Bariatric surgery is popularly known as weight loss surgery , includes a variety of procedures performed on people who have obesity. Weight loss is achieved by reducing the size of the stomach with a gastric band or through removal of a portion of the stomach (sleeve gastrectomy orduodenal switch) or by resecting and re-routing the small intestine to a small stomach pouch (gastric bypass surgery).
Long-term studies show the procedures cause significant long-term loss of weight, recovery from diabetes, improvement in cardiovascular risk factors, The U.S. National Institutes of Health recommends bariatric surgery for obese people with a body mass index (BMI) of at least 40, and for people with BMI 35 and serious coexisting medical conditions such as diabetes
There are four types of operations that are commonly offeredRoux-en-Y gastric bypass (RYGB), biliopancreatic diversion with a duodenal switch (BPD-DS), and vertical sleeve gastrectomy (VSG). It the doctor who has to decide which is the best surgical option considering the patients weight, height, age , other disease and patients habits. Based on these the benefits and risks of each type of surgery is evaluated. Other factors to consider include the patient's BMI, eating habits, health conditions related to obesity, and previous stomach surgeries.
This surgery restricts food intake & also decreases how food is absorbed. Food intake is limited by a small pouch that is similar in size to the pouch created . Also, sending food directly from the pouch into the small intestine affects how the digestive tract absorbs food.
This is usually referred to as a "duodenal switch," is a complex bariatric surgery that includes three features. One feature is to remove a large part of the stomach. This step makes patients feel full sooner when eating . Feeling full sooner encourages patients to eat less. Another feature is re-routing food away from much of the small intestine to limit how the body absorbs food. The third feature changes how bile and other digestive juices affect the body's ability to digest food .
AGB works mainly by decreasing food intake. Food intake is reduced by placing a small bracelet-like band around the top of the stomach to restrict the size of the opening from the throat to the stomach. The surgeon can then control the size of the opening with a circular balloon inside the band. This balloon can be inflated or deflated with saline solution to meet the needs of the patient.
This surgery restricts food intake and decreases the amount of food used. Most of the stomach is removed during this surgery.
