HDL cholesterol: How to boost your 'good' cholesterol
Low-density lipoprotein cholesterol. High levels of low-density lipoprotein (LDL) can eventually build up within the walls of your blood vessels and narrow the passageways. Sometimes a clot can form and get stuck in the narrowed space, causing a heart attack or stroke. This is why LDL cholesterol is often referred to as "bad" cholesterol.
