Do You Have Morning Sickness? It’s a Good Sign for the Baby

Morning sickness is known as a common pregnancy symptom and considered a terrible experience, but it’s actually pointing to a healthy pregnancy in women.

morning-sicknessA new study has revealed that morning sickness may reduce the chances of miscarriage in women. It suggests that vomiting and nausea during pregnancy may help to protect the fetus against pollutants and disease-causing organism.

“It’s a common thought that nausea indicates a healthy pregnancy, but there was not a lot of high-quality evidence to support this belief,” said Stefanie N Hinkle, the study author from National Institute of Child Health and Human Development (NICHD), US.

“Our study evaluates symptoms from the earliest weeks of pregnancy, immediately after conception, and confirms that there is a protective association between nausea and vomiting and a lower risk of pregnancy loss,” added Hinkle.

The researchers examined data from the Effects of Aspirin in Gestation and Reproduction (EAGeR) trial and verified whether consuming low-dose aspirin daily helps to prevent miscarriage in women, who already had pregnancy losses.

They observed information collected from women participating in the study and who had a positive pregnancy test.

The pregnant women were asked to maintain a daily diary, which includes whether they experienced vomiting and nausea between the second to eighth weeks of pregnancy. Also, they had to answer the questionnaire related to their symptoms through the 36th week of pregnancy.

The study authors noted that prior studies on nausea and miscarriage were not able to get complete information on symptoms during the early stage of pregnancy.

Rather, most of the studies relied on the women’s reminiscence of symptoms after they had experienced a pregnancy loss.

In EAGeR trial, total 797 women had positive pregnancy tests, whereas 188 pregnancies ending in a loss. Through the eighth week of pregnancy, 57.3 percent women informed experiencing nausea and 26.6 percent reported nausea with vomiting.

At the end, researchers discovered that these women were at 50-75 percent lower risk to experience miscarriage than others who had not experienced nausea and vomiting.

The study has been published in the journal JAMA Internal Medicine.
