Study: Pregnant women with morning sickness less likely to miscarry

CHICAGO (WLS) -- It's an unpleasant side effect of pregnancy but a new study shows morning sickness may actually have a benefit.

Doctors found that women who experienced morning sickness were 50 to 75 percent less likely to experience pregnancy loss than women who did not have morning sickness, according to the study which was led by researchers at the National Institute of Child Health and Human Development.

Doctors said that confirmed there is a protective association between the two and that morning sickness is a sign of a healthy pregnancy.

Results were published Monday in JAMA Internal Medicine.

Morning sickness typically eases after the fourth month.
