How to track your blood pressure at home
One reading at the clinic says little about a normal day. Readings at home, taken the same way each time, show your doctor the pattern. The habit is simple. Its value comes from doing it the same way and writing everything down.
A measuring routine, then blood pressure apps. An app logs readings; it does not diagnose. Your doctor decides what your readings mean and what targets apply to you. If you have a very high reading with symptoms such as chest pain, severe headache, weakness or trouble speaking, call emergency services.
Get a cuff that fits
Ask your doctor or pharmacist which home monitors are validated, and choose a cuff size that matches your upper arm. A cuff that is too small or too large can skew results.
Measure the same way every time
Avoid coffee, smoking and exercise just before. Sit with your back supported, feet flat and arm resting at heart height, rest a few minutes and stay quiet during the reading. Follow the routine your doctor gives you.
Log every reading
Write down every result, not only the good ones, with the time and anything unusual such as stress or a missed dose. If you take medicines, see how to manage medications for a family member and medication apps.
Bring it to the appointment
Export or print the log and take it with you. To make the visit count, see how to prepare for a doctor appointment; compare apps in blood pressure apps.
