Most of the urine leakage during pregnancy is caused by the weak pelvic floor tissues of the fetus and uterus compression, most of which will return to normal after delivery, while some may lead to uterine prolapse or increased risk of stress urinary incontinence in the long term, requiring postnatal rehabilitation. During pregnancy, the uterus gradually increases in size with the continuous development and enlargement of the fetus, and there is a certain degree of pressure on the pelvic floor tissues. In late pregnancy, the body prepares for the delivery of the fetus and increases the oxytocin in the body, which prolongs the uterine isthmus into the lower uterine segment, aggravating the pressure on the pelvic floor tissues, resulting in protruding of the anterior wall of the vagina and compression of the bladder, resulting in stress urinary incontinence, or urinary leakage. If urine leakage occurs, you can reduce the time of standing and rest in bed to reduce the frequency of urine leakage and reduce the degree of leakage. If the leakage occurs repeatedly, you can consult your doctor at the hospital or undergo other treatments. If urine leakage occurs after delivery, you can promptly perform pelvic floor muscle repair exercises or electrical stimulation to repair pelvic floor muscle tone.
