<<Disclaimer: Verify this information before applying it to your situation.>> My husband has Celiac disease. For a month now, he has been gagging involuntarily (as if he was going to vomit) several times a day. Could this be related to his Celiac disease? Do Celiacs ever gag and/or experience nausea? If this has happened to you, I would appreciate hearing from you. I'm trying to reassure myself that it is nothing serious. Holly
