Over 30 percent of adults in the United States have high cholesterol, which typically means their total cholesterol is at or above 200 mg/dL. Cholesterol is a waxy substance found in your body’s cells. Your liver makes it, and you do need some amount of cholesterol for specific body functions. The problem is when you have too much cholesterol. More specifically, elevated LDL cholesterol is typically concerning.
Not sure if you have high cholesterol? Ask your primary care doctor about having a cholesterol screening. Healthy adults should seek a cholesterol test about every four to six years so they can know their risk. If you have abnormal results or have many risk factors for heart disease, your doctor may recommend more frequent testing.
