Alcohol intolerance is an inherited metabolic disorder. Metabolic disorders affect your metabolism, the way your body converts and uses energy. An inherited metabolic disorder means you got this condition from your parents — they each passed down a mutated changed gene that resulted in this disorder.

Alcohol flush reaction is a condition in which a person develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages. The reaction is the result of an accumulation of acetaldehyde , a metabolic byproduct of the catabolic metabolism of alcohol , and is caused by an aldehyde dehydrogenase 2 deficiency. This syndrome has been associated with lower than average rates of alcoholism, possibly due to its association with adverse effects after drinking alcohol.
