Facial swelling and high blood pressure

High blood pressure often causes no noticeable symptoms. Facial puffiness may occur when another problem affects fluid balance, including chronic kidney disease or heart failure. Some blood-pressure medicines can rarely trigger angioedema, a deeper swelling of the face, lips or tongue. A reading alone cannot explain new swelling. Tell the clinician when it began, which medicines you take, and whether the swelling is one-sided, itchy, painful or worse after waking.

Measure blood pressure using a validated device while seated and rested, and record the reading with the time and any symptoms. Take prescribed medicine as directed; do not double a dose or stop treatment without advice. Arrange a clinical review for persistent or recurring swelling. Assessment may include an examination, medication review, urine testing and blood tests, depending on the findings. Reduce avoidable salt intake if your clinician has recommended this, but do not sharply restrict fluids without guidance.

Seek emergency help for facial swelling with trouble breathing, tongue or throat swelling, chest pain, severe headache, confusion, weakness on one side, trouble speaking, fainting or sudden vision change. These symptoms can occur with a severe allergic reaction, stroke or another urgent condition. Do not drive yourself if you feel seriously unwell.

Ask whether a medicine could be contributing, whether kidney or heart checks are needed, how to monitor blood pressure correctly, and which reading or symptom should trigger urgent care.
