What should you know about malignant hypertension symptoms?

Malignant hypertension may present with a severe headache, blurred or reduced vision, confusion, unusual drowsiness, nausea or vomiting. Chest pain or breathlessness may indicate strain on the heart or fluid in the lungs. Weakness, numbness, facial drooping or difficulty speaking may indicate Stroke; a brief episode can still need urgent review because it may be a Transient Ischaemic Attack. Symptoms do not reliably show how much organ injury has occurred.

Stop exertion and arrange emergency medical help. Keep a list of medicines and recent blood-pressure readings available, but do not delay care to keep checking at home. Do not take an unprescribed extra dose or use someone else’s medicine. Tell the team about missed treatment, pregnancy, kidney disease and any recent cold remedies, supplements or recreational drugs.

Call emergency services immediately for new neurological symptoms, severe or sudden headache, loss of vision, chest pain, severe breathlessness, fainting, seizure or marked confusion. These are red flags for possible injury to the brain, heart, eyes or kidneys. Even without these warning signs, a clinician should assess a markedly high reading, especially when symptoms are present.

Ask which symptoms matter most for you, whether your eyes, kidneys or heart need testing, and how to measure blood pressure correctly. Clarify what to do if a reading is high again and whether any current medicine could be contributing.
