You’ll be fine. I’m on medication for a similar thing and just took my medication with me and chatted to the doctors about it. I understand TOCs do vary generally speaking, but something like this, where presumably any medication you’re on, like mine, has no side effects (or none that you’re experiencing anyway), won’t be an issue. I took a note from my GP too just underlining how the medication I’m on would be fine for driving trains and is non-drowsy etc. It just cuts out the middle man and speeds things up if they wanted to make enquiries.
I would say the only thing that would be an issue was if it wasn’t under control, so I’m basing all of the above on the fact that you’ve been diagnosed with Colitis, so it is under control if that makes sense? I’m taking Octasa, which is fundamentally just an anti-inflammatory I believe, so it’s worth looking at the meds you’re on and even if there are issues, you may be able to switch to something else.
The important thing is to be open and honest with the situation. Not least because IF you had issues in the future and needed time off etc, you already have on file that you suffer from colitis.
