Diamine oxidase or DAO is an enzyme naturally present in the gut. Its main function is to metabolise the histamine we ingest from many of the foods we eat.
DAO Deficiency occurs when this enzyme is less active. This means that the histamine is not metabolised properly so it is absorbed through the intestinal lining (epithelium) and accumulates in the blood. This, in turn, can trigger various symptoms which can be severe and pharmacologically hard to treat such as: migraine, fibromyalgia, atopic skin, digestive problems and ADHD.
