Alcohol allergies: Symptoms, treatments, and alcohol intolerance

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 types of sulfites might also trigger an asthmatic attack if you have asthma. 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. If you have this variant, it causes your body to produce less active ALDH2.

Certain medications can also interfere with liver function, making it more difficult for your body to process alcohol. For instance, if you take acetaminophen (Tylenol) regularly and also consume alcohol, it can increase the risk of liver damage. A sign that you may have an intolerance is that you have symptoms no matter what type of alcohol you drink.

Symptoms and Causes

• Severe flushing can be very uncomfortable, but it is not dangerous.
• Because acetaldehyde is toxic and carcinogenic (causing cancer), avoiding alcohol altogether is the only option that medical professionals will recommend.
• If you experience a mild allergic reaction, over-the-counter oral antihistamines may be enough to treat it.
• If you have a food allergy or sensitivity, it can trigger an immune system reaction that can make it more difficult for your body to metabolize alcohol.

Other ingredients typically found in alcoholic drinks can cause intolerance reactions, especially those in beer or wine. Symptoms of an alcohol allergy include rashes, itchiness, swelling and severe stomach cramps. Allergy symptoms are often more painful and uncomfortable than alcohol intolerance symptoms. In rare cases, if untreated, an alcohol allergy can be life-threatening. Alcohol intolerance can be extremely frustrating to people who like what causes alcohol intolerance to drink alcohol but can also affect those who do not. This condition causes a reaction to alcohol, like a hangover but occurs almost immediately when using alcohol.

Unfortunately, the only treatment for alcohol intolerance is avoiding alcohol. No drug will help you avoid the symptoms of alcohol intolerance or lessen your cancer risk. The symptoms of histamine intolerance are similar to an allergic reaction. For example, potential symptoms include red and itchy skin, nasal congestion, shortness of breath, abdominal pain, and diarrhea.

• However, they can come on suddenly, and a person could develop an alcohol allergy at any point in their life.
• Some people may find relief with diamine oxidase (DAO) supplements, which may assist your body in breaking down histamines.
• So, Dr Sim urges anyone who knows they’re allergic to certain foods, particularly grains, to be aware they could be in drinks, too.

Is alcohol allergy treatable?

In someone with alcohol intolerance, the enzyme that breaks down acetaldehyde doesn’t work correctly, leading to a buildup of acetaldehyde. This toxic by-product of alcohol metabolism quickly triggers a range of symptoms that can be both unpleasant and potentially harmful. In some cases, over-the-counter or prescribed medications might help alleviate symptoms. If you develop symptoms after drinking alcohol, make an appointment with your doctor.
