Yaz Side Effect: As every woman who delivers a child knows, labor and delivery subject the body to forces that are not encountered in any other circumstance. The muscles and nerves in the pelvis are especially affected. As the baby’s head comes down into die pelvis, it presses against the muscles that line the inside of die pelvis. The farther down the baby’s head goes into the pelvis, the greater is the pressure against these muscles and underlying nerves. After the cervix is totally dilated, the pushing phase of labor begins. The mother is usually asked to wait for a contraction to start, then hold her breath and bear down as hard as she can in order to push the baby out. This bearing down presses the baby’s head against the mother’s muscles and nerves to such an extent tiiat the normal flow of blood is cut off temporarily, until that push is over. Without a fresh supply of blood, the tissues are deprived of oxygen and nutrition, making them more susceptible to damage. The pressures generated by pushing are three times as high as the tissues would normally tolerate for any prolonged time. However, the few minutes of rest in between contractions usually lets blood flow back to the area. This fresh blood carries oxygen and nutrition to the muscles and nerves and carries carbon dioxide and waste materials away. The several minutes between contractions are normally enough for die tissue to recover.
However, unless delivery occurs quickly, the baby’s head continues to press against the tissues with each contraction. For some women this pressure can cumulatively add up to many hours. Two nerves, called the pudendal and the pelvic nerves, lie on each side of the birth canal witiiin the muscles that are direcdy under the baby’s head. Because they are so close to the baby’s head, these nerves are especially vulnerable to the pressures of labor. The pudendal and pelvic nerves carry die signals from the brain to the muscles that hold the bladder and rectum in place.
Some recent studies show that the likelihood of incontinence and prolapse is lower if the mother (and her doctor) allows the natural force of the uterine contractions to push the baby down the birth canal, rather than the mother pushing as hard as she can during this time. Studies show that if the voluntary pushing part of labor can be limited to less than an hour, there is a lower incidence of injury to the nerves and muscles of the pelvis. This alternative may be a safer and more natural way to deliver. Let the uterus do the work it was designed to do.
