Do u want firmer or looser stools for bm not to get stuck in a rectocele? seems the more fiber and water makes the bm too big around and gets stuck

A "firm" fix needed: It sounds like you are at "loose" ends about this problem and it needs a "firm" fix such as a surgical repair of the rectocele which can be done by consulting a GYN MD.

Fix: You want to try to fix that recto else before it gets worse or you get older

You want a soft BM: It may have to be slightly loose to accommodate the rectocele. You can help by pushing up on the skin between the anus and the vagina. Another maneuver that helps is inserting 2 or more fingers into the vagina and pushing back toward the spine and rectum to keep the rectocele from getting filled. Adding glycolax (generic Miralax) helps to keep the stool loose.
