Many patients wonder about this! After your uterus is removed (hysterectomy) all the normal organs that surround the uterus simply fill the position previously occupied by the uterus. Mostly it is bowel that fills the space, as there is lots of small and large bowel immediately adjacent to the uterus. Bladder and bowel following hysterectomy generally have more space to function normally particularly if the uterus is bigger then usual which frequently happens with fibroids, adenomyosis and other conditions causing heavy periods.
