<human>: I've been told that I'm allergic to gluten. Is this true, and how do I know for sure?
<bot>: Yes, it is true that you may be allergic to gluten. Gluten is a protein found in wheat, rye, and barley. It can cause digestive problems such as bloating, gas, diarrhea, constipation, and other symptoms if you are allergic to it. To test for gluten allergy, you should consult with your doctor or allergist to see if you have an allergy to gluten. They will likely perform skin tests or blood tests to confirm the diagnosis.
