The findings highlight the importance of recognizing morning sickness and managing it.
About 50 to 60% of pregnant women experience some type of morning sickness during pregnancy but about 1% have a severe form called hyperemesis gravidarum which, in severe cases, can lead to malnutrition.
Fortunately, only a small number of pregnant women experience significant nausea and vomiting that lasts beyond 10 to 16 weeks of pregnancy. Women who do have such symptoms should discuss them with their doctors, who may be able to provide solutions.
While there are no drugs for pregnancy nausea and vomiting, many excellent therapies exist including hydration and nutrition supplements. A change of diet, such as eating six to seven small meals a day rather than three large meals, may also help.
According to a new study morning sickness might be an indicator of more serious later-pregnancy complications including premature birth
