loose stool

Hello. it has been 5 years, i have been diagnosed with non specific ulcerative colitis in the last part of my guts. I used to have blood in my stool, but now its gone. almost a year. Today i have other problems. I usually feel sick and want to trow out in the mornings, and first thing i do when i wake up is to run to toilet. My stool is fine, but from time to time, it is very loose, i have diarrhea and cant hold my poo. This cant happen any time with no actual reasons understandable foe me.
How can I fix this, can the reason be weak anus?

A weak anus is unusual, even with ulcerative colitis. If you haven't received multiple opinions from medical professionals, I might suggest going to a new specialist if your curent doctor can't help.
         The best reason to seek medical attention when you've got a chronic condition is when symptoms change. You should seek a medical opinion on this issue.

     I work in isolated conditons, and my #1 helper has Crohn's disease (and I had ulcerative colitis myself as a kid). The internal scarring and damage already done to your colon, plus any infection or inflammation, often makes people VERY sensitive to pain in their digestive system- I suspect that what would feel like mild cramps to many people with healthy digestion becomes crippling pain to people with scarring and inflammation, and thus it becomes so difficult to hold your bowels.

Regardless, go to the doctor if this persists more than a day or two.
