Gastric Bypass

Gastric BypassAlso known as the Roux-en-Y gastric bypass. The Gastric bypass surgery aims to surgically reroute the digestive tract so that food actually bypasses the stomach. In this type of surgery, 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 start feeling full even with less food. The food that you eat will no longer go into some parts of your stomach and the small intestine that break down food. Because of this, your body will not absorb all of the calories from the food you eat.

What to Expect?

In this surgery, you will be administered general anaesthesia. There are two steps that are during gastric bypass surgery:

  • The first step makes your stomach smaller. Your surgeon will use staples to divide your stomach into a small upper section and a larger bottom section. The top section of your stomach which is called the pouch is where the food you eat will go. The pouch is just about the size of a walnut. It will hold only about 1 ounce of food.

  • The second step is the bypass. In this step, your surgeon will connect a small part of your small intestine to a small hole in your pouch. The food you eat will now travel from the pouch into this new opening right into your small intestine. Because of this, your body will absorb fewer calories.

Open Surgery and Laparoscopy
The Gastric bypass surgery can be done in two ways. With open surgery, your surgeon will make a large incision to open up your belly while in laparoscopy, four to six small cuts are made on your stomach to use a small camera and create a bypass inside.

Advantages of laparoscopy over open surgery include:
  • Shorter hospital stay and quicker recovery.
  • Less pain.
  • Smaller scars and a lower risk of getting a hernia or infection.
  • This surgery takes about 2 to 4 hours.
