Weight Loss Surgery Procedures

Weight Loss Surgery Procedures

Types of Bariatric Procedures

There are three types of widely performed, minimally invasive bariatric procedures, performed in most cases using laparoscopic tools inserted through small incisions in the abdomen.

Gastric bypass surgery creates a smaller stomach and allows food to pass around the first part of the small intestine. You will feel full more quickly than when your stomach was its original size, which reduces the amount of food you eat. Bypassing part of the intestine also results in fewer calories being absorbed. This leads to weight loss.

Sleeve Gastrectomy creates a thin sleeve of stomach by using a stapling device, and removal of the rest of the stomach.  The sleeve is about the size of a banana which limits the amount of food you can eat and helps you feel full sooner. This results in fewer calories being consumed due to a reduced amount of food you can eat.  


Adjustable gastric banding is a restrictive type of weight loss surgery. It involves placing an inflatable silicone band around the upper stomach to restrict food intake. The band can be tightened or loosened over time to change the size of the passage.
