Types of Weight Loss Surgery

WMC surgeries

Gastric Bypass

Roux-en-Y gastric bypass surgery is considered by the American Society for Metabolic and Bariatric Surgery (ASMBS) and the National Institutes for Health as leading surgical tool for significant lasting weight loss. It works by making the stomach smaller, allowing for smaller meals. It also causes food to bypass part of the stomach and small intestine, causing less absorption of calories and important changes in hormones that help to promote fullness.

Gastric Sleeve

Also called gastric sleeve, this procedure removes approximately 80% of the stomach, leaving a small tubular pouch. People are full with much smaller meals. It also changes the hormones in the stomach, helping to reduce hunger.

Duodenal Switch

Duodenal Switch is an operation reserved for the severely obese patients. It is a combination of sleeve gastrectomy and an intestinal bypass. It produces more weight loss than a sleeve gastrectomy or a gastric bypass.

Nutritional Counseling

Weight loss is more than a procedure - it's a lifestyle change.
