Morning Sickness Could Be Genetic

Severe morning sickness, also known as hyperemesis gravidarum, sends approximately 60,000 pregnant women to hospitals each year. Marked by severe nausea and vomiting, the condition can endanger the lives of pregnant women and their unborn babies.

For women whose sisters, mothers and grandmothers experienced extreme morning sickness during pregnancy, the risk of hyperemesis gravidarum may be greater, according to the results of a new study published online in the American Journal of Obstetrics and Gynecology.

Researchers from UCLA and the University of Southern California examined both the maternal and paternal family histories of 650 women with hyperemesis gravidarum and discovered that the condition appears to be genetic. Women with sisters who suffered hyperemesis gravidarum during pregnancy may have a more than 17-fold risk of experiencing the debilitating condition themselves.

For women who are planning to become pregnant, it might be wise to ask sisters, mothers, and grandmothers whether they suffered severe morning sickness during their pregnancies. While you may not be able to avoid hyperemesis gravidarum, you’ll undoubtedly feel better if you’re prepared for the possibility that you’ll experience the condition.
