Help HER - » HG Research | Genetics of HG | Overview

Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy. It is generally described as unrelenting, excessive pregnancy-related nausea and/or vomiting that prevents adequate intake of food and fluids. If severe and/or inadequately treated, it is typically associated with:

  • loss of greater than 5% of pre-pregnancy body weight (usually over 10%)
  • dehydration and production of ketones
  • nutritional deficiencies
  • metabolic imbalances
  • difficulty with daily activities

HG usually extends beyond the first trimester and may resolve by 21 weeks; however, it can last the entire pregnancy in less than half of these women. Complications of vomiting (e.g. gastric ulcers, esophageal bleeding, malnutrition, etc.) may also contribute to and worsen ongoing nausea.

The Hyperemesis Education & Research (HER) Foundation provides education & support for mothers suffering from hyperemesis gravidarum and those who care for them. Only those who experience HG can truly know how difficult it is! The HER Foundation is here to be a voice of support and education to all who are faced with managing HG.

Current 2007-2012 Study: Genetics of Hyperemesis Gravidarum (HG)

This study is designed to identify individuals affected with HG, to study epidemiologic factors via an online survey, to collect DNA samples from saliva through the mail at no cost or travel for you, and to search for genes and risk factors that may be potentially associated with this condition. To be eligible, you must have suffered from HG and had treatment for your HG that includes i.v. hydration, TPN or other form of non-oral feeding (ie nasogastric feeding), OR both, and are able to recruit a friend with at least 2 pregnancies who has NOT suffered from HG to serve as a control. If you live in the United States and are interested, please contact Marlena Schoenberg Fejzo, PhD at or 310-210-0802. Download the USC/UCLA Consent Form (804 Kb PDF) for more details about the study.

Once you have a study ID number, you can begin your survey here.

Identification of genes and risk factors that contribute to HG will lead to a better understanding of the causes of severe nausea and vomiting of pregnancy, and should be a first step toward the development of more effective treatments or a cure for this devastating disease.
