Gaining Weight Since Diagnosis in Coping with Celiac Disease Posted December 5, 2006 · Report to Admin Hi, I'm new here. I was diagnosed 4/05 and since going total gluten free except for accidental contaminations, I have gained about 20 pounds. I don't know how to get rid of it and don't want to eat gluten in order to return to my normal weight. Also, wondered if anyone else has had problems with a skin condition called, granuloma annulara. Thanks for any help.
