Blood pressure reflects the force of blood pushing against artery walls. It is usually written as two numbers: systolic pressure and diastolic pressure.
Persistently elevated blood pressure can increase the workload on the heart and blood vessels. Over time, this may contribute to heart, kidney, brain, and vascular complications.
Blood pressure can change during the day because of activity, stress, sleep, caffeine, pain, medications, and measurement technique.
One reading does not always mean a diagnosis. Repeated readings, correct measurement technique, and clinical review are important.
Helpful questions for a clinician include: Are my readings consistently high? Should I monitor at home? What target range is appropriate for me? What lifestyle or medication steps should I consider?
