Histamine Intolerance

Histamine Intolerance is an intolerance of ingested histamine probably caused by dysfunction of the two metabolizing enzymes HNMT and DAO. The symptoms are similar to allegic reactions.

Pathogenesis

Error occured.
Histamine metabolism

Symptoms

Diarrhea
In patients with histamine intolerance diarrhea manifests after the ingestion of greater amounts of biogenic amines.
