This procedure involves the removal of approximately 80% of the stomach. The surgery achieves weight loss through both restriction, by creating a smaller stomach, and complex metabolic changes in the gastrointestinal hormones. As a result, patients experience reduced hunger and earlier feelings of fullness when consuming food.
On average, individuals undergoing sleeve gastrectomy can expect to lose around 65 to 70% of their excess weight within a period of twelve to eighteen months.
Sleeve gastrectomies are typically performed using laparoscopic techniques and require a hospital stay of two to three days. Most patients can resume work within two to four weeks following the procedure.
