HDL, or high-density lipoprotein, is a type of cholesterol found in the blood. Unlike low-density lipoprotein (LDL), which is often referred to as 'bad' cholesterol, HDL plays a protective role in heart health. It helps carry cholesterol away from the arteries and back to the liver, where it can be processed and removed from the body.
HDL is important for health because it helps reduce the risk of heart disease and stroke. Higher levels of HDL cholesterol are associated with a lower risk of these conditions, as it helps to prevent the buildup of plaque in the arteries. This plaque can restrict blood flow and lead to serious cardiovascular problems.
In the body, HDL functions by picking up excess cholesterol from the cells and other tissues, transporting it to the liver for disposal. This process helps maintain a healthy balance of cholesterol levels and supports overall cardiovascular health. By removing harmful cholesterol from the bloodstream, HDL contributes to better heart function and reduces the risk of atherosclerosis, a condition characterized by the hardening of arteries.
Maintaining healthy HDL levels is essential for good health. Regular check-ups with a healthcare provider can help monitor cholesterol levels and ensure they are within a healthy range.
