Cholesterol - high; Lipid disorders; Hyperlipoproteinemia; Hyperlipidemia; Dyslipidemia; Hypercholesterolemia
Cholesterol is a fat (also called a lipid) that your body needs to work properly. Too much bad cholesterol can increase your chance of getting heart disease, stroke, and other problems.
The medical term for high blood cholesterol is lipid disorder, hyperlipidemia, or hypercholesterolemia.
There are many types of cholesterol. The ones talked about most are:
Some health conditions can also lead to abnormal cholesterol, including:
Medicines such as certain birth control pills, diuretics (water pills), beta-blockers, and some medicines used to treat depression may also raise cholesterol levels. Several disorders that are passed down through families lead to abnormal cholesterol and triglyceride levels. They include:
Smoking does not cause higher cholesterol levels, but it can reduce your HDL (good) cholesterol.
A cholesterol test is done to diagnose a lipid disorder. Different experts recommend different starting ages for adults.
It is important to work with your health care provider to set your cholesterol goals. Newer guidelines steer doctors away from targeting specific levels of cholesterol. Instead, they recommend different medicines and doses depending on a person's history and risk factor profile. These guidelines change from time to time as more information from research studies becomes available.
General targets are:
If your cholesterol results are abnormal, you may also have other tests such as:
Steps you can take to improve your cholesterol levels and to help prevent heart disease and a heart attack include:
Your provider may want you to take medicine for your cholesterol if lifestyle changes do not work. This will depend on:
You are more likely to need medicine to lower your cholesterol:
Almost everyone else may get health benefits from LDL cholesterol that is lower than 160 to 190 mg/dL.
There are several types of drugs to help lower blood cholesterol levels. The drugs work in different ways. Statins are one kind of drug that lowers cholesterol and has been proven to reduce the chance of heart disease. Other drugs are available if your risk is high and statins do not lower your cholesterol levels enough. These include ezetimibe and PCSK9 inhibitors.
High cholesterol levels can lead to hardening of the arteries, also called atherosclerosis. This occurs when fat, cholesterol, and other substances build up in the walls of arteries and form hard structures called plaques.
Over time, these plaques can block the arteries and cause heart disease, stroke, and other symptoms or problems throughout the body.
Disorders that are passed down through families often lead to higher cholesterol levels that are harder to control.
