"Beer allergy" is a recently discovered allergy. Although it is not as common as food allergies like "milk allergy," its incidence has been on the rise in recent years. Moreover, because it is not known that beer can also cause allergies, patients themselves, their families, and even some inexperienced doctors may be at a loss when faced with sudden, severe allergic reactions.
Symptoms of "beer allergy" include: swelling of the throat and tongue, numbness or a burning sensation in the mouth and lips, severe shortness of breath, and even fainting. These allergic reactions generally occur about half an hour after drinking beer, and if not treated promptly, severe cases can be life-threatening.
"Beer allergy" does not necessarily occur in first-time beer drinkers. A 30-year-old man from Spain had previously consumed beer multiple times without any adverse reactions, but 10 days ago, just a small glass of beer nearly cost him his life.
In view of the fact that a large proportion of adverse reactions occur when beer is consumed with peanuts or shellfish, experts recommend that beer lovers should best avoid these two types of snacks when drinking beer.
Some allergy treatment specialists in Spain conducted a special study and found that the main ingredient in beer, barley, is what causes beer allergies. In fact, a skin test can quickly confirm whether a person is allergic to beer. It is worth mentioning that most people who are allergic to beer may also have adverse reactions to other barley products. Experts have also confirmed that genetic factors are among the causes of "beer allergy," so individuals with a family history must be particularly cautious when drinking beer.
