I have had food issues for many years but was finally diagnosed with UC about 6 years ago. I take Asacol and Remicade which have definitely helped.
about 2 years ago I was really feeling badly and after an endoscopy and colonoscopy the GI told me that I did not have Celiac disease but agreed when I suggested trying a gluten free diet. I learned quickly that you cannot do this diet partially, but had to commit to it completely.
In the last 2 years, each November I go into a Colitis flare. I have narrowed it down to the antibiotics I get when I get bronchitis/pneumonia each October or November and my flu shot.
I am still in my flare up but things are better than they were a couple of months ago.
I have found that eating a completely gluten free diet does help. The diet is difficult to be sure, and many days I have the “woe is me” attitude, but then I snap out of it. I can honestly say that I do not consume any known gluten. I have been CC’d on occasion, but that pain just mixes with my others.
My problems are made a little worse because I also have IBS, Lactose Intolerant, GERD and gastro-paresis. Because I digest my food so slowly, I often have pain and nausea, no matter what I eat. Once the food digests a little, the back and belly pain diminish, and my Zofran helps with nausea. My diet is so much more limited than just being gluten free. I can not eat fresh vegetables or fruit, any dairy, any tomato based products. Meat is hard to digest and I suspect nighshades are making me ill.
Some days I just don’t know what to eat and resort to canned chicken or tuna, gf pretzels, jello, gf bagels by Udi, fresh salmon, shrimp, beef broth. It all gets a little tiresome.
So yes, I think going gluten free has helped me a great deal. I would suggest that if you are thinking of doing this, you give it a 100% trial and see how you feel. Anything less than 100% won’t give you an accurate result.
