Welcome to the forum.
I find it interesting that your doc suggested going gluten and dairy free.
For many of us, those definitely cause problems and an aggravation of symptoms.
I am a strong believer in the diet-UC connection ( as far as aggravation of symptoms), and that's the reason I follow the Paleo diet, as it is anti-inflammatory.
I also believe in the importance of certain supplements: probiotics and lots of them, Slippery elm powder, L-glutamine amino acid powder as well.
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,
