Uterine prolapse is a common gynecological condition, primarily caused by damage to the pelvic floor tissues during childbirth. As the fetus descends during labor, it can damage the pelvic floor muscles and fascia, leading to a reduction in their supportive strength, which in turn causes the prolapse of the uterus and vagina. Additionally, aging is another main cause of uterine prolapse. As age increases, relaxation of the cervix, various uterine ligaments, and pelvic floor fascial muscles also contribute significantly to uterine prolapse.

Natural childbirth uterine prolapse manifestations

After vaginal childbirth, women may experience uterine prolapse due to being over-fatigued or engaging in physical labor too soon. Most women with mild symptoms show no clinical signs. As the symptoms worsen, some women may feel a sense of heaviness in the lower abdomen, and this sensation intensifies when squatting or using the restroom, with a feeling of heaviness in the vulva. Some women may feel something protruding from the vagina, which can be retracted back into the vagina when lying flat; this is uterine prolapse after childbirth. Typically, this condition can be improved by performing anal contraction exercises.

The main causes of uterine prolapse

The causes of uterine prolapse in women are complex, with the most common being pregnancy and childbirth, especially multiple childbirths, which can lead to damage to a woman's pelvic floor muscles. Some women experience this during vaginal delivery using instruments such as forceps or vacuum extractors, which can injure the pelvic muscles and lead to uterine prolapse. Some women may engage in heavy physical labor too soon after childbirth before their pelvic floor functions have recovered, affecting the recovery of pelvic tissue tension and leading to uterine prolapse. Additionally, uterine prolapse may also occur in women who are overweight, suffer from internal medical conditions such as chronic cough, ascites, or constipation, which increase the pressure inside the abdominal cavity.

Can uterine prolapse be seen with the naked eye?

Uterine prolapse occurs when the uterus descends from its normal position, falling along the vaginal opening and moving out of its normal location, with the cervix or the entire uterus reaching or completely coming out of the vaginal opening. The main causes of uterine prolapse are childbirth injuries, prolonged increased abdominal pressure, and poor development of pelvic floor tissues. In mild cases of uterine prolapse, patients mostly do not have any symptoms and the condition is only identified during a gynecological examination. However, in severe cases of uterine prolapse, patients feel a mass coming out of the vaginal opening while walking, working, or squatting, and in serious cases, the entire uterus can completely prolapse out of the vaginal opening, becoming visible to the naked eye.

Can an ultrasound detect uterine prolapse?

Uterine prolapse cannot be detected through an ultrasound, because during the ultrasound when it is necessary to hold urine, the uterus is lifted, so the degree and severity of uterine prolapse cannot be determined by this method. Uterine prolapse can be diagnosed by a gynecologist's examination, which can also determine the severity of the prolapse. Treatment methods should be determined based on the severity of the prolapse and the symptoms of the patient. Mild uterine prolapse might recover through treating the underlying disease and exercising. However, uterine prolapse of second degree or higher must be treated surgically to be restored to the normal position.
