Re: Could it be?
At the very least, it sounds like IBS...but UC can start like you describe if one has very very mild inflammation.
What meds are you on at this point for whatever?
How are your eating habits? Are you consuming any foods/drinks with artificial sweeteners?
Have you kept a food diary to see if there's any connection?
Are you a smoker? Have you recently quit?
It's all a matter of perspective!
