Doctors urged to tell patients Asian glow signals health risk, not harmless quirk

Brian Zhang, a second-year medical student at Stanford and student body president, wrote an opinion piece urging doctors to discuss the so-called "Asian glow" with patients.

The facial flushing that many East Asian individuals experience after a few drinks is not a harmless quirk. It reflects reduced activity of the mitochondrial aldehyde dehydrogenase enzyme, which impairs the body's ability to metabolize acetaldehyde, a toxic by-product of alcohol.

Some people try to mask the reaction by taking over-the-counter antihistamines such as famotidine, but this does not eliminate the underlying metabolic risk and may give a false sense of tolerance.

Zhang argues that clinicians should educate patients about the potential health implications, including increased cancer risk, and advise moderation or avoidance of alcohol rather than simply ignoring the flush.
