Atherosclerosis is a potentially serious condition where arteries become clogged with fatty substances called plaques, or atheroma.

These plaques cause the arteries to harden and narrow, restricting the blood flow and oxygen supply to vital organs, and increasing the risk of blood clots that could potentially block the flow of blood to the heart or brain.

Atherosclerosis doesn’t tend to have any symptoms at first, and many people may be unaware they have it, but it can eventually cause life-threatening problems such as heart attacks and strokes if it gets worse.
