Since it is not known which diseases are the so-called “four diseases”, it is not possible to judge whether they are accurate or not. The main causes of urinary leakage in women are physiological factors, as well as pathological factors such as prolapse of the female pelvic organs and hysterectomy. 1. Physiological factors: usually for pregnant women, the gradual increase of the uterus will lead to bladder compression and changes in hormone levels during pregnancy, which will also cause urinary leakage; there is also the possibility that during childbirth, the function of the muscles that control the bladder will decline, and the bladder nerves and other tissues will be damaged, which will lead to bladder and uterine prolapse and cause urinary leakage. 2. Prolapse of female pelvic organs: this usually causes the prolapsed organs to press on the urethra, or causes excessive displacement of the urethra, which changes the normal pelvic floor structure, affecting the bladder’s function of storing and excreting urine, and therefore causing urinary leakage. 3. Hysterectomy: If a woman has previously had malignant diseases such as uterine cancer, cervical cancer, etc., and thus had her uterus removed; the ligaments and muscles that the uterus and the bladder use together may be damaged, thus urine leakage may occur. Female urinary leakage may also be caused by other factors, it is recommended that the patient go to the regular hospital in time, under the guidance of the doctor to clarify the cause of the disease and then treat it, in order to achieve early recovery.
