Cholesterol is a waxy substance found in the blood and all parts of the body. It is made by the liver and is also found in foods from animal sources, such as meat, poultry, fish, eggs, and dairy products.
Cholesterol is important for the body. It helps to build cell membranes, produce hormones, and absorb vitamins. However, too much cholesterol can build up in the blood and increase the risk of heart disease and stroke.
There are two types of cholesterol: LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL cholesterol is often called “bad” cholesterol because it can build up in the arteries and increase the risk of heart disease. HDL cholesterol is often called “good” cholesterol because it helps to remove LDL cholesterol from the blood.
There are several things you can do to lower your cholesterol levels, including:
- Eating a healthy diet
- Exercising regularly
- Maintaining a healthy weight
- Not smoking
- Taking cholesterol-lowering medications, if necessary
If you have high cholesterol, it is important to talk to your doctor about how to lower your levels and reduce your risk of heart disease and stroke.
