The liver breaks down the alcohol (ethanol) that we drink and converts it to a chemical called acetaldehyde. Severe allergic reactions have been described in people with allergies to proteins within grapes, yeast, hops, barley and wheat. Furthermore, fining agents (such as egg or seafood proteins) are sometimes used to remove fine particles. Whether these occur in sufficient amounts to trigger allergic reactions is unknown. Histamine – this component is found in variable quantity in fermented products, which include beer and wines. The body, during digestion, produces enzymes known as diamine oxidase (DAO) in order to break down high histamine levels contained in ethanol beverages and other products.
- The doctor may refer the person to an allergy specialist for further testing and treatment.
- People often call alcohol intolerance an alcohol allergy, and vice versa.
- Other allergens present in alcoholic beverages in high quantity include; wheat, barley, hops, grapes, egg protein, yeast, sodium metabisulphites, rye, and gluten.
- Occasionally, a doctor may ask a person to consume alcohol in a medical setting and observe any reactions or symptoms.
Alcohol intolerance occurs when your body doesn’t have the proper enzymes to break down (metabolize) the toxins in alcohol. This is caused by inherited (genetic) traits most often found in Asians. When it comes to allergies to any component of an alcoholic drink, you must never consume it. Symptoms of an allergic reaction to LTP usually appear within minutes and include swelling, itchiness, digestive problems, breathing difficulties and, in extreme cases, anaphylaxis.
Who might have alcohol intolerance?
To date, there is little strong evidence of this, though distillation is likely to leave behind only negligible amounts of the proteins from the corn, if any. Some people may even have reactions to grapes or corn used to make wine and distilled liquors. Treatment providers are available 24/7 to answer your questions about rehab, whether it’s for you or a loved one.
Due again to the reaction from histamines, it’s not uncommon to experience swelling (think Will Smith in Hitch) when you have an alcohol intolerance. While rare, yeast allergy can cause an allergic reaction in some people. If in doubt, ask your allergy specialist for advice about the types of alcoholic beverages you can or cannot drink. People with mold or yeast allergies may have an allergic reaction to the brewer’s yeast used to make fermented beverages like beer, wine, and hard cider. Sulfites naturally found in wine and beer can cause asthma symptoms in people who are sensitive to sulfites.
What is the difference between alcohol allergy and intolerance?
Alcohol flushing syndrome is a major sign of alcohol intolerance. Your face, neck and chest become warm and pink or red right after you drink alcohol. It means you have to take great care in reading labels and choosing foods and drinks. If you’re allergic to a specific grain, beer won’t be your only problem. You’ll also experience symptoms when you eat other food products containing that allergen.
So, people are typically born with a tendency for alcohol intolerance, which also runs in groups of people who are more closely genetically related. For example, people of Asian descent tend to have lower levels of ALDH. People with alcohol intolerance may notice one or more of these symptoms after taking a few sips of alcohol. Others might only develop them shortly after finishing 1 or 2 drinks.
Mechanism of Reactions to Ethanol
Often it’s facial swelling of the lips and tongue, says Dr. Glatter. The medication is injected to quickly relax muscles to open up airways. By Kathi Valeii

Alcohol intolerance is a genetic condition where an individual’s digestive system cannot properly break down the substance. An allergic reaction might not occur the first time a person encounters an allergen. However, they can come on suddenly, and a person could develop an alcohol allergy at any point in their life.
