These compounds are often added to beer and wine to limit the growth of yeast and act as a preservative. Common sulfites include potassium bisulfite or potassium metabisulfite.

- Choosing drinks with fewer additives, such as clear spirits with minimal preservatives, may also lessen reactions.

Some individuals may experience headaches shortly after consuming alcohol, often due to the dilation of blood vessels in the brain or the buildup of acetaldehyde. Wine, beer, and certain cocktails can contain histamine and other fermentation compounds that can worsen migraines or asthma symptoms.

Intolerances can be genetic and are much more common than allergies, and may be more likely to affect people of East Asian descent, Factor said. Your immune system may experience changes as you age, as well as what is alcoholism the way your body metabolizes substances. Changes in diet or a health condition may also contribute to suddenly developing an allergy to alcohol. While alcohol allergies are rare, the consequences of this condition can be serious.

Some individuals with alcohol intolerance experience symptoms from fermented foods like kimchi, kombucha, or aged cheeses due to shared compounds like histamines. Experiment by eliminating these foods temporarily to see if symptoms improve. Alcohol intolerance often stems from genetic factors, particularly the presence of deficient or inactive aldehyde dehydrogenase (ALDH2) enzymes.
If you’re deficient in ALDH2, your body struggles to what is alcohol intolerance break down the toxins in alcohol. This is because, when you drink alcohol, it’s broken down in your body into a chemical called acetaldehyde. However, for people with alcohol intolerance, this process is impaired because the ALDH2 is less active, causing acetaldehyde to build up in the blood and tissues, causing symptoms. Diagnosing alcohol intolerance involves several steps that focus on understanding a person’s medical history, symptoms, and physical response to alcohol.


This test measures the concentration of IgE antibodies in the blood that indicates a sensitization to a specific allergen. If you experience severe symptoms of alcohol allergy or intolerance it is important you limit or abstain from alcohol while you seek a diagnosis from your GP or allergy specialist. Some sufferers may experience alcohol intolerance symptoms shortly after consuming alcohol – roughly 20 or 30 minutes – finding a runny nose and flushed face occurring first.

That flushed face you have isn’t necessarily because you’ve had a few drinks; it could mean you have an alcohol intolerance.
