How to Use the Low Blood Pressure Checker
Low blood pressure is generally defined as a systolic reading under 90 mmHg or a diastolic reading under 60 mmHg, but the accompanying symptoms — dizziness, fainting, fatigue — often matter more than the numbers alone. This checker combines your readings with orthostatic dizziness, fainting history, and chronic fatigue to estimate your symptom risk level.
Orthostatic hypotension, where you feel dizzy or your vision blacks out when standing up quickly from sitting or lying down, is especially common in young women and people with a slim build. Standing up slowly and getting enough water and salt can ease these symptoms. If you've actually fainted, though, the cause could be a cardiovascular issue rather than simple low blood pressure, so it deserves closer attention.
Check the FAQ below for the blood pressure thresholds and coping tips. This result is not a medical diagnosis — if fainting or dizziness keeps happening, please see an internist or cardiologist.
