Welcome to the forum.
Glad you're willing to try gluten free.
There are other easy things you can try as well, and if you're interested,
there are things IMO that you can control, which will have a direct impact on
your disease, the symptoms you experience and their severity.
I was able to control my UC into remission through various
supplements, probiotics, diet modification, and LDN , low dose
For more info on the protocol which has put me into remission,
