How common is nausea and vomiting of pregnancy?
Nausea and vomiting of pregnancy is a very common condition. Although nausea and vomiting of pregnancy often is called “morning sickness,” it can occur at any time of the day. Nausea and vomiting of pregnancy usually is not harmful to the developing baby, but it can have a serious effect on your life, including your ability to work or do your normal daily activities.
When does nausea and vomiting of pregnancy start?
Nausea and vomiting of pregnancy usually starts before 9 weeks of pregnancy. For most women, it goes away by the second trimester (14 weeks of pregnancy). For some women, it lasts for several weeks or months. For a few women, it lasts throughout the entire pregnancy.
What is the difference between mild and severe nausea and vomiting of pregnancy?
Some women feel nauseated for a short time each day and may vomit once or twice. This usually is defined as mild nausea and vomiting of pregnancy. In more severe cases, nausea lasts several hours each day and vomiting occurs more frequently. Deciding to seek treatment depends on how much nausea and vomiting of pregnancy affects your life and causes you concern, not whether your condition is “mild” or “severe.”
What is hyperemesis gravidarum?
Hyperemesis gravidarum is the most severe form of nausea and vomiting of pregnancy. It occurs in up to 3% of pregnancies. This condition may be diagnosed when a woman has lost 5% of her pre-pregnancy weight and has other problems related to dehydration (loss of body fluids). Women with hyperemesis gravidarum need treatment to stop their vomiting and restore body fluids. Sometimes treatment in a hospital is needed.
