Cholesterol is a type of fat (lipid). It’s needed for many body functions and made by your body. It also comes from food you eat (meat and dairy products). High cholesterol means that you have too much LDL cholesterol or “bad” cholesterol in your blood. LDL cholesterol is considered the “bad” cholesterol because it can lead to the buildup of fat in the artery walls of your heart. This can increase your risk of coronary artery disease (CAD), heart attack, and stroke.
HDL cholesterol can be thought of as the “good” cholesterol because a healthy level may help protect against heart attack and stroke. Good cholesterol helps clear out the cholesterol your body doesn’t need.
What causes it?
Doctors can’t usually say for sure what may cause high cholesterol. But many things can make it more likely, such as:
- Having family who have or had high cholesterol
-
Eating too much food that has saturated fat, like:
- Red meat
- Process meat like bacon or hot dogs
- Full-fat dairy
- Organ meats like liver
What are the symptoms?
High cholesterol doesn’t cause symptoms in most people. That’s why it’s important to get a routine blood test to get checked. A blood test is the only way to know your cholesterol levels.
How is high cholesterol treated?
The goal of treatment is to reduce your risk of having a heart attack or stroke. The two main types of treatment for high cholesterol are medicine and a heart-healthy lifestyle.
A heart-healthy lifestyle includes:
- Eating heart-healthy foods including healthier food with unsaturated fats.
- Staying at a weight that’s healthy for you. Talk to your primary care provider* (PCP) if you need help losing weight.
- Being active on most days of the week.
- Not smoking or vaping.
- Managing other health problems.
Medicines
Some people may need to take medicines called statins along with having a healthy lifestyle. Statins can reduce the risk of having a heart attack or stroke. Sometimes other medicines are also used. Talk with your PCP about what kind of treatment is right for you.
*Your primary care provider (PCP) is your main doctor or healthcare provider who helps you stay healthy and handles your care.
