When your pelvic floor muscles stretch and weaken, there is inadequate support for the uterus. This can cause it to descend into the vaginal canal, which is known as prolapse.
Uterine and/or bladder prolapse is most common in postmenopausal women who’d have vaginal deliveries. The effects of gravity, loss of estrogen and the strain caused by one or more pregnancies can cause the pelvic floor muscles and tissues to weaken. Loss of muscle tone is also a factor and in rare cases, prolapse can be caused by a tumor in the pelvic cavity.
Other factors can cause prolapse, including obesity, chronic obstructive pulmonary disease and chronic constipation, as these health factors can place undo strain on the pelvic muscles and connective tissue.
