People in the United States are making progress on high cholesterol

About two thirds of US adults say they have had their cholesterol checked within the last 5 years.4

Most healthy adults should have their cholesterol checked every 4 to 6 years. Some people, such as those who have heart disease, diabetes, or a family history of high cholesterol, need to get their cholesterol checked more often.5
