Nausea and vomiting in late pregnancy.

Nausea and vomiting in late pregnancy is a little-studied phenomenon. In this study of 116 midwestern women, 32% of the women had nausea and vomiting after 20 weeks gestation. The purpose of this study was to examine demographic, anthropometric, maternal health factors, and pregnancy outcomes in women who had late nausea and vomiting in pregnancy (NVP) and those that did not. Women who experienced late NVP had significantly higher parity, were older, gained less weight in pregnancy, and slept fewer hours per night than women who did not experience late NVP. By being aware of prenatal factors that may affect nausea and vomiting in late pregnancy, health care providers will be better able to maximize the quality of life for these women.
