Q: What are the causes of vaginal loosening? A: First of all, pregnancy and vaginal delivery: during delivery, the fetal head enters the vagina and compresses the muscles and fascia of the pelvic floor and related supporting structures, and the ligaments of the uterus are also stretched very much, especially in the case of slow and uneventful labor, the prolonged pressure of the fetal head, coupled with the forceps or fetal head suction, etc., often cause the tearing of the muscles and fascia of the pelvic floor and related supporting ligaments. ligament damage. Secondly, as women age, their hormone level decreases, the pelvic floor muscles, fascia and related supporting structures degenerate, muscle tone decreases, fascia thins, and vaginal mucosa atrophies, exacerbating the looseness of the vagina. Third: Nutritional factors: Long-term chronic diseases, malnutrition, weight loss and dieting, and physical wasting lead to weakness of pelvic floor muscles, fascia and ligaments, which aggravate vaginal loosening. Fourth: long-term increase in abdominal pressure: such as asthma, constipation, pelvic and abdominal masses, etc.
