Our objective was to survey obstetrician/gynecologists concerning their management of nausea and vomiting in pregnancy. We mailed a survey on nutrition during pregnancy to the 230 ACOG Fellows who are members of the Collaborative Ambulatory Research Network and to a control sample of 800 non-Network Fellows. Results presented here are for the questions concerning prevalence and management of pregnancy-induced nausea. A total of 488 surveys (47.4% response rate) were analyzed. Respondents reported that on average, 51.4% of patients complain of nausea during pregnancy, and 9.2% complain of severe or prolonged nausea with vomiting. Respondents reported that on average, 2.4% of patients require hospitalization because of hyperemesis gravidarum. Treatments recommended by a majority of respondents for moderate nausea were eating frequent small meals (95.5%), snacking on soda crackers (88.5%), avoiding strong odors (75.6%), taking a prescribed antiemetic (71.3%), taking ginger (51.8%), and eliminating iron supplements (50%). Women physicians were more likely to recommend ginger and less likely to prescribe an antiemetic. For severe and sustained nausea with vomiting, with additional symptoms such as dehydration or weight loss, intravenous hydration (88.7%) and antiemetics (74.0%) were the most common treatment options. Almost half (48.8%) of respondents would hospitalize such patients. We conclude that obstetrician/gynecologists appear to be knowledgeable concerning current opinion on managing nausea and vomiting of pregnancy. Improvements in the management of nausea during pregnancy are more likely to come from further research, not education of physicians.
