event group [13,14] . The remaining seven studies did not find a difference between the two groups. However,
bariatric surgery reduces leptin, a hormone increased in maternal obesity that is noted to have a tocolytic
effect on the myometrium theorized to prolong labor and increase the likelihood of cesarean. Therefore,
post-bariatric women who are obese may produce less leptin resulting in better contractility compared to
the obese control.

Our analysis found there was a decreased incidence of cesarean sections in the bariatric surgical women
affected by obesity, as compared to the obese controls. We conclude that bariatric surgery lowers the rate of
cesarean deliveries.
