The main causes of uterine prolapse include pregnancy, childbirth injury to the pelvic floor muscles, long-term increase in abdominal pressure, such as chronic coughing, habitual constipation, and difficulty defecating. Prolonged heavy lifting. Long periods of squatting or standing, large pelvic tumors causing downward displacement of the uterus, or poor development of pelvic floor tissues and degenerative changes accompanied by prolapse of other organs. In menopausal women, due to the decline in sex hormone levels, the pelvic floor tissues may atrophy and degenerate, which can also lead to uterine prolapse or exacerbate its severity.
