Hyperemesis Research

"Research on HG's short- and long-term effects is desperately needed and needed now. We need to do more to find a cure for this disease that has such devastating effects on a growing number of soon-to-be mothers."
- Congressman Xavier Becerra (CA)

Current Research

Currently the HER Foundation, in collaboration with UCLA and USC, is studying the Genetics of Hyperemesis Gravidarum (HG). These HG Researchers need your help regardless if you have had or have not had HG.

Why More Research Is Needed

Hyperemesis gravidarum (HG) was first recognized several centuries ago and was thought to be related to a physiological cause such as toxins, ulcerations, or infection. However, in the 20th century it was erroneously decided that HG was caused by psychological conflicts instead. Limited research and outdated theories have fostered this belief from generation to generation of health professionals, resulting in unnecessary suffering and financial loss for too many women and their families, not to mention unknown consequences for their unborn children.

Our Role in Research

The HER Foundation is a non-profit organization dedicated to educating others on the management of hyperemesis gravidarum (HG). It is our goal to increase awareness of available medical care and the potentially devastating consequences if untreated.
