Tag: Alcohol flush reaction

An estimated 540 million people worldwide experience a genetic intolerance to alcohol, a phenomenon that can cause immediate, unpleasant reactions. For many, this is the underlying reason behind the perplexing question: Why do I feel awful after one beer? Understanding your body's unique response to alcohol and its ingredients is crucial for your health.

Approximately 30-50% of East Asians, including many Koreans, experience a phenomenon known as “Asian flush” after drinking alcohol. This common genetic trait is often casually referred to as the Korean alcohol syndrome, and it involves a noticeable flush or reddening of the face, neck, and shoulders. More than just a cosmetic effect, this syndrome is a physiological response with important health implications.
