It is widely accepted that morning sickness is a part of a healthy pregnancy, and inevitable for just about every woman at least within the first trimester. So does this mean that a lack of morning sickness is a sign of an ‘unhealthy’ pregnancy? Not necessarily. Many woman go on to have healthy babies despite having little or no morning sickness. Similarly having very severe and prolonged morning sickness can in fact be dangerous for both mother and baby.
It appears that morning sickness is a result of the rising hormone levels associated with pregnancy, like HCG (human chorionic gonadotropin) and estrogen. Since these hormone levels drastically rise during the course of pregnancy, especially in the first trimester, then it is assumed that the typical nausea and vomiting should be present in pregnancy. Unfortunately the process is not always as simple and the reason why morning sickness may not be present in some women is not always clear.
Main symptom of pregnancy?
There is no hard and fast rule when it comes to morning sickness. There have been studies that showed some correlation between mild to no morning sickness and low birth weight or preterm births. However, you should not be overly concerned if you do go through your pregnancy without the expected nausea and vomiting. Many women who find out about their pregnancy after 10 weeks often had no morning sickness at the outset yet go on to have healthy full-term babies.
The problem comes in when women depend entirely on the presence of absence of morning sickness as an indicator of pregnancy. Morning sickness is not a reliable symptom. Missed periods, changes in vaginal discharge, breast tenderness and so on are equally important symptoms of pregnancy even if there is no nausea and vomiting. A pregnancy test should therefore be done the moment any of these symptoms arise as the sooner a pregnancy is confirmed, the earlier a mother can make the necessary dietary and lifestyle changes for a healthy pregnancy.
Should you be concerned?
There is no reason to be unduly concerned about the lack of morning sickness provided that you have been consulting with a doctor, have regular prenatal checkups and all other indications are that you having a healthy pregnancy. In fact the lack of morning sickness is a blessing in many ways. Some are obvious, like not having to be running to the toilet several times a morning to vomit and being able to eat as normal. Others are less so – severe morning sickness has to be treated with drugs and some of these drugs may be harmful to the unborn baby.
Pregnant women who are not experiencing morning sickness should therefore not be overly fixated on this issue. Rather get proper medical advice from an obstetrician-gynecologist. Do not assume that the lack of morning sickness is a sure sign of a low birth weight, preterm birth or other abnormalities. The undue psychological stress in pregnancy can often be detrimental. Rather focus on all the other aspect of life and health that needs attention with the upcoming arrival of a baby.
