HG Researchers need your help! 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.
More information, including contact information, at the Help HER website.
