Gastric Sleeve Surgery in Tucson

Gastric sleeve surgery (vertical sleeve gastrectomy, or VSG) is a laparoscopic procedure that removes approximately 80% of the stomach. The remaining stomach is shaped into a narrow tube, about the size of a banana. This reduces the hunger hormone ghrelin and limits food intake, resulting in significant, durable weight loss.

Most patients lose 60-70% of their excess body weight within 12-18 months after surgery. For example, if you have 100 pounds of excess weight, you can expect to lose 60-70 pounds. Results depend on your starting weight, adherence to the nutritional program, and lifestyle changes. Use our free weight loss calculator for a personalized estimate.

Most patients return to work within 1-2 weeks. You'll be up and walking the same day as surgery. Because the procedure is laparoscopic (small incisions), recovery is faster and less painful than open surgery. Full recovery takes about 4-6 weeks.

The gastric sleeve removes part of the stomach but doesn't change the intestinal pathway. Gastric bypass creates a small stomach pouch and reroutes the intestine. The sleeve is a simpler procedure with fewer nutritional deficiency risks, while bypass may be better for patients with diabetes or severe acid reflux.
