Gastric bypass is surgery that is done to help you lose weight. After the surgery, you will not be able to eat as much as before, and your body will not absorb all the calories from the food you eat.

This surgery helps you lose weight by changing how your stomach and small intestine handle the food you eat.

• After the surgery, your stomach will be smaller. You will feel full or satisfied with less food.
• The food you eat will no longer go into some parts of your stomach and small intestine that break down food. Because of this, your body will not absorb all the calories from the food you eat.

You will receive general anesthesia before this surgery. This will make you unconscious and unable to feel pain.
