Can High Blood Pressure Cause Migraines?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Yes, high blood pressure can trigger migraines and worsen existing headache disorders. Research shows that people with hypertension are 1.5 times more likely to experience migraines compared to those with normal blood pressure. The connection works both ways - severe migraines can temporarily raise blood pressure during attacks, while chronically elevated blood pressure may trigger headache episodes by affecting blood vessel function in the brain. Blood pressure medications like ACE inhibitors and beta-blockers are sometimes prescribed specifically for migraine prevention. If you experience frequent headaches alongside high blood pressure readings above 140/90 mmHg, discuss this pattern with your healthcare provider for proper evaluation and treatment.
