Method 1

The most common type is called Roux-en-Y gastric bypass. With this method, the doctor staples or bands a part of your stomach, making it smaller and restricting how much food you can eat. The doctor also creates a passage so food goes around a part of the small intestine, which reduces the body's absorption of calories and nutrients.

Method 2

DISTAL gastric bypass is where the doctor removes part of the stomach. What is left is then connected to the last part of the small intestine. This method creates a small stomach pouch that does not hold much food.

Risks

There are many risks to consider with gastric bypass, including excessive bleeding, heart problems, gastrointestinal complications and infections. The risk for nutritional deficiencies is highest with DISTAL gastric bypass. Gastric bypass may also cause the food to pass too fast through the small intestine, creating nausea, weakness, sweating, faintness and diarrhea.

Diet

After gastric bypass surgery, you must make major changes to your diet, including long-term changes. It takes around 10 weeks to progress to eating solid food, and you must eat low-fat and low-sugar foods in order to avoid getting sick or damaging your digestive system.

Outlook

According to the University of Rochester Medical Center, patients lose weight for 18 to 24 months after gastric bypass surgery, and maintain around half of that weight loss 10 years later.
