Hi, I'm new to the boards. Could my symptoms be Celiac's disease? I almost constantly feel gassy and bloated, and I have diarrhea almost on a daily basis, combined with bouts of constipation. I have also been feeling nauseated after everything I eat lately. For years I believed I had lactose intolerance, but I have been dairy free for several days and I still feel ill. I am constantly fatigued, I can sleep for 12 hours a day and still feel tired. A friend of mine was recently diagnosed with Celiac's, and my symptoms seem similar. Could this be my problem? It would be wonderful to finally figure out why I have been feeling terrible for years. Thanks!
