The first (5-ASA) and second line (steroid) therapies for UC are far safer than smoking, and may be effective in knocking out your inflammation and preventing proximal disease extension in the future. Speaking from experience
, proximal disease extension is a concern with proctitis.
There has been some debate as to whether low-dose smoking is as unsafe as immunomodulators and/or biologics for certain folks, but you’re not even close to making a decision like that, yet.
Once you have UC, you always have UC. Medications only tame the inflammation. Therefore, it is a good idea to be on a medication to quickly induce remission and then maintain remission. Medications will be recommended for LIFE with UC. Welcome to the club. I know.
Based on your post, I'll assume you don’t want to choose smoking as a means to induce and maintain remission, so here is my advice to you:
1. Max dose of oral 5-ASA daily
2. Max dose of rectal 5-ASA nightly
3. Reassess in 4-6 weeks
Once you’re able to achieve a solid remission, you may be able to taper the meds to a lower maintenance dose!
Good luck
