around the liver as much as possible. The liver, which is located near the stomach, may affect the course of the sleeve gastrectomy operation in the event that there is accumulated fat that increases its size, which makes the risks of the operation higher and its duration longer. In addition, following a diet before sleeve gastrectomy helps the body to adapt more to surgical changes, speed up the recovery process, and make the patient get used to the post-operative diet easily.
The diet before laparoscopic sleeve gastrectomy includes many restrictions and instructions. The main foods to avoid during this period are carbohydrates, fats and sweets. The patient needs to eat proteins, vegetables, and low-calorie fluids. As the date of the operation approaches, the diet will include more fluids. It goes without saying that smoking, drinking alcohol and drinks with a high caffeine content are prohibited.
Some medications must also be stopped before surgery, in coordination with the specialist doctor.
