What does it mean if I have low HDL cholesterol?

Heart disease risk. Hdl (high density lipoprotein) protects the body by removing excess cholesterol from the walls of arteries. A high HDL (>60 mg/dl) can protect the body from heart disease. A low HDL (<30 mg/dl), on the other hand, is a risk factor for developing heart disease. A patient with low HDL can exercise, lose weight, or take medication to raise it.
Lipoprotein Problems. Cardiovascular (cvd) risk is significantly elevated by an increased number of LDL particles (ldl-p) and a decreased number of HDL particles (hdl-p). Because cholesterol in LDL and HDL particles is highly variable, measures of LDL and HDL cholesterol (ldl-c, hdl-c) often differ from measures of ldl-p and hdl-p. Both high ldl-p and low hdl-p are commonly present when hdl-c is low.
Higher risk. High density lipoprotein, or hdl, is the "good" cholesterol (think "h" for "healthy)." imagine HDL is a vacuum cleaner, sucking up bad cholesterol and lowering your risk of coronary artery blockages and heart attacks. The higher your HDL the better. You can raise your HDL by exercising, eating right, controlling your weight, and not smoking. Rarely, medications are used.
