Restrictive with Malabsorptive
This procedure
restricts both food intake and the amount of calories and nutrients the body absorbs. In addition to creating a stomach
pouch, the surgery disrupts the body's normal digestive process. As a result, food bypasses a large part of the stomach
and most of the small intestine.
Roux-En-Y Gastric Bypass:
A Combined Approach
The Roux-En-Y Gastric
Bypass procedure combines restrictive and malabsorptive procedure and is the most popular technique, comprising 75 percent
of bariatric surgical procedures. During the Roux-En-Y procedure, stapling is used to create a small, upper-stomach
pouch, which restricts the amount of food to be consumed. A portion of small bowel is bypassed, thus delaying food from
mixing with digestive juices to avoid complete calorie absorption. In most cases, patients report an early sense of
fullness, combined with a sense of satisfaction, that reduces the desire to eat.
Gastric bypass patients typically
lose 60 percent of excess weight in the first year following surgery. Many health problems (back pain, sleep, and depression)
improve or are resolved following surgery.
A comprehensive clinical review of bariatric surgery data showed that
patients (22,094 patients) who underwent a bariatric surgical procedure experienced complete resolution or improvement of
their co-morbid conditions, including diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea.
