Laparoscopic sleeve gastrectomy, also known as gastric sleeve surgery, is a weight loss procedure in which the stomach is re-sectioned to remove approximately 70 to 80 percent of its capacity. The remaining stomach is formed into a tube, like a sleeve. Although the stomach is reshaped, no small intestine re-route performed. This procedure is a good option for people with clinically severe obesity (body mass index 35 and above), who have been unable to bring down their weight by other means.
Frequently Asked Questions
How gastric sleeve surgery work?
After the procedure, the new formed stomach has limited capacity. This prevents a patient from overeating, as there is no room for a large intake. The patient feels full faster, and smaller portions of food lead to weight loss. The second mechanism is a physiologically diminished appetite. Removing most of the stomach produces chemical changes in the body that decrease appetite. Appetite hormones, such a ghrelin and leptin, control appetite and energy balance and have a profound link to obesity. By removing the portion of the stomach that produces these hormones, the sleeve gastrectomy alters the hormonal balance and dramatically diminishes appetite.
What will I experience before and after gastric sleeve surgery?
You may be required to follow a special pre-operative diet in the week leading up to surgery. You will be instructed to avoid eating or drinking the night before your surgery. Sleeve gastrectomy is an inpatient procedure performed under general anesthesia. Once you awaken, you will be taken to a recovery room and monitored in the hospital for approximately 2 to 3 days before being released to go home. You will continue to recover for several weeks and may return to work within 2 weeks and a month after the procedure.
