Study finds that being pregnant with multiples makes moms more at risk of nausea and vomiting during pregnancy. But the risk of experiencing vomiting and nausea with twins are even greater if you carry at least one girl. That was the conclusion of a Japanese study published in the Journal of Epidemiology. Participants were enlisted from the Japan Environment and Children’s Study. 91,666 women were included in the study. Women pregnant with singletons and women pregnant with twins participated. The researchers looked at whether or not the women experienced nausea and vomiting in the first trimester of their pregnancies. They found that 82.7 percent of the women experienced some symptoms of nausea and vomiting during the first trimester. 11.1 percent experienced severe symptoms.

Expecting one or more girls put you more at risk

The researchers found that women expecting a singleton girl and women with twin pregnancies were more at risk of feeling nauseous and of vomiting compared to women expecting a boy and singleton pregnancies, respectively. They were also more at risk of experiencing severe symptoms. The researchers also looked solely at the twin pregnancy group. They found that nausea with twins and vomiting were reported more frequently when one or both infants were girls, compared to twin pregnancies where both infants were boys. That was also the case with severe symptoms. Based on these findings, the researchers concluded that a factor in the female baby during pregnancy associates with the severity of nausea and vomiting.
