Gastric Bypass

Bypass gástrico

Also: Derivación gástrica (regional variant)

What it means

Gastric bypass is surgery that helps a person lose weight by changing how the stomach and small intestine handle food. First the surgeon uses staples to divide the stomach into a small upper section, called the pouch, and a larger bottom section, so the person feels full with less food. Then the surgeon connects a part of the small intestine to a small hole in the pouch; food bypasses part of the small intestine, so the body absorbs fewer calories. It can be done as open surgery or with a laparoscope, a scope with a tiny camera, and the person has general anesthesia. It is also called Roux-en-Y gastric bypass. Gastric bypass is major surgery with many risks, and it is not a quick fix for obesity.
