Yeah, Endometriosis will cause frequent urination. When endometrial tissue implants are on the bladder, during the time which corresponds to endometrial shedding, these tissues will also swell and bleed causing sensations of pelvic fullness and pain which compels one to visit the bathroom more frequently. If the implants are on the bowel, more frequent stools may be expected from the inflammation too. The location at which this tissue takes hold may be different for every individual.
