It's important to get your cholesterol checked regularly. Too much cholesterol in your blood can cause a heart attack or a stroke.
The good news is that it’s easy to get your cholesterol checked. If your cholesterol is high, you can take steps to lower it — like eating healthy, getting more physical activity, and taking medicine if your doctor recommends it.
The general recommendation is to get your cholesterol checked every 4 to 6 years. Some people may need to get their cholesterol checked more often depending on their risk of heart disease.
For example, high cholesterol can run in families. If someone in your family has high cholesterol or takes medicine to control cholesterol, you might need to get tested more often. Talk to your doctor about what’s best for you.
Cholesterol is a waxy material that’s found naturally in your blood. Your body makes cholesterol and uses it to do important things, like making hormones and digesting fatty foods.
If you have too much cholesterol in your body, it can build up inside your blood vessels and make it hard for blood to flow through them. Over time, this can lead to heart disease.
Most people who have high cholesterol don't have any signs or symptoms. That's why it's so important to get your cholesterol checked.
Your doctor will check your cholesterol levels with a blood test called a lipid profile. A nurse will take a small sample of blood from your finger or arm for this test.
There are other blood tests your doctor can do to check cholesterol, but a lipid profile gives the most information.
If you get a lipid profile test, the results will show a few numbers. A lipid profile measures:
Total cholesterol is a measure of all the cholesterol in your blood. It's based on the LDL, HDL, and triglycerides numbers.
LDL cholesterol is a “bad” (unhealthy) type of cholesterol that can block your arteries — so a lower level is better for you. Having a high LDL level can increase your risk for heart disease.
HDL cholesterol is the “good” type of cholesterol that helps take LDL cholesterol out of your arteries — so a higher level is better for you. Having a low HDL cholesterol level can increase your risk for heart disease.
Triglycerides are a type of fat in your blood that can increase your risk for heart attack and stroke.
The results of your lipid profile test may also show your non-HDL cholesterol number. Non-HDL cholesterol is LDL cholesterol and the other “bad” types of cholesterol. In other words, it’s your total cholesterol minus your HDL cholesterol. Having a high non-HDL level can increase your risk for heart disease.
Causes of high LDL (bad) cholesterol or low HDL (good) cholesterol levels include:
As your LDL cholesterol gets higher, so does your risk of heart disease. Take these steps to lower your cholesterol and reduce your risk of heart disease:
Find out what your cholesterol levels are. If your cholesterol levels are unhealthy or you're at risk for heart disease, take steps to control your cholesterol levels.
Call your doctor’s office or health center to schedule the test. Be sure to ask for a complete lipid profile — and find out what instructions you’ll need to follow before the test. For example, you may need to fast (not eat or drink anything except water) for 9 to 12 hours before the test.
Use these questions to ask your doctor about cholesterol . Take them to your next checkup — you can print them out or pull them up on a smartphone or tablet.
Under the Affordable Care Act, insurance plans must cover cholesterol testing. Depending on your insurance plan, you may be able to get your cholesterol checked at no cost to you. Check with your insurance company to find out more.
Medicare may also cover cholesterol testing at no cost. If you have Medicare, learn about Medicare coverage for cholesterol testing.
If you don't have insurance, you may still be able to get free or low-cost cholesterol testing. Find a health center near you and ask about cholesterol testing.

Getting active can help you lose weight, lower your LDL (bad) cholesterol, and raise your HDL (good) cholesterol.
