Cholesterol is a type of fat found in your blood that is essential for building cells and producing certain hormones. It is produced by your liver and can also be found in some foods you eat.
Cholesterol matters for health because having too much of it in your blood can increase your risk of heart disease. It can build up in your blood vessels, making it harder for blood to flow through your arteries, which may lead to heart attacks or strokes.
In the body, cholesterol plays a crucial role by helping to form the structure of cell membranes. It is also important for producing vitamin D and some hormones, like estrogen and testosterone.
If you have concerns about cholesterol levels, especially if you have a family history of heart disease, it's a good idea to talk to a healthcare provider to learn more.
