High cholesterol levels can lead to significant detrimental effects on cardiovascular health. Elevated low-density lipoprotein (LDL) cholesterol can result in the formation of plaque in the arteries, narrowing them and increasing the risk of atherosclerosis. This condition can lead to heart disease, hypertension, and stroke. Conversely, high-density lipoprotein (HDL), the "good" cholesterol, helps remove LDL from arteries, but insufficient levels can exacerbate health risks. Regular monitoring of cholesterol levels and lifestyle modifications, such as a heart-healthy diet and exercise, are crucial in managing cholesterol and promoting cardiovascular well-being.
