The alcohol flush response, generally known as Asian Flush, is a situation characterised by facial redness after consuming alcohol. This response primarily stems from a genetic deficiency in aldehyde dehydrogenase 2 (ALDH2), an enzyme essential for metabolizing acetaldehyde, a poisonous byproduct of alcohol breakdown. When ALDH2 is poor, acetaldehyde accumulates within the physique, resulting in vasodilation and the attribute flushing, in addition to different signs like nausea, headache, and elevated coronary heart charge.
Whereas the genetic variant liable for ALDH2 deficiency is most prevalent in East Asian populations, it’s not unique to them. The presence of this genetic mutation, no matter ethnicity, dictates whether or not a person experiences the alcohol flush response. Its significance lies in understanding particular person alcohol tolerance and related long-term well being dangers. Research have indicated that people with ALDH2 deficiency could face an elevated danger of esophageal most cancers with continued alcohol consumption.
