Weight loss surgery, also known as bariatric surgery, is a surgical procedure that helps people lose weight by altering the digestive system.
There are three main types of weight loss surgery: gastric bypass, sleeve gastrectomy, and adjustable gastric banding.
Gastric bypass surgery involves creating a small stomach pouch and rerouting the small intestine to this pouch, which limits the amount of food that can be eaten and absorbed.
Sleeve gastrectomy involves removing a large portion of the stomach, leaving a smaller sleeve-shaped stomach that limits the amount of food that can be eaten.
Adjustable gastric banding involves placing a band around the upper part of the stomach, creating a small pouch that limits the amount of food that can be eaten.
Weight loss surgery is typically recommended for people with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health problems.
