Gross Questions...new Symptom in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted February 28, 2013 · Report to Admin Ok guys,this post is a little graphic. Many of you know I have been having gut problems for quite some time. You can look back in my history to see my symptoms. I have to admit, I am currently Euthyroid and I do feel quite a bit better, but I still have this constant abnormal feeling and my GI Issues are still there. Recently I started having huge greyish colored bowel movements accompanied with incomplete evacuation. The movements smell terrible almost like a vomit/sulphur smell, so does my gas. The movements themselves are somewhat formed and somewhat not. They are litteraly that big they clog the toliet. They are also extremely messy. They are large even if I don't eat much. I rarely get full blown D just what I describe above most of the time 7 days a week. I have had 2 celiac panels, both of which were negative beside one showing a slightly elevated IgG at 11 which was 2 points above normal. All my bloodwork is fine (ie. liver panel, kidney panel) I had a colonoscopy and that was fine as well except for one polyp. Any idea what the hell can be cause these bowel troubles.
