Morning sickness is a sign that pregnancy loss possibility is very low, according to a study by JAMA Internal Medicine.
Nausea and vomiting are very normal in a woman's body, which is more evident during emotional periods, study author Stefanie N. Hinkle, Ph.D. told CBS News. Hinkle is a staff scientist at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
Morning sickness does not necessarily happen in the morning as it disturbs a pregnant woman any time of the day. The study by JAMA Internal Medicine reveals that "for most women, nausea and vomiting subside by the 4th month of pregnancy. Others may have these symptoms for the duration of their pregnancies..." Although they still do not know exactly the cause of morning sickness, the possible answer according to them is that such sensation is a sign of protection for the fetus against toxins and disease-causing organisms that come from foods and beverages that the mom is taking into her body. Hinkle said that hormonal mechanisms might also be at play when the symptoms of morning sickness attack. Further research is needed to understand the underlying cause, the research team said.
In spite of the researchers suggesting that morning sickness is a good sign, pregnant moms should always be wary that vomiting, nausea and other symptoms can be brought by something else. It is then important to keep watch of the lifestyle factors like caffeine and stress, which are of significant effect on morning sickness symptoms.
Hinkle said that pregnant moms who do not experience morning sickness that much should not be alarmed. "Not all pregnancies are the same," she said. "Everyone's individual experience is different so just because you don't have symptoms does not mean that you're going to go on to have a loss," she added.
