You may feel no symptoms
Pressure can be high without symptoms. Controlling it reduces heart, stroke, and kidney risks.
More details
Most people with high blood pressure have no obvious symptoms, so feeling well does not rule it out. Persistent hypertension raises the risk of heart disease, stroke, and kidney problems. Measuring and treating it when needed can reduce these risks even when everyday life feels normal.
What do the two numbers mean?
The upper number measures pressure during heartbeats, the lower between beats. Your clinician agrees a target using repeated readings and health history.
More details
The upper number is systolic pressure when the heart beats, and the lower number is diastolic pressure between beats. Both matter. Your clinician interprets repeated measurements alongside age and other conditions and agrees a target. Clinic and home readings may use different interpretation thresholds.
Confirming a pattern of high readings
Caffeine, activity, and cuff technique affect readings. Home records or a 24-hour monitor can help confirm the diagnosis.
More details
Activity, caffeine, and cuff technique can affect a reading, and clinic measurements may differ from those at home. Your clinician may therefore request a home record over several days or a monitor worn for 24 hours. This helps confirm hypertension and guide the next steps.
