Impact of alcohol on aging

The impact of alcohol on aging is multifaceted. Evidence shows that alcoholism or alcohol abuse can cause both accelerated (or premature) aging – in which symptoms of aging appear earlier than normal – and exaggerated aging, in which the symptoms appear at the appropriate time but in a more exaggerated form. The effects of alcohol use disorder on the aging process include hypertension, cardiac dysrhythmia, cancers, gastrointestinal disorders, neurocognitive deficits, bone loss, and emotional disturbances especially depression. Furthermore, chronic ethanol consumption can contribute to premature aging by depleting cellular NAD+, a key coenzyme vital for DNA repair and maintaining cellular health through proteins like sirtuins.
