Histamine levels and migraine frequency are positively correlated.

the evidence backs this
Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that histamine levels and migraine frequency are positively correlated?

Yes. Evidence from clinical and observational studies indicates that histamine levels are elevated in migraine sufferers and that interventions targeting histamine metabolism can reduce migraine symptoms (Izquierdo-Domínguez et al., 2018; Öztürk et al., 2003).

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

Multiple studies (e.g., Sicuteri et al., 1982; Öztürk et al., 2003) show elevated histamine levels in migraine patients, and clinical trials involving DAO supplementation (Izquierdo-Domínguez et al., 2018) demonstrate that managing histamine improves migraine outcomes. No papers refute the core claim.
