Gastric Bypass Surgery at Hospital CMQ

Gastric Bypass Surgery

Gastric bypass surgery is a type of bariatric surgery or weight loss surgery. Is the most complex type of bariatric surgery. During the gastric bypass surgery, your physician makes changes to your stomach and small intestine to change the way they absorb and digest food.

How it works: the surgeon staples the stomach, creating a bag in the upper section that works as the main stomach. Subsequently, the small intestine is cut and joined with the stomach pouch created. This causes food to skip most of the stomach and upper small intestine. Gastric bypass aids weight loss by:

  • Restricting the amount of food that your stomach holds.
  • Limiting the number of calories and nutrients your body absorbs.
  • Changing your gut hormones, which help you feel fuller longer, contribute to appetite suppression and the reversal of obesity-caused metabolic syndrome.
