Informations about the disease

Clinical Comment

Alcohol intolerance is a genetic metabolic disorder triggered by ethanol consumption. Alcohol intolerance is associated with a combination of certain ADH1B, ALDH2 and possibly ADH1C gene variants that affect the ethanol-neutralizing metabolism. Higher levels of acetaldehyde trigger the below-mentioned symptoms because the above-mentioned enzymes metabolize alcohol inefficiently. The gene variants in question are most commonly detected in people of East Asian descent, in whom alcohol intolerance is a more common problem leading to skin flushing, rashes, nausea and vomiting, diarrhea, low blood pressure, palpitations and drowsiness.
