The short explanation
Both readings can be real. Many people have higher blood pressure in a clinic or camp setting because of rushing, talking, anxiety or a badly sized cuff. This is sometimes called white-coat high blood pressure. Home readings, taken properly, often give a truer picture of your everyday pressure. The safest next step is to collect a set of careful home readings over several days, morning and evening, and show them to a doctor. Your doctor may also suggest a 24-hour BP monitor, which records readings through a normal day.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Home machines vary. An upper-arm automatic machine that has been checked against a clinic reading is more reliable than a wrist machine.
- Sit quietly for a few minutes, feet flat, back supported, arm resting at heart level, and avoid tea, coffee and exercise just before measuring.
- Even white-coat high readings are worth following up, because some people later develop sustained high blood pressure, especially with a family history, weight gain or diabetes.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot say whether your blood pressure is truly high. That needs repeated reliable readings reviewed by a clinician.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How many home readings should I record, and when?
- Is my home machine accurate compared with yours?
- Would a 24-hour BP monitor help?
- How often should I recheck if my home readings stay normal?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 if a very high reading comes with chest pain, severe headache, sudden weakness, confusion, blurred vision or trouble speaking.
Book an appointment soon
- See a doctor within a couple of weeks with your home readings to decide whether follow-up or treatment is needed.
Raise it at a routine appointment
- If readings stay normal, recheck your blood pressure at least yearly or as your doctor advises.
