Nausea and vomiting in pregnancy.

Abstract

Prospective data on 86 pregnant women were analysed to investigate the relationship between the pregnancy symptoms of nausea and vomiting and various demographic, social and psychological factors. In contrast to previous research findings no significant differences were discovered along demographic or social dimensions between women reporting no nausea, mild nausea and severe nausea during the first trimester of pregnancy. Not surprisingly, those women experiencing severe nausea reported significantly more sleep disturbances, fatigue and irritability. Women having both nausea and vomiting during the first trimester, reported significantly more unplanned, undesired pregnancies and negative relationships with their own mothers, than first trimester groups experiencing nausea only or no symptoms. Finally, those with continuing nausea and vomiting in the third trimester, when compared with those having no symptoms, tended to have reported significantly more psychological/psychiatric problems in the first trimester and were significantly more negative in their assessment of their own maternal relationship.
