Pregnancy Article ReprintAs the uterus expands during pregnancy, the bladder and urethra are pushed out of their normal positions. This may also affect bladder control, especially when the growing uterus presses on the bladder.
Pregnancy complications and birth trauma may damage the nerves responsible for bladder control in women. Medical interventions such as episiotomies and forceps deliveries can also damage women's bladders or urethras, causing urinary incontinence.
Women should inform their doctors if bladder control difficulties continue after pregnancy, but urinary incontinence is often considered normal in the weeks after birth. If women continue to experience bladder control difficulties six weeks after pregnancy, treatment for urinary incontinence may be required.
Women may experience the effects of pregnancy-related urinary incontinence years after the actual pregnancy. Women in their forties or fifties may develop urinary incontinence that is traced back to pregnancy trauma.
Damage to bladder control nerves or the pelvic wall during pregnancy may not be immediately apparent. However, over time, the original damage slowly progresses, until women develop bladder control problems.
Kegel exercises are used to maintain pelvic floor muscle strength during pregnancy. In the study, 32 percent of the women practicing pelvic floor muscle exercises reported urinary incontinence 36 weeks into the pregnancy, compared to 48 percent of the women in the control group.
Three months after the end of pregnancy, only twenty percent of the women using pelvic muscle exercises reported urinary incontinence, as opposed to thirty percent of the control women. While more studies into the effects of pelvic floor exercises on pregnancy and bladder control are required, the study suggests that women may be able to minimize the effects of pregnancy on bladder control.
