Meaning of Bypass Surgery

Bypass surgery is exactly what its name suggests; it is a surgery that bypasses something. There are two main types of bypass surgery: coronary artery bypass surgery and gastric bypass surgery. However, the two are completely different.

Coronary artery bypass surgery, also known as coronary artery bypass operation or coronary artery bypass graft (CABG, pronounced “cabbage”) surgery, is a surgical procedure that is conducted to bypass the a section of a blocked artery. Here a piece of artery or vein is take from another part of the body, and is grafted to restore blood flow to where the blocked artery was supposed to provide the blood flow.

Coronary artery bypass surgery is a life-saving surgery that is performed to relieve angina and reduce the risk of death from coronary artery disease. Angina is the sensation of chest pain, pressure, or squeezing, that commonly occurs due to obstruction or spasm of the coronary arteries, that hamper blood flow to the heart.

Gastric bypass surgery is a type of surgery in which the stomach is divided into two parts: a small upper pouch and a much larger lower “remnant” pouch. Then the small intestine is rearranged to connect to both the pouch. This surgery is mainly done to reduce the functional volume of the stomach, which leads to people eating less. It also leads to an altered physiological and physical response to food. This type of surgery is conducted to treat morbid obesity, type 2 diabetes, hypertension, sleep apnea, and other comorbid conditions.

Bypass surgery may also be conducted the femoral arteries in the groin, or the popliteal arteries behind the knee, as well as any other arteries that may be affected by blockage.
