Gastric bypass surgery
Gastric Bypass Surgery
Gastric bypass surgery (pronounced: gas-trick by-pass sur-ger-y) is a type of weight loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine. This procedure is performed to treat obesity.
Etymology
The term "gastric bypass" originates from the Greek word "gaster" meaning stomach, and the English word "bypass" meaning to avoid something. The term refers to the surgical procedure that allows food to bypass a part of the stomach and the small intestine.
Procedure
During gastric bypass surgery, the surgeon makes a small incision in the abdomen. The top of the stomach is sealed off from the rest of the stomach, forming a pouch. The surgeon then connects a section of the small intestine to the pouch. This allows food to bypass a portion of the stomach and the upper part of the small intestine, reducing the amount of calories and nutrients the body absorbs.
Risks and Complications
Like any major surgery, gastric bypass surgery carries risks, including infection, bleeding, and blood clots. Long-term complications may include malnutrition, gallstones, and ulcers.
