What exactly all can UC cause?

Shh no one answer her, it'll just put more worry on her mind!

Depression & anxiety !

People with uc are more likely to have vision issues, skin rashes, more prone to blood clots are the ones I hear most often from nurses.

"Less commonly, ulcerative colitis causes problems with the skin, joints, eyes, kidneys, or liver, which are most likely due to abnormal inflammation." ghr.nlm.nih.gov/condition/ulcerative-colitis

A better question would be, what other conditions do people here have as a result of UC. Me -blood clots, skin issues, depression/anxiety, etc etc

UC is the curse that keeps on giving!

at the same time, think how many serious diseases people develop out of the blue without having ever been diagnosed with uc. Everything is a matter of chance, like the plane you take, those poor people yesterday probably didn't have uc.
