Hyperemesis gravidarum: epidemiologic features, complications and outcome Academic Article uri icon


  • During the period of 4 years between 1985 and 1988, 190 patients suffering from hyperemesis gravidarum (HG) were hospitalized at the Soroka Medical Center. From the 190 patients, 164 were followed up throughout their pregnancies and delivered at our Medical Center. The epidemiology of HG as well as the incidence of maternal complications and pregnancy outcome were analyzed and compared with 209 controls. The incidence of HG in our patient population was 6.3/1000 live births. The patients in the study group had fewer pregnancies and deliveries and more spontaneous abortions in the past than in the control population. Premature contractions and vaginal bleeding during the first trimester were more common among women with HG. Other complications of pregnancy were no more common than among controls. Women with HG in their current pregnancy had a lower incidence of spontaneous abortions (3.1%) as compared with previously reported rates in the general population (15%). Perinatal outcome was no different in women with HG than in the controls. Women with severe HG did not have statistically significant differences in the incidence of pregnancy complications and their pregnancy outcome was the same as in those without severe HG.
