Cholesterol is essential but can raise heart disease risk when levels are high. Understand LDL, HDL and triglycerides, common total-cholesterol categories, major risk factors, and practical steps to lower risk.
High cholesterol usually causes no symptoms - it is detected by blood tests. Complications include angina or heart attack, stroke (FAST), and peripheral artery disease; lifestyle changes and medications can lower risk.
High cholesterol usually causes no obvious symptoms. Visible signs like xanthomas or corneal arcus appear mainly when levels are very high. Screening with a lipid panel and managing risk factors can help prevent heart attack and stroke.
Cholesterol testing detects elevated LDL and other lipid issues before symptoms, allowing lifestyle changes or medications to reduce heart attack and stroke risk. Start screening in early adulthood, repeat periodically, and follow clinician guidance on treatment.
Cholesterol-lowering medicines - from statins to newer injectables - reduce heart attack and stroke risk. Choice depends on individual risk, tolerance, and goals; adherence and lifestyle remain essential.
