Bariatric surgery can help you lose your excess body weight and lower your risk of obesity-related health conditions. Surgery contributes to weight loss in two main ways: restriction and malabsorption.

Restriction 

By physically limiting the amount of food your stomach can hold the patient feels fuller after eating much smaller portions of food.

Main restrictive procedures:

Gastric Balloon

Gastric Band (adjustable)

Gastric Sleeve

Malabsorption

By shortening or bypassing part of the small intestine, your body absorbs fewer calories and nutrients. 

Main malabsorptive procedures:

Roux-en-Y Gastric Bypass (mineral malabsorptive, not calorie malabsorptive)

Biliopancreatic Diversion with Duodenal Switch (BPD-DS) 

Mini Gastric Bypass (MGB)

Most weight loss surgeries today are performed via laparoscopic surgery which is a minimally invasive technique. 

Please seek and follow the specific guidelines from your bariatric team. Guidelines vary for individual patient needs and surgeries.
