Necessary. During pregnancy, as the uterus enlarges, it compresses the pelvic floor. Combined with injuries to the pelvic floor during a vaginal birth, this can lead to pelvic floor dysfunction, which increases the risk of conditions like uterine prolapse, bladder prolapse, and urinary incontinence. The more childbirths a woman has, the more severe urinary incontinence may become. Postpartum urinary incontinence can be improved through adequate rest and adjunctive therapies. 1. Adequate rest by scheduling fixed times to urinate and increasing the frequency of urination can help reduce residual urine. 2. Performing Kegel exercises at home can help strengthen the sphincter muscles, helping to prevent further worsening of urinary incontinence. 3. If the above methods are ineffective, pelvic floor electrical stimulation therapy can be considered.
