  Alcohol intolerance is an inherited metabolic disorder. 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. […] A genetic metabolic disorder causes alcohol intolerance. When most people ingest alcohol, which contains ethanol: An enzyme called alcohol dehydrogenase (ADH) helps metabolize (process) the ethanol. Your liver converts the ethanol to acetaldehyde, a substance that can cause cell damage. Another enzyme called aldehyde dehydrogenase 2 (ALDH2) helps convert acetaldehyde to acetic acid (vinegar), which is nontoxic. In people with alcohol intolerance, a genetic mutation (change) makes ALDH2 less active or inactive. As a result, your body can’t convert acetaldehyde to acetic acid. Acetaldehyde starts to build up in your blood and tissues, causing symptoms.
