Metabolic Syndrome Calculator

Metabolic syndrome is a cluster of five risk factors — central obesity (waist circumference), elevated triglycerides, low HDL cholesterol, high blood pressure, and elevated fasting glucose — that together raise the risk of cardiovascular disease and type 2 diabetes more than any one factor alone. It's defined by the 2005 AHA/NHLBI scientific statement, which harmonized the original 2001 NCEP ATP III criteria.

No. This is a screening organizer based on the published ATP III criteria, not a diagnostic test. It relies on the lab values and measurements you enter yourself. A clinician should confirm any flagged criteria with an in-person waist measurement, blood pressure reading, and a current fasting lipid and glucose panel before making a diagnosis.

Meeting 2 criteria is below the diagnostic threshold (which requires 3 or more), but it isn't nothing — each flagged factor independently raises your cardiometabolic risk, and people with 2 criteria often progress to 3 or more over time without lifestyle or medical intervention. It's worth discussing prevention with a healthcare professional rather than waiting for a third criterion to appear.

Yes, for many people. Because the criteria are largely driven by excess weight (especially abdominal fat) and inactivity, sustained weight loss, regular physical activity, and dietary changes can lower blood pressure, triglycerides, and glucose while raising HDL — often moving multiple criteria back under threshold at once. Medication may also be needed for some factors even after lifestyle changes.

The waist circumference cut-points used here (102 cm / 40 in for men, 88 cm / 35 in for women) are the US/AHA values validated primarily in Western populations. The International Diabetes Federation (IDF) recommends lower, ethnicity-specific waist thresholds for South Asian, East Asian, and several other populations, where metabolic risk can appear at a smaller waist size. This calculator is also not intended for children or adolescents, who use separate pediatric definitions.
