There are several soft organs inside the pelvis region which are held in their place by the muscles and tissues in the area. As the muscles lose strength, the organs start to fall down causing pelvic organ prolapse. Almost every woman (and some men), suffer from pelvic organ prolapse. Women get it mainly due to the pressure laid by growing baby on the pelvic region during pregnancy and vaginal delivery that tears a lot of muscles and tissues. Multiple vaginal deliveries are going to make things worse unless the pelvic floor muscles are worked out and strengthened.
