The Norwegian Research Council (NRC) has over the last decade had an increasing focus on women?s health in general. As a part of NRC's efforts, severe nausea and vomiting in pregnancy (hyperemesis gravidarum, HG) has been explored thoroughly using large N orwegian population based datasets. Although HG is the most common reason for hospitalisation during early pregnancy, it is an understudied disease where etiology and consequences remains a puzzle. HG often leads to undernutrion as well as malnutrition du ring first trimester, a time point where the fetus is particularly vulnerable to environmental changes. Metabolic disturbances in pregnancy taking place in women with HG might resemble those seen during starvation. "Hunger-studies" from the Netherlands, C hina and Biafra have shown that maternal starvation during early pregnancy is associated with change in the offspring's disease patterns, such as increased risks for cardiovascular disease, diabetes and the neurodevelopmental disease schizophrenia. This m akes research on HG larger than the disease itself, given the fact that a large proportion of all pregnancies globally take place in women exposed to under- and malnutrition.
