We are currently the only charity in Ireland providing information and support to women with hyperemesis here, however, there are a number of excellent international resources you can access.
Pregnancy Sickness Support is our sister charity in the United Kingdom, including Northern Ireland. Their website hosts a mountain of information from oral hygiene to managing your mental health. They also have a forum on their website which women from Ireland are welcome to join.
The Hyperemesis Education and Research (HER) Foundation is the main charity in the United States which provides support and information internationally. They are the main funders of research into HG in the US and have volunteers around the globe. Their website hosts dozens of research papers and support information as well as a forum.
Spewing Mummy is a UK blog by the Chairperson of PSS, Caitlin Dean. It has a wealth of information in a straight talking and often witty style. Caitlin has written two books on hyperemesis. Hyperemesis Gravidarum - The Definitive Guide is for sufferers and healthcare staff. The second, How to be an HG Hero, is a book for children whose mother's are sick to help them understand and empower them.
