Gastric bypass surgery is a type of bariatric, or weight loss, surgery. During gastric bypass surgery, your physician makes changes to your stomach and small intestine to change the way they absorb and digest food.
Gastric bypass aids weight loss by:
- Restricting the amount of food that your stomach holds
- Limiting the amount 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.
