Alcohol and facial flushing
If your face turns red after a couple glasses of wine, you’re not alone. Many people experience facial flushing when they drink alcohol. The technical term for this condition is “alcohol flush reaction.”
Most of the time, the flushing happens because you have trouble digesting alcohol completely.
People who flush when they drink might have a faulty version of the aldehyde dehydrogenase 2 (ALDH2) gene. ALDH2 is an enzyme in your body that helps break down a substance in alcohol called acetaldehyde.
Too much acetaldehyde may cause a red face and other symptoms.
Read on to learn more about why flushing happens and what you can do about it.
Scientists estimate that there are at least
People of Japanese, Chinese, and Korean descent are more likely to have alcohol flush reaction. At least
In fact, the red face phenomenon is commonly referred to as “the Asian flush” or the “Asian glow.”
Some research has also shown people of Jewish origin might also be more likely to have an ALDH2 mutation.
It’s not known why certain populations are more likely to have this problem, but it’s genetic and can be passed on by one or both parents.
ALDH2 normally works to break down acetaldehyde. When a genetic change affects this enzyme, it doesn’t do its job.
An ALDH2 deficiency causes more acetaldehyde to build up in your body. Too much acetaldehyde can make you intolerant to alcohol.
Flushing is one symptom, but people with this condition might also experience:
- rapid heartbeat
While the flushing itself isn’t harmful, it may be a warning sign of other risks.
Scientists looked at 1,763 Korean men and found the “flushers” who drank more than four alcoholic beverages a week had a greater risk of developing high blood pressure compared to those who didn’t drink at all.
But, the “non-flushers” were only more likely to have high blood pressure if they had more than eight drinks a week.
Having high blood pressure can increase your chances of heart disease and stroke.
Some doctors believe that the flushing effect might be helpful in identifying those at risk for these diseases.
Medicines called histamine-2 (H2) blockers can control facial flushing. These drugs work by slowing the breakdown of alcohol to acetaldehyde in your bloodstream. Common H2 blockers include:
- Zantac 360
Brimonidine is another popular treatment for facial flushing. It’s a topical therapy that lessens facial redness temporarily. The medicine works by reducing the size of very small blood vessels.
The U.S. Food and Drug Administration (FDA) approved brimonidine for the treatment of rosacea — a skin condition that causes redness and small bumps on the face.
Another topical cream, oxymetazoline, was approved in 2017 to treat rosacea. It may help facial redness by narrowing blood vessels in the skin.
Some people also use lasers and light-based therapies to reduce redness. Treatments can help improve the look of visible blood vessels.
It’s important to know that therapies to help flushing don’t address the ALDH2 deficiency. They can actually mask important symptoms that could signal a problem.
The only way to prevent facial flushing from drinking is to avoid or limit your alcohol consumption. This might be a good idea, even if you don’t have a problem with turning red.
According to the World Health Organization (WHO), alcohol is responsible for more than
WHO says that alcohol is a “causal factor” in more than
Too much alcohol can increase your risk for developing a host of medical problems, including:
- liver disease
- certain cancers
- high blood pressure
- heart disease or stroke
- memory problems
- digestive issues
- alcohol dependence
If you do drink, try to drink moderately. The
Medicines that disguise the symptoms of alcohol intolerance may make you feel like you can drink more than you should. This can be dangerous, especially if you have an ALDH2 deficiency.
Remember, flushing in the face may be a sign that you should stop drinking.
Facial flushing while drinking is usually due to an ALDH2 deficiency, which may make alcohol consumption more harmful to your health. People of Asian and Jewish descent are more likely to have this problem.
While treatments may hide the redness, they only cover up your symptoms. If you experience facial flushing while drinking, you should try to limit or avoid alcohol.
Talk to your doctor if you think you might have an ALDH2 deficiency. Tests are available to confirm that you have the altered gene.
