Atherosclerosis

Atherosclerosis (Cholesterol Blockage in Arteries)

Atherosclerosis is a condition where fatty deposits (called plaques) build up inside blood vessels. These deposits are mainly made of cholesterol, calcium, and other substances found in the blood.

Over time, these plaques make the arteries narrow and hard. This reduces blood flow to important organs like the heart and brain. If a plaque suddenly breaks, it can form a clot and completely block the artery.

This is the main cause of heart attacks and strokes. It develops slowly over many years, often without symptoms until a major problem occurs. That’s why it is called a “silent disease.”

Risk factors include high cholesterol, smoking, diabetes, obesity, and lack of exercise. Prevention includes healthy eating, regular walking, and taking medicines when prescribed.
