Surgery on the stomach and/or intestines to help a
person with extreme obesity lose weight. Bariatric surgery is an option for people
who have a body mass index (BMI) above 40. Surgery is also an option for people
with a BMI between 35 and 40 who have health problems like type 2 diabetes or heart
disease.
There are two main types of bariatric surgery,
adjustable gastric banding
and gastric bypass.
In adjustable gastric banding, insertion of a band restricts
the size of the opening from the esophagus to the stomach. The size of the opening
to the stomach determines the amount of food that can be eaten. The size of the
opening can be controlled by the surgeon by inflating or deflating the band through
a port that is implanted beneath the skin on the abdomen. The band can be removed
at any time.
In contrast to gastric banding, gastric bypass (sometimes referred to as roux-en-Y
gastric bypass) is a permanent reduction in the size of the stomach. The proximal
portion of the stomach is used to create an egg-sized pouch that is connected to
the intestine in a location that bypasses about 2 feet of normal intestine. The
amount of food that can be eaten is limited by the size of the pouch and the size
of the opening between the pouch and the intestine.
