HDL (high-density lipoprotein) cholesterol: This is considered the "good" cholesterol. Levels above 60 mg/dL are considered protective, while levels below 40 mg/dL in men and 50 mg/dL in women are a risk factor for heart disease. The higher the HDL, the better. LDL (low-density lipoprotein) cholesterol: This is the "bad" cholesterol. Optimal levels are below 100 mg/dL. Levels between 100-129 mg/dL are acceptable for people with no health issues but considered borderline high. Levels over 160 mg/dL are considered very high and increase risk of heart disease. The lower the LDL, the better. Total cholesterol: Ideally, this should be below 200 mg/dL. Levels between 200-239 mg/dL are considered borderline high. Over 240 mg/dL is considered high. Triglycerides: Normal triglyceride levels are below 150 mg/dL. Levels over 200 mg/dL are considered high. The optimal lipoprotein profile is having low LDL and triglycerides, with higher protective HDL levels. Lifestyle factors like diet, exercise, weight management and not smoking can help maintain healthier cholesterol and triglyceride values. Consult your doctor about specific target levels for your individual health profile. They may recommend medication if levels are not within a healthy range through lifestyle alone.
