Learn more about High Cholesterol

Cholesterol is a waxy, fat-like substance that travels through the blood. In and of itself, cholesterol isn’t bad. It actually helps create the outer coating of our cells and aids the body in making vitamin D and certain hormones.

Your body makes the cholesterol it needs. But you also get it in your diet (for example, full-fat dairy products, fried foods and fatty meat). Too much cholesterol can be dangerous. That’s because over time cholesterol and fat can build in the inner walls of the arteries that supply blood to the heart. This can cause a narrowing of the arteries (see atherosclerosis), which is a major cause of heart disease.

If you have high cholesterol, you’re certainly not alone. It will affect roughly half of all men and a third of all women at some point in their lives. The good news is that high cholesterol is often preventable and treatable. Adopting a healthy diet, getting regular exercise and, in some cases, taking medication can go a long way to help lower your cholesterol and protect your heart.
