Nausea and vomiting of pregnancy (NVP), commonly referred to as "morning sickness", is a very common complaint for expectant mothers.  Approximately 70% of all pregnant women will experience nausea at some point during their pregnancy.  Additionally, up to 50% of women will also experience vomiting as a result of pregnancy.  As a result, up to 25% of employed pregnant mothers experiencing symptoms will end up missing work at some point during pregnancy.  Although nausea and vomiting of pregnancy is very common, few mothers are willing to take medications during pregnancy due to concerns about the possible impact of the medications on the developing fetus during embryogenesis.  There are legitimate reasons to avoid medications given the serious problems with Thalidomide in the past.  Also, pharmacological options can lead to unwelcome effects on the mother including drowsiness.  Therefore, many expectant mothers today are looking for natural and safe treatments to cure their morning sickness while not placing the fetus at risk.  

    Rarely, nausea and vomiting of pregnancy becomes severe with excessive vomiting, malnutrition, dehydration, and weight loss.  This is a called hyperemesis gravidarum and the patient should contact their physician as there may be an increased risk to the mother as well as the fetus.  Depending on its severity, hyperemesis gravidarum may require medications, hospitalization, and fluid resuscitation.  Tests will look for signs of dehydration, including a urinalysis, to check for ketones, as well as thyroid function.  

    This website is designed to provide information regarding current treatment options for morning sickness, clinical evidence of the benefits of such treatment options, and the safety of these options.  These opinions should not replace consultation with your physician.  It is important to talk with your physician prior to beginning any treatments or medications for morning sickness.
