I haven't noticed any increase, but I drink a lot of water every day so pee a lot anyway. It did increase after I started pred, but only back to what's normal for me, and I attribute that to my colon actually working properly again and not having diarrhea.
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Eased for ~3 weeks in December, possibly b/c of probiotic use?
Returned in January 2009 (with a vengeance), diagnosed with pancolitis on January 30.
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa nightly,
40mg 30mg 20mg 15mg 10mg of Prednisone (quick taper), Culturelle probiotic, and Zoloft (25 mg).
