Study Says Severe Morning Sickness Could Lead to Preterm Birth

By Lauren Jimeson |

I’ve suffered from morning sickness this entire pregnancy. My first trimester was the worst. Especially because I didn’t manage to gain any weight due to the constant sickness. I was sick with my first pregnancy for seven months and thought that it would subside around then with this pregnancy, however it did not.

Although I was never diagnosed with hyperemesis gravidarum, severe morning sickness that affects 1 percent of women, with either pregnancy, my inability to keep food down and the three medications that I had to take several times during the day, had me thinking I should have been.

My main concern when I was dealing with the morning sickness was the health and well being of my baby. Because it was so hard for me to keep my food down, I wanted to make sure she was getting the proper nutrition that she should. I didn’t want to harm her in any way.

A new study says that morning sickness that interferes with a pregnant woman’s ability to live, may be a warning sign that there might be complications later in pregnancy, including preterm birth and preeclampsia. 

The study, conducted by Alere Health, looked at data from 81,486 women enrolled in an Alere maternity education program who delivered between 2004 and 2011. Following their delivery, the women were asked how morning sickness affected their pregnancy and if it interfered with their daily lives.

The findings of the study showed that women who had severe morning sickness that interrupted their lives were 31 percent more likely to develop preeclampsia and 23 percent more likely to deliver their baby before 34 weeks compared to the pregnant woman who had little to mild morning sickness. Research still isn’t clear why severe morning sickness caused women to experience these effects, but many researchers think it could have something to do with lack of nutrition and weight gain during pregnancy.

Weight gain and lack of nutrition were always my doctor’s number one concern during my pregnancy. Fortunately we were able to find medications that gave me the ability to keep most of my food down. The medication had no harmful effects on my baby and I was able to give her the nutrients she needed to grow. At nearly 38 weeks, I can happily say that the findings in this study didn’t apply to me!

    I had severe morning sickness and I went to 41 weeks 3 days the first time and had to have a csection and the second time I went all the way to my csection date at 39 weeks 3 days…with no end in sight. Interesting

    Interesting article. I had moderate hyperemesis with my first and delivered early because of escalating blood pressure and protein in my urine (wasn’t officially diagnosed with preeclampsia). This time around I had severe hyperemesis (required a med pump and ivs) for the first 17-18 weeks. It will be interesting to see what happens as this pregnancy progresses. I am currently 23 weeks.
