One in every six adult Americans has high cholesterol. Too much cholesterol in the blood is one of the main risk factors for heart disease and stroke—two leading causes of death in the United States. One way to prevent these diseases is to detect high cholesterol and treat it when it is found.
What is cholesterol?
Cholesterol is a waxy, fat-like substance that your body needs. But when you have too much in your blood, it can build up on the walls of your arteries and form blockages. This can lead to heart disease, heart attack, and stroke.
There are two kinds of cholesterol: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). HDL is also called “good” cholesterol. LDL is called “bad” cholesterol. When we talk about high cholesterol, we are talking about “bad” LDL cholesterol.
Seventy-one million American adults have high cholesterol, but only one-third of them have the condition under control. Since September is National Cholesterol Education Month, now is an ideal time to check your cholesterol and take steps to lower it if it is high.
What role does screening play?
Screening is the key to detecting high cholesterol. Because high cholesterol does not have symptoms, many people do not know that their cholesterol is too high. Your doctor can do a simple blood test to check your cholesterol level.
The National Cholesterol Education Program recommends that adults aged 20 years or older have their cholesterol checked every 5 years.
You may need to have your cholesterol checked more often if any of the following statements apply to you:
• Your total cholesterol is 200 mg/dL or higher.
• You are a man older than age 45 or a woman older than age 50.
• Your HDL cholesterol is lower than 40 mg/dL.
• You have other risk factors for heart disease and stroke.
How can you prevent or treat high cholesterol?
Make therapeutic lifestyle changes by
• Eating a healthy diet. Avoid saturated fats and trans fats, which tend to raise cholesterol levels. Other types of fats, such as polyunsaturated fats, can actually lower blood cholesterol levels. Eating fiber also can help lower cholesterol.
• Exercising regularly. Physical activity can help lower cholesterol. The Surgeon General recommends that adults engage in moderate-intensity exercise for 2 hours and 30 minutes every week.
• Maintaining a healthy weight. Being overweight or obese can raise your cholesterol levels. Losing weight can help lower your cholesterol.
• Not smoking. If you smoke, quit as soon as possible.
Be sure to follow your doctor’s instructions and stay on your medications, if prescribed, to control your cholesterol.
The Million Hearts® initiative is a national effort to prevent 1 million heart attacks and strokes in the United States by 2017, by bringing together communities, health systems, nonprofit organizations, federal agencies, and private sector partners. Million Hearts focuses on:
(1) Improving the “ABCS” of cardiovascular health—Aspirin when appropriate, Blood pressure control, Cholesterol management, and Smoking cessation; and
(2) Empowering Americans to make healthy choices such as preventing or quitting tobacco use and reducing salt (sodium) and trans fat consumption.
