Information about Morning Sickness or NVP

Many pregnant women suffer from a very real medical condition known as “Nausea and Vomiting of Pregnancy“ or NVP, which is commonly referred to as morning sickness. Between 70% to 85% of pregnant women experience the discomforts of NVP.1

Although NVP is often referred to as morning sickness, only about 14% of women experience symptoms that occur just in the morning and 58% of pregnant women experience symptoms throughout the day.3  NVP usually develops between the 4th and 6th week of pregnancy2.  In approximately 90% of cases, it stops by the 16th week, but in about 10% of cases, NVP continues beyond the 16th week.  Some women experiencing symptoms of NVP through their entire pregnancy. 

The extreme end of the spectrum of NVP, called hyperemesis gravidarum, can cause significant weight loss and can lead to dehydration requiring hospitalization for IV fluid management. The percentage of pregnant women who experience hyperemesis gravidarum ranges from 0.5% to 2%.1

While the vomiting, retching, and nausea can be very distressing, morning sickness can also dramatically affect a pregnant woman’s home life, relationships, work schedule, and emotional well-being. Numerous studies have documented the significant impact morning sickness can have on the lives of pregnant women.
