HG Research
Historically underfunded and overlooked, research into Hyperemesis Gravidarum is finally gaining momentum — with growing interest in understanding and addressing this severe condition.
Current research opportunities & findings
In April 2025, PSS conduted a survey to determine the availability of the only drug licensed for use for Nausea & Vomiting in Pregnancy called Xonvea. Despite being mentioned as a treatment option in RCOG and NICE Guidelines, it remains a postcode lottery.

“Historically, HG was the leading cause of death in early pregnancy and although mortality is now rare for this condition, it is not unheard of.”
