High cholesterol levels in the blood (hypercholesterolemia) can lead to atherosclerosis (deposits of plaque in the blood vessels) and vascular diseases. Maintaining appropriate levels of "good" cholesterol ("high density lipoprotein, or HDL) and "bad" cholesterol (low density lipoprotein, or LDL) in the blood is crucial for vascular health. While genetics can play a part in cholesterol levels, levels of cholesterol in the blood can be improved by diet changes, regular exercise and in some cases by taking cholesterol lowering medications. If your cholesterol level puts you at risk for vascular diseases here are two programs that may be of help:
