Treatment of hyperemesis gravidarum by electrostimulation of the vestibular apparatus

26 patients hospitalized with Hyperemesis Gravidarum were treated with electrical stimulation of the vestibular system, as the symptoms of Hyperemesis Gravidarum resemble the symptoms of motion sickness, where the electrical stimulation has been used successfully. The patients were treated for one hour daily, two hours before the standard infusion therapy. 89% reported a decrease in vomiting and nausea during the first application, 85% a lasting improvement. Theoretical considerations concerning the mechanism of the effect are discussed.
