Even mild stages of the disease can have an impact
In pregnant women, the risk of adverse pregnancy outcomes - such as premature birth or the need for neonatal intensive care - rose through the stages of chronic kidney disease.
The risk of death or intrauterine fetal malformations were not higher in women with chronic kidney disease.
An estimated 26 million people in the US have chronic kidney disease.
Even mild renal disease during pregnancy may increase some risks to mother and baby, according to a study published in a forthcoming issue of the Journal of the American Society of Nephrology (JASN). The results may be useful in guiding the board and prenatal care for women during pregnancy.
