Why it matters

High blood pressure usually has no symptoms while it damages blood vessels and organs, and WHO estimates that 44% of adults who have it are unaware. Screening opens the door to effective treatment, but a measurement alone does not reduce risk. The USPSTF recommends yearly checks from age 40 or earlier when risk is higher, with readings outside the clinic to confirm a diagnosis.

How to do it

  1. Arrange a blood pressure check and keep a copy of the result; in England the NHS Health Check covers ages 40 to 74 every 5 years.
  2. Use a validated upper arm device and sit quietly for 5 minutes before measurement.
  3. If a clinic reading is high, ask about home or ambulatory monitoring to confirm it.
  4. Agree on follow-up and treatment with your clinician if pressure stays high.

A clinician should confirm persistent high readings and set treatment targets. Pregnancy needs its own blood pressure care plan.

Do it

Pick the time you have. Anything beats nothing.

Start with the time you have

1 minute

Recall when your blood pressure was last checked and the numbers; if you don't know, that is your cue to book a check.

In real life

  • Ask your pharmacy whether it offers blood pressure checks and what they cost.
  • Bring your last blood pressure result to your next appointment, even if you feel well.

Watch out for

  • Common mistakeFeeling well does not rule out high blood pressure, so arrange a check instead of waiting for symptoms.
  • Common mistakeOne high reading is not a diagnosis, so ask how it should be confirmed.
