It is estimated that 50 to 90 percent of women with normal pregnancies have some degree of nausea, with or without vomiting. The duration and severity of symptoms varies and can be classified as either morning sickness or hyperemesis gravidarum (HG).

Morning sickness — is mild nausea and vomiting that may occur at any time of the day or night due to pregnancy. It often develops around six weeks of gestation and may start to improve by 16-18 weeks. However, symptoms continue into the third trimester in 15 to 20 percent of women and until delivery in 5 percent of women.

Hyperemesis gravidarum — is more severe nausea and vomiting of pregnancy. Women with hyperemesis often vomit multiple times every day, are often unable to consume food and liquids, and may lose more than 5 percent of their prepregnancy body weight. Women with hyperemesis gravidarum often become dehydrated and may develop vitamin and other nutrient deficiencies over time if they are not treated. This condition typically requires evaluation in the hospital, IV hydration and treatment with medication(s).

Nausea and vomiting in pregnancy (NVP) can be mild to completely debilitating that some women are unable to work or function to take care of their other children. I always advocate, do what you can, to get through. However, understanding the risk factors and causes of NVP may help you seek earlier interventions to minimise symptoms and get you through. Knowing these ensures you can discuss testing and treatment options with your health care provider so you and your baby are well as can be.
