Can high blood pressure cause headaches?
The relationship between blood pressure and headache is more nuanced than many people think.

The short answer
Mild to moderate hypertension is usually silent. Severe hypertension (≥180/120) can cause headaches, especially in the morning, and may signal a hypertensive emergency if accompanied by visual or neurological symptoms.
When to seek care
A severe headache with very high blood pressure and visual change, confusion, or chest pain is an emergency.
Key takeaways
- ✓ Most everyday headaches are not caused by blood pressure.
- ✓ BP ≥180/120 with symptoms = emergency.
- ✓ Routine BP checks are important even without symptoms.
When to seek care
- • BP ≥180/120 with any new symptom
- • New severe morning headaches with known hypertension

FAQs
Should I take my blood pressure when I have a headache?
It's reasonable. But occasional high readings during pain are not the same as sustained hypertension.
