Question:
My husband has suggested that my hyperemesis may be due to a malformation with the fetus. Is there a correlation between hyperemesis that lasts throughout the pregnancy and birth defects?
Answer:
You and your husband can rest assured that nausea and vomiting of pregnancy, which affects 50% to 80% of all pregnant women, as well as hyperemesis (its severe form), are not the predictors of a malformed fetus. On the contrary, some studies have shown that NVP is the sign of a strong, healthy pregnancy and has a protective effect, provided that the diagnosis of hyperemesis has indeed been attributed solely to the pregnancy and no other possible diagnosis.
