I did a SIBO Test about a year ago, and I barely elevated on the Methane portion (max was 10 and I hit 13). Dr wasn't too concerned.    

Have you looked into SIBO (Small Intestine Bacterial Overgrowth)?  Also, MCAS (Mast Cell Activation Syndrome)/histamine intolerance (they go together like a hand and glove).  Both of the above are common in the celiac community.

So tough for me when my symptoms are asymptomatic. Only excessive gas, floating stools and occasional discomfort in my lower right abdomen. These symptoms do not change, regardless of how I eat too:(  I'm sure that next week the GI doctor will discuss my findings and pathology results with me. It's at that time I may push for an MRI or CT scan of the abdomen. I prefer the MRI to avoid unnecessary radiation too. 

The problem with dairy isn't necessarily lactose which is the sugar component. It can be but the other issue and the more serious one from the standpoint of celiac disease is the protein casein. It can damage intestinal mucosa just like gluten. https://pmc.ncbi.nlm.nih.gov/articles/PMC1810502/

Thank you Trents! For the most part I have cut out Dairy as I drink Silk almond milk daily as an alternative!  I did have some corn Chex this morning with almond milk as that cereal is supposed to be fortified with vitamins and also gluten free so I hope that's ok! The only dairy I really have is a daily plain Yogurt which is lactose free and I only do that for the natural pre-pro biotics. Tried a slice of gluten free bread this morning......it was so so. I'll probably have another piece after my workout with some egg whites and avocado on top! Boy this stuff is hard, and I really want to try to do everything right because I have a little 2 year old girl to live for!  I also started taking Align Probiotics the day after my colonoscopy and I plan on only doing that for 30 days... I figure it can't hurt...
