Uterine Prolapse - What Causes Prolapse Of Uterus?

Having discussed the meaning of uterine prolapse and its symptoms in the previous post, let's see now what causes the prolapse of uterus.

Why does uterine prolapse occur?

Common causes of uterine prolapse are-

1. Age Factor

Most common cause of uterine prolapse is the weakening of pelvic musculature (supports of the uterus) after menopause, as a result of oestrogen deficiency.

2. Birth Injury

Injury to the supporting structures of uterus during vaginal delivery is another important factor. Such injury can be caused by-
  • Bear down efforts before full dilatation of cervix.
  • Prolonged labor.
  • Application of forceps before full dilation of cervix.
  • Downward pressure on uterine fundus to deliver placenta.
  • Repeated childbirths at frequent intervals.
  • Resumption of heavy work soon after delivery.
  • Delivery of a big baby.
  • Ill-nourished and weak women.
3. Increased intra-abdominal pressure due to:
  • Chronic cough or 
  • Constipation.
4. Increased weight of uterus due to fibroid.

5. Undernutrition

6. Congenital weakness of pelvic floor muscles, in rare cases, when prolapse is seen in unmarried women (usually associated with spina bifida occulta and split pelvis).
