Unfortunately, if the body can’t effectively process and break down these histamines, it creates a buildup, which can cause these uncomfortable skin conditions, he explains. While alcohol allergies are rare, the consequences of this condition can be serious. For diagnosis and prevention of either condition, schedule an appointment with a Baptist Health provider. Depending on whether a person has an alcohol allergy or intolerance, they may need to avoid alcohol entirely. An alcohol allergy and alcohol intolerance are two different conditions. If people experience symptoms after drinking alcohol, they should speak with a doctor for further advice. An allergic reaction might not occur the first time a person encounters an allergen.

While a common misnomer for alcohol sensitivity is “alcohol intolerance,” which implies that a person gets drunk quickly, alcohol sensitivity isn’t just a low tolerance to alcohol. Although a true alcohol allergy is rare, and the reaction can be severe, most allergic reactions to alcohol are due to an ingredient in alcohol. Every person’s body chemistry and make-up is different, so a person’s response to alcohol can vary greatly. An enzyme known as aldehyde dehydrogenase is responsible for turning ethanol into acetic acid within the liver. Those of Asian ancestry may have the less-active variant of ALDH2, making it more difficult for them to properly digest alcohol. ALDH2 Deficiency, as it is known, is a common cause of alcohol intolerance.

However, in people with an alcohol allergy, the system mistakenly produces antibodies to attack alcohol following exposure to the substance, triggering various symptoms. We will also look at what causes alcohol allergies and review the differences between alcohol allergy and intolerance. The analysis of your DNA will let you know if you have an unfavourable variant of ALDH2 or ADH1 gene , which can cause acetaldehyde build-up and consequently, alcohol intolerance. The main advantage of our metabolism-related DNA test is that it analyses more than just alcohol metabolism.

An alcohol intolerance or intolerance to alcohol is not always responsible for symptoms occurring after drinking alcohol. With an alcohol allergy, a person’s immune system overreacts to alcohol.

Is There Treatment For An Alcohol Allergy?

Certain diseases can affect how well alcohol dehydrogenase functions. Hodgkin’s lymphoma, ovarian cancer, breast cancer and other diseases can all cause a sudden onset of alcohol intolerance in those who never before experienced difficulty drinking. The sudden development of alcohol intolerance does not necessarily mean that a new disease is present.

People with an alcohol allergy experience a reaction after as little as 1 milliliter of pure alcohol or a mouthful of wine or beer . Why some people experience allergic reactions to alcohol – when small amounts are already produced by the body naturally – is yet unknown to researchers. However, in some cases, severe reactions to alcohol are mistaken for allergies when the culprit is Hodgkin’s Lymphoma, a cancer of the lymph nodes. In some cases, over-the-counter or prescribed medications might help alleviate symptoms. Alcohol intolerance, also known as alcohol sensitivity, is typically caused by a change that affects an enzyme called alcohol dehydrogenase.

What Are the Symptoms Of An Alcohol Allergy?

It’s also found in many foods and beverages, especially fermented products. For example, aged cheese, smoked meats, sauerkraut, wine, and beer tend to be high in histamines. Aldehyde dehydrogenase is an enzyme that your body uses to digest alcohol.
