I won’t be confident rather grateful to have this subside
Yeah, lots of mucous is always a sign of a flare for me, especially when it's coming out alone. I agree with Q around rectal meds and early intervention when symptoms are mild. Diet can work well in combo with the rectal meds (e.g., plant based diet or gluten/dairy free). Keeping a food diary and tailoring diet to you is key.
Mesalamine is the least intense of all the meds we have for UC so if you respond consider yourself lucky and don't get overconfident around not taking meds.
