Direct answer: Dehydration headache and migraine can overlap, but migraine usually includes additional features like sensory sensitivity, nausea, or stronger disability. Structured logging helps separate patterns over time.
Key Takeaways
- Hydration is a modifiable factor, not the only migraine cause.
- Track intake timing plus headache timing.
- Look for repeated co-occurrence before concluding causality.
- Use monthly reports to discuss findings with your clinician.
