Atherosclerosis & Arteriosclerosis


Atherosclerosis, occurs when arteries (vessels carrying oxygen-rich blood to the brain and other body parts) become clogged up by fatty substances (also called plaques or atheromas), such as cholesterol. Plaques or atheromas cause arteries to harden and narrow-up, resulting in restricted blood flow or plaque raptures, which then clots the blood. When this happens, it can block blood flow and result in a stroke and heart attack. Some experts say that Atherosclerosis itself is not the disease, but a risk factor.

Atherosclerosis is commonly confused with Arteriosclerosis. Arteriosclerosis has to do with the walls of the arteries thickening and losing its elasticity. Both may result in the same complications of stroke, heart attack and others.(click to see detailed illustration)

These include smoking, a high-fat diet, a lack of exercise, being overweight or obese, having either type 1or type 2 diabetes, having high blood pressure (hypertension) or having high cholesterol.

Treatment and Prevention of Atherosclerosis
There is treatment available for Atherosclerosis, and it aims to prevent Atherosclerosis from degenerating into a heart attack. Your doctor will take you through some medications. Additionally, lifestyle changes such as eating a healthier diet and increasing exercise can help you minimize the risks.
