U.S. government scientists say more women will be giving birth by C-section for the foreseeable future. A new study by researchers with the National Institutes of Health found that nearly one-third of first-time moms delivered by cesarean, according to AP. That has consequences years later, since many doctors and hospitals follow a policy of «once a cesarean, always a cesarean.» The study also suggested a link between chemically induced labor and higher likelihood of a C-section. Women whose labor was induced were twice as likely to have a cesarean. C-sections account for about one-third of U.S births, and many medical experts think that's too high, providing little or no added benefit, while subjecting women to additional risks.
