Home blood-pressure readings
Home readings can help you and your GP understand your blood pressure over time. Learn how to take a useful reading, keep a record and recognise when you need faster care.
Can a HerDoc GP review my home blood-pressure readings?
Yes. A HerDoc GP can review your home blood-pressure readings, discuss your medicines and help plan ongoing care. The GP considers the pattern alongside your symptoms and health history, and can arrange tests or referrals when needed. Some concerns need confirmed local measurements or an examination.

Why might a GP ask for home readings?
Home monitoring can help investigate a raised clinic reading or review how an existing care plan is working. Blood pressure sometimes rises in a clinic because you feel anxious there. Readings taken in familiar surroundings can add a different view.
High blood pressure, also called hypertension, often has no symptoms. Over time it can affect the heart, brain and kidneys. Feeling well does not tell you whether your blood pressure needs attention.
The top number records pressure when your heart contracts; the bottom number records pressure between beats. Keep both numbers. A single reading cannot establish the whole picture, and a normal home result does not rule out serious illness when you have concerning symptoms.
How can you take a useful home reading?
Use a validated automatic upper-arm monitor with a cuff that fits your arm. Validated means the model has been tested for accuracy. Follow the device instructions; a pharmacist or local clinician can help check the cuff and your technique.
For planned monitoring, follow these steps. If you have severe symptoms, seek help rather than delaying care to take another reading.
- Choose a quiet, comfortable time. Avoid smoking and caffeine for at least 30 minutes beforehand, and avoid measuring straight after exercise. Empty your bladder.
- Sit quietly for five minutes. Support your back, keep your feet flat on the floor and leave your legs uncrossed.
- Place the cuff on your bare upper arm. Support the arm so the cuff is at heart level, following the monitor instructions.
- Keep still and avoid talking or distractions while the monitor measures.
- Take two readings one minute apart and record both, rather than selecting the lower result.
Choose a consistent routine
Agree with your GP when and for how long to measure, including how readings should fit around meals and your usual medicine times. For planned checks, aim for a consistent routine before meals. Do not delay or skip medicine to obtain a reading. Note anything unusual such as pain, stress or recent activity.
HerDoc does not supply, connect to or calibrate monitors. If readings seem unreliable or the cuff does not fit, arrange a local check rather than relying on the numbers.
What should you keep with your readings?
A paper diary or a simple digital record is enough. Keep all readings from the agreed monitoring period, including unexpected ones. Useful details are:
- Both numbers, the date and time, and which arm you used.
- Any symptoms and when they started, even if the reading looked usual.
- Current medicines and directions, recent changes, missed doses and possible side effects.
- Recent exercise, caffeine, smoking, illness, pain or stress that might affect the result.
- Why you started monitoring, earlier clinic readings and any instructions from your usual GP.
Share what you already have
You can upload an image or PDF of your record during HerDoc intake. Have your medicine list and any relevant earlier results available for the phone appointment. You do not need a perfect diary before seeking advice.
What can a HerDoc GP help with?
A HerDoc GP can explain your pattern of readings, review symptoms and medicines, and recommend next steps. The discussion can include side effects, difficulties following the current plan and changes that might affect blood pressure.
Blood pressure varies with activity, stress, illness and measurement technique. The GP considers these factors alongside your health history and risk of heart and blood-vessel disease. Readings across several days can be more useful than repeatedly checking one unexpected result.
When examination or testing may help
A phone consultation cannot provide a physical examination or independently confirm your monitor’s readings. Your GP may recommend a local blood-pressure check, examination or a monitor worn through the day and night when more information is needed.
Depending on the question, blood or urine tests can help assess kidney health or other relevant factors, and an ECG can check the heart’s electrical activity. HerDoc GPs can arrange pathology and referrals after assessment. Not everyone needs these investigations, and local availability and follow-up need to be considered.
Reviewing treatment and follow-up
A plan may include monitoring, a discussion of existing medicines and practical support with activity, food choices, salt, alcohol or smoking. The GP can help identify changes that fit your health and circumstances. Do not stop or change a medicine based on a home reading without individual advice.
Agree when to review the readings, what changes should prompt earlier contact and who will follow up any tests. You can rebook the same HerDoc GP when available or another GP. Later consultations, including results reviews, are separately booked and paid.
When do readings or symptoms need faster care?
A high reading alone does not always mean an emergency. Symptoms, the size of the change and your existing care plan matter. Severe symptoms need action even if a home reading looks normal.
Call 000 for emergency symptoms
Do not wait for another reading or a routine phone appointment if you have:
- Chest pain, severe difficulty breathing, collapse or a seizure.
- Sudden weakness or numbness on one side, a drooping face, trouble speaking or new confusion. Call even if these symptoms pass.
- A sudden severe headache, or a headache with vision changes, confusion or vomiting.
Very high readings with new symptoms
A very high reading with a severe headache, new vision problems, shortness of breath, weakness or feeling seriously unwell needs immediate hospital assessment. Call 000 for severe or sudden symptoms or if you cannot get there safely. Do not keep rechecking to see whether the number falls.
An unexpected reading when you feel well
Unless your clinician has given different instructions, rest quietly and check the cuff and position before repeating an unexpected reading. If it remains much higher than usual, seek medical advice today from a local GP or urgent-care service. Feeling well does not make a very high reading safe to ignore.
If you are measuring for the first time or have no agreed range, share the actual repeated numbers with a clinician for interpretation. If you are concerned or unsure how urgently to act, seek advice today. A monitor’s colour band or warning symbol cannot decide this for you. Ask what range and changes should prompt contact in your circumstances.
For readings that remain above the range agreed with your GP without an abrupt change or symptoms, arrange a review and follow your existing plan. A series of high readings deserves attention, but does not mean everyone needs hospital care.
If you cannot reach a clinician and need help deciding where to go, call Healthdirect on 1800 022 222. Use 000 for an emergency.
During pregnancy
During pregnancy, contact your maternity team or hospital immediately for concerning readings, a severe or persistent headache, blurred vision, upper abdominal pain or sudden swelling of the face or hands. Use 000 for emergency symptoms. A home reading cannot exclude a pregnancy complication.
If you feel dizzy or faint
If you feel dizzy or faint, sit or lie somewhere safe. Seek prompt local assessment if this persists, recurs or follows a medicine change. Use the emergency actions above for collapse, chest pain, confusion or severe breathing difficulty.
FAQs
How many readings should I have ready for the appointment?
Bring whatever reliable readings you already have; do not delay the appointment to create a perfect record. If a clinician has given you a monitoring schedule, follow it. Otherwise, the GP can discuss what pattern would be useful for your circumstances.
What if I do not have a home monitor?
A local GP, nurse or pharmacist can measure your blood pressure. Ask whether home monitoring would help before obtaining a device. A HerDoc appointment can discuss existing readings and next steps, but cannot take a blood-pressure measurement by phone.
Can HerDoc share the consultation or readings with my regular GP?
Yes. Ask the doctor during your appointment if you want a consultation summary or relevant records sent to your regular GP. The doctor can arrange this.
