(NewsNation) — Cholesterol is a waxy substance that’s found in the blood, which the body needs in order to build healthy cells. High levels of cholesterol, however, can increase the risk of heart disease.
With high cholesterol, fats and other substances, collectively known as plaque, can build up in the arteries. When plaque continues to build up over time, arteries can become narrow or get clogged, making it harder for blood to flow.
According to Johns Hopkins Medicine, about 71 million Americans have high cholesterol.
High cholesterol is often the result of lifestyle factors like not getting enough exercise and eating a diet high in saturated and trans fats, but some health conditions like diabetes and hypothyroidism can lead to cholesterol issues. A blood test is the only way to find out if you have it, according to the Mayo Clinic.
To prevent high cholesterol and lead a heart-healthy lifestyle, some good habits include limiting sodium and added sugars in your diet, getting at least 30 minutes of exercise in a few days a week and drinking less alcohol.
