Alcohol flush reaction, also known as Asian flush, Asian glow, or Asian blush, refers to a physiological response characterized by a noticeably flushed or reddened face, neck, and sometimes the entire body, after consuming alcohol. It is more prevalent among individuals of East Asian descent, although it can occur in people from other ethnic backgrounds as well.
The flush reaction occurs due to an inherited deficiency in the enzyme aldehyde dehydrogenase (ALDH), which is responsible for metabolizing alcohol. This deficiency leads to the accumulation of acetaldehyde, a toxic byproduct of alcohol breakdown. Acetaldehyde causes blood vessels to dilate, resulting in the redness, warmth, or flushing of the skin.
In addition to facial flushing, alcohol flush reaction may be accompanied by other uncomfortable symptoms such as nausea, rapid heartbeat, dizziness, headache, and difficulty breathing. People experiencing this reaction may have a lower tolerance for alcohol, which can lead to feeling intoxicated more quickly and experiencing more severe hangovers.
It is important to note that alcohol flush reaction is not a sign of intoxication or allergy but rather a genetic variation in alcohol metabolism. As a result, individuals with the flush reaction may be more prone to certain health risks related to alcohol consumption, including an increased risk of alcohol-associated cancers and liver disease.
To manage the symptoms, individuals with alcohol flush reaction are advised to drink alcohol in moderation or avoid it altogether. They should also be aware of potential interactions with medications and consult a healthcare professional if needed.
