What does my blood pressure reading mean?

Enter a recent reading to see the general category it falls into. One reading never tells the whole story — blood pressure changes through the day, and doctors look at repeated readings over time.

Try it with your numbers

Educational only — this does not diagnose high blood pressure. If your reading is very high and you feel unwell, seek urgent care.

Categories follow the widely used American Heart Association ranges for adults.

Health calculators

Six simple tools to help you understand your numbers — BMI, HbA1c, daily calories, unit conversions, walking, and a blood sugar reading. Nothing you enter is sent or saved anywhere; the maths happens in your own browser.

BMI calculator

Body Mass Index from your height and weight — a rough population guide, not a measure of your personal health.

When should you seek care?

A simple way to think about it. When in doubt, it is always safer to ask a clinician than to wait and worry.

🚨 Get emergency help now

  • Chest pain or pressure, or pain spreading to arm, jaw or back
  • Face drooping, arm weakness, or speech difficulty (possible stroke)
  • Severe breathlessness, or lips turning blue
  • Sudden worst-ever headache, fainting, or confusion
  • Heavy bleeding that will not stop
  • Signs of a severe allergic reaction — swelling of lips/tongue, trouble breathing

See a doctor soon

  • Fever lasting more than 3 days, or returning after improving
  • Unexplained weight loss, or a new lump
  • A cough lasting more than 3 weeks
  • Blood in urine, stool, or vomit
  • A mole or skin spot that is changing
  • Low mood, anxiety or poor sleep lasting more than 2 weeks
  • Any symptom that keeps getting worse instead of better

Often safe to self-care

  • A common cold — rest, fluids, and time (usually 7–10 days)
  • Mild muscle aches after new exercise
  • Occasional tension headache that eases with rest and fluids
  • Mild stomach upset for a day or two, if you can keep fluids down
  • Small cuts and grazes — clean, cover, watch for infection

Self-care does not mean ignoring it: if it does not improve, or you feel worse, move up a column.

Six small habits that do a lot of work

Most long-term health is built here — not in big overhauls, but in ordinary days repeated.

  • ✓Walk after meals. Even 10 minutes helps blood sugar and digestion.
  • ✓Half your plate vegetables. The simplest eating rule that actually sticks.
  • ✓Know your numbers. Blood pressure, blood sugar and cholesterol — checked, not guessed.
  • ✓Sleep at a regular time. Same wake time, most days, anchors everything else.
  • ✓Don't smoke; limit alcohol. Still the two biggest levers most people control.
  • ✓Keep vaccinations & screening up to date. Prevention is quieter — and cheaper — than treatment.

Questions patients ask

Can this site tell me what's wrong with me?

No — and be careful of any site that promises that. These guides help you understand conditions, tests and treatments in general, so you can have a better conversation with your own doctor. A diagnosis needs your history, an examination, and often tests.

How often is new content added?

New guides are added as they are written and clinically reviewed — the planned topics are listed on this page. Existing guides are reviewed and updated when guidance changes, and each guide lists its review date at the top.

Where does the information come from?

Guides are written by Dr Syed Ali Turab (MBBS, Diploma in Family Medicine, Certificate in Mental Health) and based on widely used clinical guidance and patient resources from organisations such as the World Health Organization (WHO), the NHS, the US Centers for Disease Control and Prevention (CDC), and the American Heart Association. They are simplified for patients — your clinician can explain how they apply to you.

Should I change my medication based on a guide?

Never stop, start, or change the dose of a prescribed medicine based on something you read online — including here. If a guide raises a question about your treatment, write it down and discuss it with your prescriber.

What should I do in an emergency?

Call your local emergency number or go to your nearest emergency department. Do not wait for a website, message, or appointment if you have chest pain, signs of stroke, severe breathlessness, heavy bleeding, or a severe allergic reaction.
