lovetennis,
Welcome to the forum.
Glad you've found us, although I am sorry you have to be a part of this terrible club.
You've gotten some good advice already.
I think it's great that you are open to trying gluten free, I would also recommend going dairy free.
You'll probably hear the words SCD and Paleo spoken of here. IMO, Paleo is much better and is anti-inflammatory as well.
IMO, there are many things you can add to your bag of "tricks" besides meds: probiotics very important ( can you get your doc to prescribe VSL #3DS for you?), slippery elm powder, l-glutamine amino acid powder.
If any of these interest you, 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
naltrexone.
For more info on the protocol which has put me into remission,
please go to this link: https://www.healingwell.com/community/default.aspx?f=38&m=1666318 , and look at the 11th post.
I hope you feel better and let us know how we can help
you.
