What should you know about primary hypertension?

Blood pressure changes with activity, stress, sleep, pain, and the setting, so one reading does not establish the diagnosis. Clinicians may repeat measurements at appointments or ask you to monitor at home with a validated device. Over time, untreated hypertension can strain blood vessels and organs, including the heart, brain, and kidneys. It can contribute to Angina, Heart Failure, Chronic Kidney Disease, Stroke, or Transient Ischaemic Attack, although these conditions are not the explanation for every raised reading. Obesity and Obstructive Sleep Apnoea can be relevant health factors.

Keep a record of readings, including when and how they were taken, and bring it to appointments. Take prescribed medicine consistently; do not stop it because you feel well, since hypertension often has no obvious symptoms. Your plan may include reducing salt, staying active within your abilities, avoiding tobacco, moderating alcohol, improving sleep, and addressing weight or other health conditions. Ask how often to check your pressure and what reading should prompt a call. Lifestyle changes support treatment but should not replace prescribed medicine without clinical advice.

Call emergency services for a very high reading accompanied by chest pain, severe breathlessness, new weakness or numbness, difficulty speaking, confusion, fainting, or sudden vision change. Seek prompt medical advice for repeated unusually high readings, severe headache, or symptoms after a medicine change. Do not delay emergency care while repeatedly checking the monitor.

How was my diagnosis confirmed? What target suits my overall health? Which medicines are being considered, and what side effects matter? Could sleep apnoea, kidney disease, or another condition affect my plan?
