How Is High Blood Cholesterol Treated?

High blood cholesterol is treated with lifestyle changes and medicines. The main goal of treatment is to lower your low-density lipoprotein (LDL) cholesterol level enough to reduce your risk for coronary heart disease, heart attack, and other related health problems.

Your risk for heart disease and heart attack goes up as your LDL cholesterol level rises and your number of heart disease risk factors increases.

Some people are at high risk for heart attacks because they already have heart disease. Other people are at high risk for heart disease because they have diabetes or more than one heart disease risk factor.

Talk with your doctor about lowering your cholesterol and your risk for heart disease. Also, check the list to find out whether you have risk factors that affect your LDL cholesterol goal:

  • Cigarette smoking
  • High blood pressure (140/90 mmHg or higher), or you’re on medicine to treat high blood pressure
  • Low high-density lipoprotein (HDL) cholesterol (less than 40 mg/dL)
  • Family history of early heart disease (heart disease in father or brother before age 55; heart disease in mother or sister before age 65)
  • Age (men 45 years or older; women 55 years or older)

You can use the NHLBI 10-Year Risk Calculator to find your risk score. The score, given as a percentage, refers to your chance of having a heart attack in the next 10 years.

Based on your medical history, number of risk factors, and risk score, figure out your risk of getting heart disease or having a heart attack using the table below.

If You Have You Are in Category Your LDL Goal Is
Heart disease, diabetes, or a risk score higher than 20% I. High risk* Less than 100 mg/dL
Two or more risk factors and a risk score of 10–20% II. Moderately high risk Less than 130 mg/dL
Two or more risk factors and a risk score lower than 10% III. Moderate risk Less than 130 mg/dL
One or no risk factors IV. Low to moderate risk Less than 160 mg/dL

* Some people in this category are at very high risk because they’ve just had a heart attack or they have diabetes and heart disease, severe risk factors, or metabolic syndrome. If you’re at very high risk, your doctor may set your LDL goal even lower, to less than 70 mg/dL. Your doctor also may set your LDL goal at this lower level if you have heart disease alone.

After following the above steps, you should have an idea about your risk for heart disease and heart attack. The two main ways to lower your cholesterol (and, thus, your heart disease risk) include:

  • Therapeutic Lifestyle Changes (TLC). TLC is a three-part program that includes a healthy diet, weight management, and physical activity. TLC is for anyone whose LDL cholesterol level is above goal.
  • Medicines. If cholesterol-lowering medicines are needed, they’re used with the TLC program to help lower your LDL cholesterol level.

Your doctor will set your LDL goal. The higher your risk for heart disease, the lower he or she will set your LDL goal. Using the following guide, you and your doctor can create a plan for treating your high blood cholesterol.

Category I, high risk, your LDL goal is less than 100 mg/dL.*

Your LDL Level Treatment
If your LDL level is 100 or higher You will need to begin the TLC diet and take medicines as prescribed.
Even if your LDL level is below 100 You should follow the TLC diet to keep your LDL level as low as possible.

* Your LDL goal may be set even lower, to less than 70 mg/dL, if you’re at very high risk or if you have heart disease. If you have this lower goal and your LDL is 70 mg/dL or higher, you’ll need to begin the TLC diet and take medicines as prescribed.

Category II, moderately high risk, your LDL goal is less than 130 mg/dL

Your LDL Level Treatment
If your LDL level is 130 mg/dL or higher You will need to begin the TLC diet.
If your LDL level is 130 mg/dL or higher after 3 months on the TLC diet You may need medicines along with the TLC diet.
If your LDL level is less than 130 mg/dL You will need to follow a heart healthy diet.

Category III, moderate risk, your LDL goal is less than 130 mg/dL.

Your LDL Level Treatment
If your LDL level is 130 mg/dL or higher You will need to begin the TLC diet.
If your LDL level is 160 mg/dL or higher after 3 months on the TLC diet You may need medicines along with the TLC diet.
If your LDL level is less than 130 mg/dL You will need to follow a heart healthy diet.

Category IV, low to moderate risk, your LDL goal is less than 160 mg/dL.

Your LDL Level Treatment
If your LDL level is 160 mg/dL or higher You will need to begin the TLC diet.
If your LDL level is 160 mg/dL or higher after 3 months on the TLC diet You may need medicines along with the TLC diet.
If your LDL level is less than 160 mg/dL You will need to follow a heart healthy diet.

Lowering Cholesterol Using Therapeutic Lifestyle Changes

TLC is a set of lifestyle changes that can help you lower your LDL cholesterol. The main parts of the TLC program are a healthy diet, weight management, and physical activity.

The TLC Diet

With the TLC diet, less than 7 percent of your daily calories should come from saturated fat. This kind of fat is found in some meats, dairy products, chocolate, baked goods, and deep-fried and processed foods.

