A Real Allergy or Just an Intolerance

Real alcohol allergies are few and far between but the reactions might be severe. The things many people suppose to be alcohol allergy is really a reaction to an allergen in the alcohol. Prevalent allergens in alcohol consist of:







*histamines (frequently found in red wine)

*sulfites (typically found in white wines)

Individuals typically call alcohol intolerance an alcohol allergy-- and the other way around. Individuals who truly have a alcohol allergy should abstain from alcohol consumption.

What Causes A Person To Be Allergic to Alcohol?

Research into alcohol allergies is restricted. It has mainly focused on aldehyde dehydrogenase (ALDH2). ALDH2 is the enzyme that digests alcohol, transforming it into acetic acid or vinegar in the liver. Someone that has a vinegar allergy may have an extreme reaction after consuming alcohol. Research reveals that a gene change called a polymorphism, more common in people of Asian ancestry, inactivates the enzyme ALDH2. It's then impossible to convert alcohol into vinegar. This condition might be described as an ALDH2 insufficience.

addiction as a disease

Alcohol can even generate allergic responses or aggravate alreadying existing allergies. Researchers assume that bacteria and yeast in the alcohol produce histamines.

Individuals who conclude they have had a reaction to alcohol should see an allergy specialist.


Even a little bit of alcohol can cause signs and symptoms in individuals with real alcohol allergies. The symptoms might include stomach pains, a labored respiratory system, and even a respiratory system collapse.

Reactions to different ingredients in mixed drinks will cause different signs and symptoms. For instance:.

*someone who is allergic to sulfites may experience hives or anaphylaxis

*someone who is allergic to histamines might endure nasal swelling and blockage

*alcohol high in sulfates may intensify asthmatic signs in people with asthma

*alcohol may raise the reaction to food allergies

Other symptoms associated with the components discovered in beverages containing alcohol might include:.


*nasal blockage consisting of stuffy or runny nose

*abdominal pain

*a feeling of sickness

*throwing up

*heartburn symptoms

*quickened heartbeat

*Rashes and Alcohol Flush Reaction

Some persons might encounter face reddening (flushing) when they drink alcohol. This alcohol flush reaction is more prevalent in those of Asian descent, due to polymorphism. Facial flushing is not an allergic reaction, simply an adverse effects of alcohol intake in some individuals.

According to a 2010 research study released in BMC Evolutionary Biology, the gene modification responsible for the polymorphism is related to the domestication of rice in southern China several centuries in the past. People with the altered gene are at reduced risk for alcoholism than others, mostly thanks to the uncomfortable response that occurs after consuming alcohol.

Although reddening of the face might be a result in individuals with an ALDH2 deficit, some people form red, warm, blotchy skin after consuming an alcoholic drink. Sulfur dioxide is typically utilized to process and help protect alcohol.


The only way to prevent symptoms of an alcohol allergy is to avoid alcohol. Individuals who've had an extreme allergic reaction to certain foods should use a medical alert pendant and ask their physician if they need to carry an emergency situation epinephrine (adrenaline) auto-injector like an EpiPen in case of a severe allergic reaction.

What the majority of individuals suppose to be alcohol allergy is in fact a reaction to an irritant in the alcohol. Somebody who has a vinegar allergy may have a severe reaction after consuming alcohol. Alcohol can even set off allergic responses or irritate already existing allergies. Facial reddening is not an allergic reaction, just a side effect of alcohol consumption in some individuals.

The only way to abstain from signs of an alcohol allergy is to abstain from alcohol.
