According to scientists, extreme morning sickness are linked to your genes, whilst they also think that it may be possible to treat the condition.
It is estimated that between one in 300 and one in 50, women suffer from hyperemesis gravidarum, which causes severe nausea during pregnancy. The Duchess of Cambridge also suffered from this during her pregnancy and like her, some cases of repeated vomiting during pregnancy can result in being hospitalised.
After losing a baby to hyperemesis gravidarum in 1999, Marlena Fejzo, from the University of California Los Angeles has been researching the condition. In her latest study which was published in the journal Nature Communications, she has tried to identify the common genetic factors in women with the condition.
The study by Professor Fejzo and her colleagues showed that proteins made by two particular genes were usually high in women suffering from hyperemesis gravidarum. Investigating and finding a way to reduce the protein levels could lead to the reduction of nausea.
Professor Fejzo said, “A treatment could make a huge difference for them. It is severe enough that many women decide not to have more children because of this.”
