Running/high intensity workouts

About this time last year, I decided to take up running and got to a place where I was running several miles at a time a couple of times a week. Nothing too crazy but I really enjoyed it. Shortly after, I started having flare symptoms (after being in remission for a couple of years) that quickly escalated to hospitalizations/biologics/infections, the whole thing. Became incredibly weak and malnourished, and obviously stopped running/working out for a long while. I’ve been feeling much better for several months now and in the last month or so, I decided to start back running. But now I’ve started to notice very mild UC symptoms coming back (increased gas, some mucus). Is it possible my body is being triggered by running/high intensity workouts? Or is this just a weird coincidence? Has anyone else noticed this association?
