It may be difficult to distinguish these symptoms from alcohol side effects. And the side effects of alcohol may exacerbate allergy symptoms, too. Alcohol intolerance is a genetic metabolic disorder that is triggered by consuming alcohol. The culprit is a substance called acetaldehyde — a toxic product of alcohol metabolism that is produced in the body as it breaks down the alcohol in your system. Many people think that alcohol allergy and alcohol intolerance are the same thing, but they’re not. In fact, only alcohol intolerance causes the alcohol flush reaction.
- Allergy testing should always be done in a medical setting.
- On top of that, your doctor may recommend avoiding tobacco (including second-hand smoke), which can add to the acetaldehyde levels in your body.
- It is not exactly known what causes alcohol intolerance, but research suggests a number of factors.
- Alcohol intolerance is often mistaken for alcohol allergy, but the former is distinctly different from the latter.
- For genetic or metabolic reasons, your body has trouble breaking down ethanol — the alcohol — in wine.
- People participate in clinical trials for a variety of reasons.
In some cases, they might use an oral challenge test to diagnose an allergy or intolerance. In this procedure, they will ask you to consume a sample of your suspected trigger. Some people experience allergy-like reactions to sulfites. Some types of sulfites might also trigger an asthmatic attack if you have asthma. If you have this variant, it causes your body to produce less active ALDH2.

Your body uses an enzyme called aldehyde dehydrogenase, or ALDH2, to break down acetaldehyde. However, in some people, ALDH2 does not work correctly, resulting in alcohol intolerance. For mild intolerances, you should either avoid alcohol, limit how much you drink or avoid certain types of alcohol with ingredients that may cause a reaction. However, if you have a serious allergy-like reaction following drinking alcohol, consult a medical professional. An enzyme known as aldehyde dehydrogenase is responsible for turning ethanol into acetic acid within the liver.
What diseases cause intolerance to alcohol?
The best-known condition to cause alcohol intolerance is Hodgkin's lymphoma; however, other conditions may also cause it. Alcohol intolerance is still normally uncommon in people with these types of conditions.
If you keep an signs of alcohol allergies and allergy journal, you should be able to determine which activities combined with certain amounts of alcohol trigger symptoms and side effects. This is different from alcohol flush reaction, which is when the body breaks down alcohol into acetaldehyde at an accelerated rate. Alcohol flush reaction shares several symptoms with alcohol intolerance, but the causes are completely different.
What are the symptoms of alcohol intolerance?
Consult doctors, other trusted medical professionals, and patient organizations. Use ClincalTrials.gov button below to search for studies by disease, terms, or country. Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments. However, certain food groups also have benefits when it comes to helping with the discomfort of withdrawal symptoms and detoxification.
It happens as the blood vessels in the face dilate because of the body’s inability to manage all the toxins in an alcoholic beverage. If you have a true alcohol allergy, even small amounts of alcohol can cause symptoms. This is an allergic reaction that can be life-threatening.

Some people may also be allergic to ingredients in alcoholic beverages, such as wheat in beer or tannins in wine. Wine allergy symptoms are also similar to seasonal allergy symptoms, though symptoms around the mouth and tongue may be the most dominant ones.
If you have an alcohol allergy, your immune system will overreact to alcohol. If you have an alcohol intolerance, your digestive system does not process alcohol properly. You can also react to certain alcoholic beverages if you are intolerant to histamine or sulfites. In very rare cases, a reaction to alcohol can be a sign of Hodgkin lymphoma. 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.
