A Nerve Stimulator May Help Relieve Nausea And Vomiting In Pregnancy

A low-tech, nerve-stimulating wrist device appears to give pregnant women relief from nausea and vomiting during the first trimester, according to a study in the July issue of Obstetrics & Gynecology.
Nausea and vomiting are common during pregnancy and affect about 70 percent of all pregnant women during the first trimester.

Researchers studied 187 women from four states who were between 6 and 12 weeks pregnant. All of the women reported nausea and vomiting. Half of the women were randomized to receive the ReliefBand, a battery-powered watch-like device with two metal electrodes that stimulate the median nerve on the underside of the wrist. The other half received a similar-looking sham device.

Over a three-week period, the women who used the ReliefBand reported a significantly greater reduction in episodes and severity of nausea and vomiting than did the control group. Compared to the control group, the women who used the ReliefBand also gained more weight and had fewer episodes of severe dehydration.PregnancyAndBaby.com
