"What actually damages the colon in UC?"
Uc is believed to be an autoimmune disorder (or at least immune deficiency) where your immune system goes haywire and starts attacking self, which causes inflammation, bleeding, and ulceration within the large intestine. That in turn causes diarrhea, mucus, urgency, and frequent bms. We're not sure exactly what the immune system is targeting for an attack (is it something a common bacteria?, or a bacteria/virus/fungus that it cannot destroy) what triggers that sudden attack. There's some theories thrown around (an immune resistant type of MAP/tuberculosis bacteria, a fungus, etc.). However the jury is still deliberating on that one.
