Reasons for Hypertension

Many people have primary hypertension, where several influences gradually raise pressure without one single cause. Narrowed or stiffened blood vessels, altered kidney salt handling, and hormonal regulation can contribute. Secondary hypertension has an identifiable driver, such as chronic kidney disease, obstructive sleep apnoea, or a medicine. High blood pressure may have no noticeable symptoms, so a reading needs confirmation using appropriate repeated measurements rather than symptoms alone.

Repeat the measurement when seated and rested, using a correctly sized cuff, and record the results with the time and any symptoms. Review salt intake, activity, sleep, alcohol, smoking, and medicines with a clinician. Do not change prescribed tablets on your own. Assessment may include blood and urine tests, a medication review, and checks for kidney or cardiovascular effects.

Seek emergency help for a high reading accompanied by chest pain, severe breathlessness, new weakness, trouble speaking, confusion, or sudden vision loss. Arrange medical review for repeatedly elevated readings, headaches with neurological symptoms, pregnancy-related concerns, or missed treatment doses.

Could another condition or medicine be raising my pressure? How should I measure it at home? What target and follow-up plan apply to me? Which symptoms need emergency help?
