Bypass surgery, also known as Coronary Artery Bypass Grafting (CABG), is a procedure to replace damaged or blocked arteries in the heart with blood vessels from another part of the body.

Patients with severe coronary artery disease, where the arteries are significantly narrowed or blocked, may need bypass surgery to improve blood flow to the heart.

A surgeon takes a healthy blood vessel from your leg, arm, or chest and connects it to the blocked coronary artery, bypassing the blocked section to improve blood flow.

Risks include infection, bleeding, heart attack, stroke, and reactions to anaesthesia, though serious complications are rare.

The surgery typically lasts between 3 to 6 hours, depending on the number of arteries being bypassed and the patient’s condition.

The surgery duration varies based on the complexity but typically lasts between 2 to 6 hours.

Symptoms may include fatigue, bone pain, muscle weakness, mood changes, and frequent infections.

Treatment involves vitamin D3 supplementation through oral tablets or injections, depending on the severity of the deficiency.

Yes, diets low in vitamin D-rich foods like fatty fish, fortified dairy products, and egg yolks can lead to vitamin D3 deficiency.

Frequency depends on individual risk factors and health conditions. Consult your healthcare provider for personalized advice.

The test involves a simple blood draw with minimal risks, such as slight bruising at the puncture site.
