Health Risks of Alcohol & Facial Flushing

When drinking, alcohol metabolism causes a buildup of a compound called acetaldehyde, which is 30 times as toxic as alcohol and is a known carcinogen that causes facial flushing.

Individuals that flush have an enzyme deficiency that causes their body to not process alcohol the way it should. This causes an enormous accumulation of acetaldehyde. This accumulation and the symptoms it causes, are known as Alcohol Flush Reaction (AFR). AFR is caused by a genetic mutation.

Among other things, acetaldehyde causes inflammation and the skin to flush red, which is the most noticeable symptom of AFR. Alcohol Flush Reaction has been called many things: “Asian Flush”, “blushing”, “Asian glow” maybe even others like “alcohol tan”, and causes social anxiety and lowered confidence when drinking. In addition to the cosmetic effects, Alcohol Flush Reaction can cause dizziness, nausea, headache, increased heart rate and body temperature, and intensified hangover symptoms.

While intensified in those that experience an alcohol red face, any drinker may feel nausea and dizziness, even after just one drink. Acetaldehyde is responsible for these negative physical symptoms as well as hangover.

Flushing while drinking (acetaldehyde exposure) puts individuals at a higher risk of:

Gastric and esophageal cancer

Studies demonstrate that upper digestive tract cancer risk is greatly increased in people that experience facial blushing. Moderate drinkers that flush are still at over twice the risk of esophageal cancer as heavy drinkers that do not flush. One study shows that 35% of the patients flushed, but accounted for 69% of the esophageal cancer cases. This is due to increased acetaldehyde exposure. The “Asian Flush” cancer correlation has been very well researched around the globe.

Liver cirrhosis and failure

Studies show that there is a 60% higher risk of alcoholic cirrhosis in moderate drinkers that have facial flushing when compared to those that do not.

Alzheimer’s disease

Individuals that flush demonstrate a higher chance of getting the degenerative brain disease Alzheimer’s. Studies show that 48% of Alzheimer’s patients flushed whereas only 37% flushed in the control group without Alzheimer’s.

NBC News recently published an article about alcohol flush reaction. This article also helps to describe that a red face from drinking is not caused by an allergy but is the result of a mutation in acetaldehyde dehydrogenase 2.
