ADH1B encodes alcohol dehydrogenase, which metabolizes ethanol to acetaldehyde. Carriers of the fast variant (ADH1B*2, rs1229984) have higher enzyme activity, leading to rapid acetaldehyde buildup – this can cause flushing, nausea, and headache, but fatigue is not a typical symptom. Slow metabolizers (ADH1B*1) may retain alcohol longer, potentially increasing sedation and tiredness after drinking. However, no robust studies directly associate ADH1B with general fatigue independent of alcohol.

Some research suggests this variant may influence stress-induced drinking behavior, as fast metabolizers may experience less reinforcement from alcohol.

Most data come from genetic association and epidemiological studies, not from randomized controlled trials. Therefore, the predictive value for individual stress management is limited.
