What is cholesterol?

what is the definition of cholesterol

what is the definition of cholesterol,Cholesterol is a type of fat levels (lipids). Your cells need cholesterol, and your body does everything you need. But you also get the cholesterol from the food you eat.

If you have too much cholesterol builds up in your arteries. (Arteries are the blood vessels that carry blood from the heart.) This is known as the hardening of the arteries, or atherosclerosis camera.gif. It is the starting point of some heart problems and blood circulation. Accumulation can reduce the arteries and make it harder for the blood to flow through them. Accumulation can also lead to dangerous blood clots and inflammation which can cause heart attacks and strokes.

There are different types of cholesterol.

LDL is the "bad" cholesterol. It is the kind that can increase your risk of heart disease, heart attack and stroke.
HDL is the "good" cholesterol. He is the type that is linked to a lower risk of heart disease, heart attack and stroke.

His blood pressure.
If you have diabetes or not.
Age, sex and race.
Whether you smoke or not.
What affects cholesterol?

Many factors can affect cholesterol levels, including:

The food you eat. Eating too much saturated fat, trans fats and cholesterol can increase your cholesterol levels.
Excess weight. This can reduce HDL ("good").
Inactive. No exercise can reduce HDL ("good").
Years. Cholesterol starts to increase after 20 years.
family history. If family members have had or high cholesterol levels, you can have it.

How to test cholesterol?

You need a blood test to check your cholesterol level.

A cholesterol test, also called lipid panel, measures all fat in the blood, including total cholesterol, LDL and HDL.

High levels of cholesterol do not make you feel sick. Thus, the blood test is the only way to know your cholesterol level.

The way you will reduce your risk will depend on how high the risk of heart attack and stroke. It will also depend on how the medication feels. Your doctor can help you know your risk. Your doctor can help balance the benefits and risks of treatment options.

Statin medication can reduce the risk of heart attack and stroke.

For people whose chances of having a heart attack or stroke is high, taking a statin can be helpful.
For others, it is not so clear whether they should take a statin. You and your doctor will examine your overall health and any risk you have of heart attack and stroke.
