The daughters of women who suffered from a tyrannical conduct of morning sickness are three times more likely to be plagued by it themselves, Norwegian researchers report. This stamp of morning sickness, called hyperemesis gravidarum, involves nausea and vomiting beginning before the 22nd week of gestation. In autocratic cases, it can actress to weight loss.

The condition occurs in up to 2 percent of pregnancies and is a common cause of hospitalization for in a family way women.

According to Vikanes, hyperemesis gravidarum was once thought to be caused by philosophic issues, "such as an unconscious rejection of the child or partner". But her team wanted to get a load of if genetics was actually the culprit. For the study, Vikanes's team collected material on 2,3 million births from 1967 to 2006.
