Not Fun for Mom-to-Be, But Good for Baby
Morning sickness—nausea, sometimes with vomiting—is common in pregnancy, affecting more than half of women who are pregnant. While it certainly isn’t one of the most pleasant experiences associated with being pregnant, research shows it is a good sign for the unborn baby.
Morning sickness is not fully understood. It’s thought to be related, at least in part, to hormone changes during the first 12 weeks of pregnancy. It could be that nausea and vomiting evolved as a way to avert the expectant mother from foods that might carry risk—morning sickness usually peaks around the third month of pregnancy, which is when the fetus is most vulnerable to toxins.
A large study of 797 women who were pregnant showed that women who experienced morning sickness were 50 to 75 percent less likely to lose the pregnancy than those who didn’t. More research is needed, but it seems morning sickness is one sign of a healthy pregnancy, and may even provide some protection to the unborn baby.
