Morning Sickness

Fact Checked

Morning sickness is a very common pregnancy symptom that pertains to nausea with or without vomiting. Most pregnant women will experience some form of nausea from as early as the first month of their pregnancy and an approximate one third of all cases will experience vomiting. Morning sickness usually ends through the 14th to 16th week (3rd or 4th month) but may linger throughout the pregnancy. Moreover, the amount of morning sickness experienced during one pregnancy does not necessarily correlate to morning sickness in future pregnancies. It is generally true for nausea and vomiting to worsen pregnancies with twins or triplets.

There is generally no need to be concerned over the baby’s health if one has morning sickness. It does not affect the growing baby’s health unless there is severe morning sickness, also called hyperemesis gravidarum. Other than that, mild to moderate symptoms are not harmful to the baby. Slight weight loss may also be considered in cases of moderate morning sickness.Contrary to belief, it may occur at any time of the day, thus its name morning sickness is a misnomer.
