Coronary Artery Bypass Grafting is a medical term used for treatment of coronary heart disease. Bypass surgery is the term used in colloquial terms for this surgery. Doctors recommend bypass surgery for patients who have obstructed blood flow in their coronary artery. This obstructed blood flow is a result of atherosclerosis and arteriosclerosis.
Deposition of a substance called plaque on the arterial walls hardens and narrows the arteries. This leads to arteriosclerosis. There is calcium deposition on the arterial wall and loss of elasticity in case of a person suffering from arteriosclerosis.

Blood flow gets facilitated in the clogged arteries through bypass surgery. This also allows easy transmission of oxygen to the heart.
The bypass surgery procedure begins with an analgesic being administered to the patient for making him unconscious. An opening is made into the chest to enable the surgeon to examine the heart. Blood vessels from another body-part are attached to the coronary artery for grafting. Heparin(injectable for thinning blood) is then given to the patient to prevent blood clotting. The bypass surgery usually takes three - six hours.
The recuperation pace of each patient varies from the other. But in most cases, the patients have to stay back in the hospital for seven days after the surgery.
Post surgery, the patient is advised to follow a healthy diet which includes a balance of whole grains, vegetables, fruits, legumes, low fat dairy products, proteins etc. Teaming a healthy diet with regular exercise will help the patient to lead a healthy life and also eliminate the need of repeat bypass or an angioplasty.
The patient can return to his daily routine once the recovery period is over.
