What’s DAO Deficiency

DAO Deficiency is an alteration in the metabolism of exogenous histamine that appears when Diamine Oxidase (DAO) enzyme activity is low. In other words, when for some reason there is a significant deficiency in the functional activity of the main enzyme in the metabolism of histamine.
DAO deficiency is the functional lack of the enzyme Diamine Oxidase or DAO, an enzyme synthetized in the enterocytes and the main responsible for eliminating histamine, a molecule found in food.
