Hyperlipidemia usually doesn’t cause symptoms at first. Most people only find out they have it through a blood test. If cholesterol or triglyceride levels get very high, visible signs may develop—such as yellowish bumps (xanthomas) on the skin or fatty deposits near the eyes. As the condition progresses and arteries become blocked, symptoms of atherosclerosis may appear, including chest pain (angina), heart attack, or stroke.
