Must people who blush when drinking not drink?

People who blush when drinking can't drink. The person who blushes after drinking is because the liver lacks an enzyme called acetaldehyde dehydrogenase. Due to the lack of this enzyme, ethanol in the body can not be completely metabolized during metabolism, and there will be symptoms of excessive acetaldehyde storage. Excessive acetaldehyde accumulation can cause facial flushing, palpitation, palpitation, dizziness, headache and fatigue, and in severe cases, it can induce hypotension and lead to shock.
