Uterine prolapse is a condition in which the uterus descends from its normal position along the vagina and the cervix reaches below the level of the sciatic spine, or even the uterus is completely prolapsed beyond the vaginal opening. The main cause of uterine prolapse is the weakening of the pelvic fascia, pelvic floor muscles and uterine ligaments. Common causes include: 1, age: with age, estrogen secretion decreases, the pelvic floor muscles relax and even atrophy and degeneration, the incidence of uterine prolapse increases significantly. 2, childbirth injury: especially vaginal delivery with forceps or fetal suction difficulties may cause excessive strain on the pelvic muscles and uterine ligaments and weaken the support capacity of the pelvic tissues, especially women with multiple vaginal deliveries are prone to uterine prolapse. If you participate in heavy physical labor too early after delivery, the pelvic tissues will not recover well, which will lead to different degrees of uterine downward migration. 3, chronic increase in abdominal pressure: chronic cough, fluid in the abdominal cavity, frequent heavy lifting or constipation and increase in abdominal pressure, can lead to uterine prolapse. Some obese women can also be caused by increased abdominal pressure resulting in uterine prolapse. 4, pelvic surgery history: pelvic surgery can destroy the pelvic support structure, damage the peripheral nerves, resulting in pelvic dysfunction and uterine prolapse. 5, congenital developmental abnormalities: a small number of unborn mothers have uterine prolapse because of poorly developed reproductive system support tissues. Uterine prolapse is mainly caused by age, childbirth injury, chronic abdominal pressure increase, pelvic surgery history and congenital dysplasia and other factors that cause the support capacity of the pelvic floor support tissues to weaken, of which childbirth injury is the most common. Daily strengthening of physical fitness and prevention can reduce the occurrence of uterine prolapse.
