📐 Formula

Orthostatic Hypotension: Systolic drop ≥20 mmHg OR Diastolic drop ≥10 mmHg within 3 minutes of standing

💡 Practical Example

Sitting: 130/85 | Standing: 108/74. Systolic drop = 22 mmHg. Diastolic drop = 11 mmHg. → Orthostatic Hypotension detected. Consult doctor.

💡 Expert Health Guidance & Clinical Context

  • This calculator uses clinically validated formulas and population reference data published by the WHO and NIH. Results are screening estimates, not medical diagnoses.
  • Consult a licensed healthcare provider before making any changes to diet, medication, or exercise based on these results — individual variation is significant.
  • Genetics, chronic conditions, and concurrent medications can dramatically affect what a "normal" result means for a specific individual.
  • Track your results over time: a single data point is less meaningful than a trend measured consistently across multiple weeks or months.
  • The CDC recommends adults receive routine health screenings at least annually. Use these calculations to prepare informed questions for your physician.
  • Body composition, lifestyle factors, and stress levels all interact with the metrics shown here. No single number captures your full health picture.
  • For pediatric or geriatric populations, reference ranges may differ significantly from the adult standards used in general calculators.
  • Always cross-reference results with laboratory tests, clinical examinations, and professional medical evaluation before acting on any finding.
