Questions
What are the blood pressure categories?
Under the ACC/AHA guideline (2017, kept in the 2025 update): Normal is below 120/80 mmHg; Elevated is 120–129 systolic with diastolic below 80; Stage 1 hypertension is 130–139 systolic or 80–89 diastolic; Stage 2 is 140 or more systolic or 90 or more diastolic. A reading above 180/120 is severe and needs prompt medical attention.
Which number decides my category?
Whichever is higher. If your systolic is in one category and diastolic in another, the higher category applies — for example 125/85 is Stage 1.
Is this a diagnosis?
No. A single reading can be high because of stress, caffeine, a full bladder or talking. Diagnosis needs several readings, ideally including home or ambulatory monitoring. If your reading is above 180/120, or you have chest pain, breathlessness, weakness or vision problems, seek emergency care immediately.
