Prevalence and severity of nausea and vomiting of pregnancy and effect of vitamin supplementation.

Abstract

The relation between number of daily vomiting episodes and mean weight loss may serve as a clinical tool to assess the severity of nausea and vomiting in pregnancy and the success of anti-emetics and rehydration regimens. Further study is needed to elucidate the biologic basis of the observed association between vomiting and lack of multivitamin supplementation in early pregnancy.