No more than 25 to 35 percent of your daily calories should come from all fats, including saturated, trans, monounsaturated, and polyunsaturated fats.

You also should have less than 200 mg a day of cholesterol. The amounts of cholesterol and the types of fat in prepared foods can be found on the foods' Nutrition Facts labels.

Foods high in soluble fiber also are part of the TLC diet. They help prevent the digestive tract from absorbing cholesterol. These foods include:

  • Whole-grain cereals such as oatmeal and oat bran
  • Fruits such as apples, bananas, oranges, pears, and prunes
  • Legumes such as kidney beans, lentils, chick peas, black-eyed peas, and lima beans

A diet rich in fruits and vegetables can increase important cholesterol-lowering compounds in your diet. These compounds, called plant stanols or sterols, work like soluble fiber.

A healthy diet also includes some types of fish, such as salmon, tuna (canned or fresh), and mackerel. These fish are a good source of omega-3 fatty acids. These acids may help protect the heart from blood clots and inflammation and reduce the risk of heart attack. Try to have about two fish meals every week.

You also should try to limit the amount of sodium (salt) that you eat. This means choosing low-salt and "no added salt" foods and seasonings at the table or while cooking. The Nutrition Facts label on food packaging shows the amount of sodium in the item.

Try to limit drinks with alcohol. Too much alcohol will raise your blood pressure and triglyceride level. (Triglycerides are a type of fat found in the blood.) Alcohol also adds extra calories, which will cause weight gain.

Men should have no more than two drinks containing alcohol a day. Women should have no more than one drink containing alcohol a day. One drink is a glass of wine, beer, or a small amount of hard liquor.

For more information about TLC, go to the National Heart, Lung, and Blood Institute’s (NHLBI’s) "Your Guide to Lowering Your Cholesterol With TLC."

Weight Management

If you’re overweight or obese, losing weight can help lower LDL cholesterol. Maintaining a healthy weight is especially important if you have a condition called metabolic syndrome.

Metabolic syndrome is the name for a group of risk factors that raise your risk for heart disease and other health problems, such as diabetes and stroke.

The five metabolic risk factors are a large waistline (abdominal obesity), a high triglyceride level, a low HDL cholesterol level, high blood pressure, and high blood sugar. Metabolic syndrome is diagnosed if you have at least three of these metabolic risk factors.

Physical Activity

Routine physical activity can lower LDL cholesterol and triglycerides and raise your HDL cholesterol level.

People gain health benefits from as little as 60 minutes of moderate-intensity aerobic activity per week. The more active you are, the more you will benefit.

For more information about physical activity, go to the U.S. Department of Health and Human Services' "2008 Physical Activity Guidelines for Americans," the Health Topics Physical Activity and Your Heart article, and the NHLBI's "Your Guide to Physical Activity and Your Heart."

Cholesterol-Lowering Medicines

In addition to lifestyle changes, your doctor may prescribe medicines to help lower your cholesterol. Even with medicines, you should continue the TLC program.

Medicines can help control high blood cholesterol, but they don’t cure it. Thus, you must continue taking your medicine to keep your cholesterol level in the recommended range.

The five major types of cholesterol-lowering medicines are statins, bile acid sequestrants (seh-KWES-trants), nicotinic (nick-o-TIN-ick) acid, fibrates, and ezetimibe.

  • Statins work well at lowering LDL cholesterol. These medicines are safe for most people. Rare side effects include muscle and liver problems.
  • Bile acid sequestrants also help lower LDL cholesterol. These medicines usually aren’t prescribed as the only medicine to lower cholesterol. Sometimes they’re prescribed with statins.
  • Nicotinic acid lowers LDL cholesterol and triglycerides and raises HDL cholesterol. You should only use this type of medicine with a doctor’s supervision.
  • Fibrates lower triglycerides, and they may raise HDL cholesterol. When used with statins, fibrates may increase the risk of muscle problems.
  • Ezetimibe lowers LDL cholesterol. This medicine works by blocking the intestine from absorbing cholesterol.

While you’re being treated for high blood cholesterol, you’ll need ongoing care. Your doctor will want to make sure your cholesterol levels are controlled. He or she also will want to check for other health problems.

If needed, your doctor may prescribe medicines for other health problems. Take all medicines exactly as your doctor prescribes. The combination of medicines may lower your risk for heart disease and heart attack.

While trying to manage your cholesterol, take steps to manage other heart disease risk factors too. For example, if you have high blood pressure, work with your doctor to lower it.

If you smoke, quit. Talk with your doctor about programs and products that can help you quit smoking. Also, try to avoid secondhand smoke. If you’re overweight or obese, try to lose weight. Your doctor can help you create a reasonable weight-loss plan.
