Atherosclerosis is a potentially serious condition where arteries become cloggedwithfatty 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 tohave any symptoms at first, and many people may be unaware they have it, but it can eventually causelife-threatening problems such asheart attacks andstrokes if it gets worse.

However, the condition is largely preventable with a healthy lifestyle, and treatment can help reduce the risk of serious problems occurring.
