Calculate cardiovascular health risk based on cholesterol levels.
Understanding cholesterol levels and cardiovascular health. Cholesterol essential for cell membranes, hormone production, vitamin synthesis—but excess in blood increases cardiovascular disease risk. Total cholesterol below 200 mg/dL desirable; 200-239 borderline; 240+ high risk. LDL cholesterol ("bad") deposits in arteries: below 100 optimal, 100-129 near optimal, 130-159 borderline, 160-189 high, 190+ very high.
HDL cholesterol ("good") removes excess cholesterol: 60+ mg/dL protective, 40-59 normal, below 40 low risk. Triglycerides (blood fat): below 150 normal, 150-199 borderline, 200-499 high, 500+ very high. Cardiovascular disease risk increases with high LDL, low HDL, high triglycerides. Causes include genetics (familial hypercholesterolemia), diet (saturated fats, trans fats, cholesterol), obesity, sedentary lifestyle, smoking.
Prevention and management: aerobic exercise (150 minutes weekly), diet (Mediterranean diet emphasizes olive oil, fish, vegetables), weight loss, smoking cessation, medication (statins) if needed. Nutrition factors: dietary fiber reduces cholesterol absorption; omega-3 fatty acids (fish) lower triglycerides; plant sterols block cholesterol absorption. Medication decisions involve discussion with healthcare providers—statin benefits/risks vary individually. Regular testing (every 5 years if normal, annually if elevated) monitors trends and treatment effectiveness. Understanding cholesterol profiles enables informed lifestyle changes and medical decisions supporting cardiovascular health..
