The number of women dying of complications related to pregnancy is higher than any other developed country.
As maternal deaths decrease worldwide, the United States has experienced an increase by 26 percent in maternal mortality.
One of the leading causes of these deaths is preeclampsia - a pregnancy condition that is related to high blood pressure and liver damage.
In the past two decades, preeclampsia in the US has increased by 25 percent, a study by The American Congress of Obstetricians and Gynecologists found.
