There's definitely a lot of autoimmune type diseases that have mental and/or physical components. Your endocrine system, sympathetic nervous system and central nervous system are all wired up together so of course changes/disfunctions in one can cause symptoms in another. And there's lots of pathogens that cause "flu-like" symptoms, so it makes sense there could be multiple things that cause "UC-like" symptoms.
