Symptoms of High Density Lipoprotein
High-density lipoproteins (HDL) are one of the five major groups of lipoproteins. Lipoproteins are complex particles composed of multiple proteins which transport all fat molecules (lipids) around the body within the water outside cells. They are typically composed of 80-100 proteins per particle (organized by one, two or three ApoA; more as the particles enlarge picking up and carrying more fat molecules) and transporting up to hundreds of fat molecules per particle. Unlike the larger lipoprotein particles which deliver fat molecules to cells, HDL particles remove fat molecules from cells which want to export fat molecules. The fats carried include cholesterol, phospholipids, and triglycerides; amounts of each are quite variable.

High cholesterol is a risk factor for other illnesses and by itself does not cause symptoms. Routine screening blood tests may reveal elevate cholesterol levels in the blood. Doctors suggest that everyone aged 20 years and older should have their blood cholesterol level measured at least once every 5 years. It is best to have a blood test called a lipoprotein profile to find out your cholesterol numbers.
