ST. LOUIS (KMOX) – A new study concludes there may be a benefit to morning sickness for pregnant women.
The National Institutes of Health found evidence that nausea and vomiting during pregnancy is associated with a lower risk of miscarriage. The study followed nearly 800 pregnant women who had had a previous miscarriage.
Dr. Van Dalton at St. Anthony’s Medical Center in Fenton says there are a couple of theories why nausea and vomiting might be good for the mother-to-be.
“[Researchers] think [nausea and vomiting is] an evolutionary advantage to change a pregnant person’s dietary intake in pregnancy to increase the consumption carbonous foods or to decrees the chance of women eating foods harmful to pregnancy,” Dalton says.
She also cites a theory claiming nausea, vomiting is a marker for a “viable placenta” and that the lack of symptoms means the placenta is failing.
But at the same time, Dalton says women who don’t have nausea and vomiting early in pregnancy should not conclude something is wrong. This study appears in the journal JAMA Internal Medicine.
