High cholesterol, also known as hyperlipidemia, refers to high levels of cholesterol in your blood. Total cholesterol is the collection of different kinds of lipids found in the cells of your body.
Cholesterol is essential for building cell membranes, producing hormones, and aiding in the digestion of fats. However, when cholesterol levels become too high, it can lead to the buildup of plaque in the walls of your arteries. Plaque buildup can narrow the arteries and restrict blood flow to the heart, brain, and other parts of the body.
This can lead to various health problems and increase the risk of cardiovascular disease and stroke.
