What are the risk factors for hypertension?

Blood pressure reflects the force of blood against artery walls. Family tendency and age can affect artery stiffness and how the kidneys regulate salt and fluid. Excess weight, limited activity, a diet high in salt, and regular heavy alcohol use can push pressure higher. Kidney disease can disturb fluid and hormone control, while Obstructive Sleep Apnoea can repeatedly activate the body's stress response during sleep. Some medicines, including certain pain medicines and decongestants, may also raise readings. Many people have more than one contributor, and a single high reading does not confirm Hypertension.

Arrange repeated blood pressure checks rather than relying on one measurement. Use a validated home monitor if your clinician recommends it, and record readings with the time and circumstances. Reduce salty packaged foods, choose more vegetables and pulses, move regularly, work toward a healthy weight, avoid smoking, and review alcohol intake. Ask a pharmacist or clinician whether medicines or supplements could affect your pressure. Treatment of Chronic Kidney Disease, Obesity, or sleep apnoea may be part of the wider plan.

Seek emergency help for very high blood pressure accompanied by chest pain, severe breathlessness, weakness on one side, trouble speaking, confusion, or sudden vision change. Seek prompt clinical advice for repeated high readings, headaches with visual symptoms, or blood pressure concerns during pregnancy. Do not take an extra dose of prescribed medicine unless instructed.

How should I measure my blood pressure at home? Could my medicines, kidneys, weight, or sleep be contributing? Do I need tests for an underlying cause? What reading or symptom should prompt urgent help?
