  1. First, the stomach is cut to create a very small upper pouch and a larger lower pouch and second, the small intestine is cut.
  2. The more distant portion of the small intestine is connected to the small stomach pouch. Initially, this pouch holds about an ounce of food, causing a feeling of fullness after consuming a very small amount. In time, the pouch stretches to hold about one cup of food at each meal.
  3. The remaining larger lower stomach pouch, which does not receive food anymore, is sutured to the small intestine and is needed to deliver digestive juices and hormones.
  4. Since food bypasses the majority of the stomach, as well as the upper small intestine, the body absorbs fewer calories from the food.
  5. Gastric bypass decreases appetite and improves metabolism by altering the release of various hormones.
  6. After gastric bypass surgery, patients feel full faster and must eat much less at any given time.

Laparoscopic Surgery for Gastric Bypass
Gastric bypass surgery is often performed by laparoscope. Laparoscopic procedures consist of multiple small incisions. Five to six incisions are normally used in gastric bypass. An "open" procedure, which is used less often, uses a single, long cut to provide the surgeon access to the abdomen.

In a laparoscopic surgery, a camera is used to view the abdomen via the incisions. Small instruments are then used to perform the surgery through the multiple access points.

There are benefits to choosing laparoscopic surgery over an open procedure. Laparoscopic procedures lead to fewer wound complications such as risk of infection and patients usually experience less pain following surgery.

Laparoscopy patients are also able to leave the hospital sooner and get moving again more quickly than patients who've had an open procedure.

Some surgeons still perform gastric bypass via open surgery based on preference and their experience level with the particular procedure.

You may wish to talk to multiple surgeons to discuss the pros and cons of each kind of procedure before making any final decisions about your surgery. While it is your personal option to choose between a surgeon who performs open or laparoscopic procedures, there are times when a laparoscopic procedure becomes an open procedure on the table due to complications or difficulties.

Gastric bypass surgery is a major surgery with potentially serious postoperative complications. Decision to have the surgery should be the last step. While weight loss surgery changes lives in great ways, it also brings with it a huge change in the lifestyle and in the eating habits.
