Hi Sanja6,
I wonder if it could be some absorption issue, but after 16 years with a JPouch, you would probably recognize that. Could you have a bladder infection? The urgency you described could be a symptom of a bladder issue/infection. This is a long shot, but you may want to get your sugar checked, when I developed diabetes - I drank tons of water and needed to urinate often. I of course don’t want to scare you. I got diabetes totally unrelated to my Crohn’s, but rather steroid use and weight gain and age. By no means do I have any authority to evaluate that, but you may want to go to your GI doctor or primary care doctor soon. Good luck - Doug
