What is Involved in a Gastric Bypass Surgery?

Gastric bypass is the surgery which helps you reduce your weight by changing the way your stomach and small intestine handles the food when eaten by you. After the surgery is done, your stomach will get smaller, and it will feel full even after having a lesser amount of food.

Foods that you will intake after a gastric bypass surgery will not go into some parts of your stomach as well as the small intestine. So, whatever you eat, your body won’t get all the calories from the food.

How is the procedure done?

The procedure will take be done after you are sedated with general anesthesia. So, you are going to be asleep and won’t feel any pain.

This procedure is done in two steps:

  • In the first step, your stomach will be made smaller. Surgeons will use staples and divide your stomach into two parts, one small upper section, and the other a larger bottom section. When you eat your food, it will go to the smaller section of the stomach, called as a pouch. The pouch is of very small size, around the size of a walnut and it can hold only 1 ounce (28 grams) of food in it. Therefore, you will always feel full and eat less.
  • In the second step, the surgeon will do the bypass. The pouch and the small intestine will be connected with small holes. So, the foods you are going to eat will travel from the pouch to your small intestine through the bypass. Therefore, fewer calories will be absorbed by your body.

  • Laparoscopic

There are many advantages of laparoscopic surgery, for example, quicker recovery and a shorter stay in the hospital, less pain, and small scars have a lesser chance of getting infection and hernia.
