Gastric Bypass

Gastric bypass and other types of weight-loss surgery — also called bariatric or metabolic surgery — involve making changes to your digestive system to help you lose weight.
Bariatric surgery is done when diet and exercise haven’t worked or when you have serious health problems because of your weight. Some weight-loss procedures limit how much you can eat. Others work by reducing the body’s ability to absorb fat and calories. Some procedures do both.
While bariatric surgery can offer many benefits, all forms of weight-loss surgery are major procedures that can pose risks and side effects. Also, you must make permanent healthy changes to your diet and get regular exercise to help ensure the long-term success of bariatric surgery.

What Is Gastric Bypass?

Gastric bypass surgery is an operation that shrinks the stomach to reduce the calories a patient takes and it makes the patient lose weight. The stomach is disconnected on the top part and made a small porch first. Then, a loop of the small intestine is brought up and connected to this porch. In that way, the surgeon reroutes the GI (gastrointestinal) tract. Consequently, It is known that surgeons bypass about 95% of the stomach in gastric bypass surgery.
