Question: how do you know if you're allergic to beer?
Answer: Beer sensitivity does cause symptoms similar to those from allergic reactions. They include hives, nausea or vomiting, diarrhea, sneezing, wheezing and abdominal pain. “Most common reactions to beer are specific to types of grains, modified grain proteins, hops, yeast, molds or barleys,” says Dr. Rood.
