Morning sickness refers to the nausea and vomiting that some women experience during pregnancy. Considered a misnomer, because morning sickness can strike anytime of the day or night, and sometimes lasting all day. But, according to research having morning sickness may be a good thing for your baby. Today.com reported on August 4, 2014 that findings of this common sickness in pregnancy showed women were less likely to have a miscarriage or premature birth. And to top it all, babies born to women with morning sickness had fewer birth defects and scored higher on IQ tests later in life.
Most women suffer from some sort of morning sickness during their pregnancy and this is common due to the rising levels of the hCG (human chorionic genadotopin) hormone in your system coming from the placenta. The hCG is produced after implantation takes place and continues to increase until the 12th week of pregnancy, at which point the levels begin to decrease. Others believe that morning sickness is caused by progesterone; the dominant hormone during pregnancy. This hormone relaxes the muscles of the stomach, hence slowing down digestive processes and the emptying of the stomach, which leads to stomach acid.
The nausea can start as early as four weeks and usually tapers off around thirteen weeks as you start your second trimester, although some queasiness can linger somewhat throughout the term.
All in all, this new research from Dr. Gideon Koren, pediatrician at The Hospital for Sick Children in Toronto and founder of the Motherisk Program, states that the higher levels of these hormones equate to a brighter outcome for the fetus and decreases some of the risk factors in early pregnancy. This doesn't mean that if you don't have morning sickness, that you and your baby are in trouble -- this message is just to help mothers who are plagued with the ill effects of nausea that this research is a good thing and quite protective.
