Bypass surgery is basically a common term used to describe two very different types of surgery. The first is a heart surgery, formally known as Coronary Artery Bypass Graft surgery. This surgery is performed to “bypass” blocked arteries that feed the heart, allowing the heart to receive the blood it needs to function. You may also hear this procedure referred to as a CABG, pronounced cabbage.
Some types of weight loss surgery are also referred to as bypass surgery. Weight loss surgeries that decrease the amount of calories that body can absorb by “bypassing” part of the small intestine fall into this category. Roux-en-y is an example of this type of weight loss surgery, as is the duodenal switch procedure.
