Study Finds Link Between Morning Sickness, Likelihood of Healthy Pregnancy

Women's Health Update

A new study has found a strong connection between nausea and vomiting during early pregnancy and a lower risk of miscarriage.

JAMA Internal Medicine reported about the study done by researchers at the National Institutes of Health’s (NIH) Eunice Kennedy Shriver National Institute of Child Health and Human Development and other institutions.

Many pregnant women experience morning sickness, with includes nausea and vomiting, especially during their first trimester, according to the NIH. Morning sickness symptoms usually go away by the 14th to 16th week of pregnancy.

Though there is no specific known cause for morning sickness, it is commonly thought that it is caused by the increased hormones in the body in early pregnancy. 

This new research proposes that morning sickness protects the growing fetus from toxins and disease-causing organisms in food and drinks, according to the NIH.

In the study, 797 women with positive pregnancy tests participated, and 188 of those pregnancies ended in miscarriage, according to the NIH. By week eight, about 57 percent of the women had nausea and almost 27 percent had nausea and vomiting. 

The study found that these women were 50 percent to 75 percent less likely to miscarry compared to those with no nausea or nausea and vomiting.

Though this study found a link between morning sickness and a thriving pregnancy, that doesn’t mean that women without morning sickness cannot have healthy pregnancies and births. Many women have completely healthy pregnancies and births without any symptoms of morning sickness.
