Alcohol flush reaction
Alcohol flush reaction
Alcohol flush reaction (pronunciation: /ˈælkəhɒl flʌʃ riˈækʃən/), also known as Asian flush syndrome, Asian glow, or Asian blush, is a condition in which a person develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages. The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol.
Etymology
The term "Alcohol flush reaction" directly describes the condition's most prominent symptom, a flush (or blush) on the face and body that occurs after consuming alcohol. The term "Asian flush" is derived from the higher prevalence of this condition in individuals of East Asian descent.
Symptoms
The most noticeable symptom of alcohol flush reaction is the red flush that appears on the skin. Other symptoms can include:
- Nausea
- Dizziness
- Rapid heartbeat (known as tachycardia)
- Headache
Causes
The condition is caused by a deficiency of the enzyme aldehyde dehydrogenase 2 (ALDH2), which is responsible for breaking down acetaldehyde, a toxic metabolite of alcohol. This deficiency is most commonly found in individuals of East Asian descent.
Treatment
There is no cure for alcohol flush reaction, but symptoms can be managed. Avoiding or limiting alcohol consumption is the most effective way to prevent symptoms. Some people also find relief from symptoms by taking antihistamines before consuming alcohol.
