Beer Allergy Symptoms

Some people experience adverse reactions, beyond drunkenness and simple hangover, when drinking beer; they wonder if they are allergic to beer. A true beer allergy is rare. Instead, an allergy to one of the many ingredients in the beer is more likely.

Types of Potential Allergens in Beer

Beer can contain wheat, hops, barley, rye, or corn and yeast. Food allergy reactions to these can be as mild as hives or as severe as anaphylaxis. A yeast allergy can also make you tired.

Features of Non-Allergic Rhinitis

Some people think they are allergic to beer because their nose becomes congested after consumption. This is probably more likely due to nasal passages dilating and thus causing an increase in mucus production.

Features of Histamine Reaction

During the fermentation process, histamines can be produced by the yeast. A histamine reaction can be similar to an allergic reaction, as it causes hives, itching, wheezing, sneezing, and red and itchy eyes.

Effects of Beer on Celiac Disease

People suffering from celiac disease are sensitive to gluten found in wheat, rye, and barley, which are all used in making beer. Reactions to gluten consumption easily mistaken for a beer allergy are gastrointestinal upsets, including diarrhea and stomach pain.

Other Serious Effects of Beer Allergies

People suffering from the rare beer allergy may also experience swelling of the face, tongue, throat or lips.
