Is WEIGHT LOSS SURGERY right for you?

to Schedule Your Consultation


Bariatric surgery, or weight loss surgery, is an option for bariatric patients who were unsuccessful in losing weight through diet and exercise or those who have serious health problems due to their weight. 
At Summit Bariatric and Robotic Surgical Specialists, we offer several surgical procedures for weight loss: gastric sleeve, gastric bypass, and single anastomosis duodenal switch. 

Gastric Sleeve Surgery is a bariatric procedure that removes a portion of your stomach. Patients typically experience a reduction in appetite due to the reduced volume of the stomach and the decreased production of grhelin (the hunger hormone). After gastric sleeve surgery, you can expect to lose 25% to 30 % of your body weight in the first one to two years.

Gastric Bypass Surgery modifies your stomach and small intestine to bypass part of your digestive system. The size of your stomach and the length of your small intestine are reduced, causing you to consume and absorb fewer calories. In the first year or two after gastric bypass surgery, patients lose an average of  70% of excess weight. 

Single Anastomosis Duodenal Switch Surgery is in some ways similar to gastric bypass surgery in that it involves the stomach and small intestine. The duodenal switch is a two-part surgery, beginning with a gastric sleeve and then bypassing a majority of the small intestine. On average, patients can expect to lose 80% of excess weight over a two-year period.


Revisional Weight Loss Surgery is a procedure that corrects or improves prior weight loss surgery that has deteriorated over time or is no longer effective. Revision surgery is an option for patients whose previous weight loss procedure resulted in less-than optimal weight loss, weight regain, or post-surgical medical complications.
