Cholesterol levels are intricately linked to heart health. High levels of low-density lipoprotein (LDL) cholesterol can lead to plaque build-up in arteries, increasing the risk of heart disease and stroke. Conversely, high-density lipoprotein (HDL) cholesterol is considered protective, helping to remove LDL from the bloodstream. It's essential to maintain a healthy balance between these types of cholesterol. Regular monitoring through blood tests, along with a healthy diet and exercise, is crucial for managing cholesterol levels and supporting cardiovascular health.
