The most common causes of uterine prolapse can be categorized into three types.

The first type is childbirth injury, which is the main cause of uterine prolapse. During childbirth, especially with vaginal surgical assistance or prolonged second stage of labor, uterine prolapse can occur.

The second cause is long-term increased intra-abdominal pressure, such as chronic coughing, habitual constipation, prolonged standing, or weightlifting. These factors can contribute to uterine prolapse.

The third type involves poor development or degenerative changes in the pelvic tissues. This mainly refers to uterine prolapse due to congenital deficiencies in pelvic floor development. Generally, childbirth injuries are the most common cause.
