Gastric Bypass

Gastric bypass or Roux in Y gastric bypass (RYGB) is a type of weight loss surgery that works by making the stomach smaller and the digestive system shorter. The gastric bypass divides the stomach into a small upper pouch and a larger remnant pouch and then arranges the small intestine to allow both pouches to stay connected to it accordingly.

The surgery makes the stomach smaller in capacity, which reduces the amount of food that you can eat, The food bypasses a section of the small intestine (aprox. 13-17 feet) resulting in lesser calorie absorption by the body resulting in weight loss.

Gastric Bypass is one of the final steps one can take to combat weight problems. Its results are immediate, long lasting and beneficial especially when accompanied with a balanced and sustained lifestyle changes.
