I have a dermoid cyst on my left ovary and ibs too. i had unprotected sex yesterday and have had loose stools today could that be linked??

Dermoid Cyst Ovary: There is no connection I know of between an ovarian Dermoid cyst and an episode of diarrhea. With IBS, as you know, there can be periodic episodes of constipation/pain and diarrhea. The relationship of the diarrhea to a sexual encounter is not direct, but food/drink associated with the encounter could have played a role. IBS can fluctuate with life experiences.
