The symptoms of nausea and vomiting in pregnancy were described by 363 pregnant women who kept daily symptom diaries. All delivered a single live baby. The majority of information collected was prospective, with the median day from last menstrual period to initial interview by the study midwife being day 57. ⋯ Among the study population, 206 women were in paid employment. Seventy three of these women (35%) spent a mean of 62 hours away from their paid work because of symptoms of nausea and vomiting, showing the socioeconomic significance of this condition. The detailed information gathered should help in the investigation of the aetiology of nausea and vomiting during pregnancy.
