Re-examining the adaptive function of nausea and vomiting in pregnancy
Emily H Emmott
Abstract:Nausea and vomiting in pregnancy (NVP) has been proposed to have a prophylactic function. In this commentary, I re-examine NVP from an evolutionary perspective in light of new research on NVP. First, current evidence suggests that the observed characteristics of NVP does not align well with a prophylactic function. Further, NVP is typically associated with high costs for pregnant women, while moderate-to-severe NVP is associated with increased risks of poorer foetal/birth outcomes. In contrast, mild NVP limite… Show more
