LDL HDL risk estimator
For adults aged 20 to 29, average cholesterol levels remain relatively low compared to older age groups. Total cholesterol often ranges between 160 and 200 mg/dL, while LDL usually falls around 90–120 mg/dL. HDL typically measures 45–55 mg/dL, offering natural protection. Triglycerides are generally under 150 mg/dL. At this stage, overall cardiovascular risk is usually low, especially for non-smokers with normal blood pressure.
In the 30s, total cholesterol and LDL begin to rise slightly. Many adults see total cholesterol around 180–210 mg/dL and LDL near 110–130 mg/dL. HDL remains fairly stable, typically 45–55 mg/dL. Triglycerides may reach 100–160 mg/dL. Systolic blood pressure shows a slight increase for some, particularly those with sedentary lifestyles. Combined lifestyle factors can push risk levels from low to moderate during this decade.
During the 40s, total cholesterol often measures 190–220 mg/dL, with LDL averaging 120–150 mg/dL. HDL may slightly decrease, moving closer to 45 mg/dL in some adults. Triglycerides commonly reach 120–180 mg/dL. Blood pressure gradually rises, with systolic readings often between 120–135 mmHg. Adults who smoke or have other metabolic conditions may experience higher cardiovascular risk during this stage.
In the 50s, total cholesterol frequently measures 200–240 mg/dL, while LDL rises to 130–160 mg/dL. HDL tends to decline slightly, averaging 40–50 mg/dL. Triglycerides commonly reach 140–200 mg/dL. Systolic blood pressure may range 130–145 mmHg. Lifestyle habits and family history strongly influence overall risk, often moving moderate levels into high-risk categories for some adults.
For those aged 60 and above, total cholesterol often falls between 210–250 mg/dL, and LDL typically measures 140–170 mg/dL. HDL averages around 40–50 mg/dL, while triglycerides reach 150–220 mg/dL. Systolic blood pressure may climb to 140–160 mmHg in many adults. Aging combined with lifestyle factors can elevate overall cardiovascular risk, making regular monitoring and adjustments critical for maintaining stable levels.
