The rise in cesarean-section deliveries in recent years has been characterized by some as a key indication of the overmedicalization of childbirth. While the procedure undoubtedly saves lives and leads to better health outcomes for mothers and infants who face problems during pregnancy and labor, many experts say the procedure is being performed too often, and in many cases for nonmedical reasons, putting healthy women and babies at undue risk of complications of major surgery.
The rate of C-sections has reached more than 31% in the U.S., a historical high, according to 2007 data from the American College of Obstetricians and Gynecologists (ACOG). The reasons for the increase are many and have been widely discussed: the rising rate of multiple births, more obesity in pregnant women, the older age of women giving birth. In fact, C-sections have become so common that many women may have an inflated sense of safety about them. "For the most part, moms and babies go through the process healthy and come out healthy, so maybe there's this sense that we're invincible," says Dr. Caroline Signore of the Eunice Kennedy Shriver National Institute for Child Health and Human Development.

But C-section carries all the attendant risks of major surgery; and data show that compared with vaginal birth, cesarean delivery increases the odds that a mother will end up back in the hospital after birth with complications such as bleeding or blood clots.
Now obstetrics experts are actively seeking ways to drive down the number of C-sections. On July 21, the ACOG issued new guidelines recommending that hospitals allow most mothers who desire vaginal birth after cesarean, or VBAC, to attempt a trial of labor, including some mothers who are carrying twins or have had two prior C-sections. Despite studies showing VBAC to be safe for most women — ACOG data suggests that 60% to 80% of women who attempt VBAC will succeed — many hospitals have urged women to undergo a repeat cesarean over the past decade, largely to avoid medical risks and malpractice suits.
