Prevention and treatment can drastically reduce risk for heart disease.

Think of a garden hose. It’s fairly flexible and, if it’s clear of dirt and debris, the water passes through fairly easily. But what happens if gunk or thick paste starts sticking to the inside of the hose? It would make it difficult for the once free-flowing water to move.

This is somewhat similar to what happens when the arteries in our bodies narrow or become hardened. This hardening and narrowing of the arteries—called atherosclerosis—makes it harder for blood to flow through them. 

Atherosclerosis is fairly common, especially as we age. It happens when fat and cholesterol in the blood form plaque which can build up inside the artery walls. If this plaque begins to block the arteries, it can slow and limit the flow of blood to your organs. When this happens it can cause serious problems in blood vessels throughout the body, including heart attack, stroke, peripheral arterial disease and kidney disease.

Many people don’t know they have atherosclerosis until it starts causing health problems. That’s why it’s so important for you to make healthy choices every day and get regular cholesterol screenings. Doing so can help you prevent problems down the line.

Use this condition center to learn more about atherosclerosis, create a list of questions to ask your health care provider and get practical tips.
