The main causes of pelvic support problems are pregnancy, childbirth and aging. The weight of the baby during pregnancy creates tremendous pressure on the pelvic tissue and muscles. Then, as the baby passes through the vagina during childbirth, the support of the pelvic floor muscles and ligaments may become damaged and weakened.
In later years, when a woman goes through menopause, the loss of estrogen worsens the strength of these delicate tissues. In some women, a familial (hereditary) factor seems to predispose to this problem even without childbirth. The causes may be:
1) Unusual weakening of the vaginal tissue after menopause
2) Abnormal increases in abdominal pressure due to coughing, heaving lifting, obesity, or constipation
3) Hereditary weakness of tissue.
