A bypass surgery is carried out to clear the blockages in the arteries. When a person's arteries get blocked, the condition is known as coronary artery disease. To rectify this problem and to clear out all the blockages, the doctors carry out a bypass surgery on the patient. Before you enter any hospital to get the bypass surgery done, do enough study, research and counseling so that you are well informed about the procedure and you feel comfortable with every step.

The arteries in your body are responsible for carrying the blood from the heart to the rest of the body. The main artery that carries the blood out of the heart is known as the aorta. There are two blood vessels that branch out of the base of this aorta. These blood vessels are the right and left coronary arteries, both of which have many branches.

When the size of plaque in a person artery rises by 70 percent or more of its regular size, the artery gets blocked. In the case of a lesser severe blockage, the best solution to improve it is with angioplasty a stent. A very small sized balloon is attached to the affected area and inflated slowly. A tube called a stent is used to keep the arteries open.

Cases in which the blockage in the arteries is very severe, the doctors usually recommend the patient to undergo a bypass surgery. The severe blockage in the arteries causes a heart attack. In such cases, when the bypass is performed, a fresh piece of blood vessel in threaded in the affected area by the surgeon, leading to the creation of a bridge over the blockages. If the other arteries in the heart are found to be blocked, the doctor may decide to rectify them as well.

When the blockages in three of the arteries have been improved, it is known as a triple bypass surgery. Furthermore, if four arteries have been improved, the procedure will be called a quadruple bypass surgery.

To perform a bypass surgery, a blood vessel is taken from the leg or chest of the patient. Our bodies have many superfluous blood vessels that can be taken out without causing any harm to the rest of the body. A bypass surgery has become very common in today's era. Blocked arteries are efficiently corrected by deflecting the blood in and around the blocked area.

It is very important to get a bypass surgery done if you have blocked arteries, because if you continue with them, there is a huge risk to your life. The heart beats continuously throughout the day, pumping over 5 million gallons of blood into the body. It is essential to consult a doctor to prevent heart attacks and even sudden death.

Fatty foods and foods that are high in cholesterol are the main causes of blocked arteries. Also, for people above the age of fifty, the risk of blocked arteries is very high. Hence, it is always good to take prevention from the start itself.
