i think it's possible the two could be connected considering that many people with ibs have their symptoms worsen during their cycle. i know uc isn't the same thing but there are some of the same systems involved.
is there a connection between menstrual cycle and ulcerative colitis? . i was diagnosed with u. c. 20 years ago. soon after i married i was afraid that birth control pills would be ineffective because of diarrhea that i had. i decided to switch to the depo provera injection. after some time the u. c. became controlled and i needed no additional medication for u. c. i have had regular colonoscopies and have scar tissue but no on-going disease process. i have symptoms when i have regular periods and during the last 20 weeks of both pregnancies.
