Bariatric surgery (weight-loss surgery) includes a variety of procedures performed on people who are obese. It is performed by the surgeon using minimal invasive techniques ( Bariatric surgery).
There are several different types of Bariatric surgery, or surgery done on the stomach and/or intestines to alter the normal digestive process, which in turn helps people lose weight. Each of the various types of bariatric surgery has its own advantages and disadvantages. The most popular operations being performed today are Laparoscopic Gastric bypass, Sleeve Gastrectomy and Laparoscopic adjustable gastric banding.
In Gasrtic bypass part of the stomach is stapled and becomes unusable. Then the smaller portion of the stomach is connected to the intestine. Because their stomachs have a smaller capacity for food, patients who have a gastric bypass will not be inclined to eat as much as they did prior to their surgery; when they do eat, they feel full much sooner than previously.
The Adjustable gastric banding, also known as the Lap-Band, is actually a band that is surgically inserted around the top part of the stomach to create a small pouch in the upper stomach. This procedure decreases the stomach’s capacity to take in food, and also reduces the patient’s desire for food.
The Sleeve gastrectomy is a procedure that restricts the food intake of the patient. Here the surgeon uses staples to make a “smaller stomach” in the upper part of the stomach.
