About us
Built from lived experience. Designed to change systems.
The HG Collective is an independent systems-change organisation working to improve recognition, treatment and care across the spectrum of pregnancy sickness, with particular expertise in hyperemesis gravidarum.
Our purpose
Scientific progress is not enough if care does not change.
Pregnancy sickness is often minimised, despite its ability to affect nutrition, hydration, work, family life and emotional wellbeing. At the severe end of the spectrum, hyperemesis gravidarum is a serious, biologically driven pregnancy condition. Across that spectrum, recognition, access to treatment and the standard of care still vary considerably.
We bring together lived experience, research, healthcare expertise and policy advocacy to close the gap between what evidence and guidance say and what people with pregnancy sickness or HG actually receive.
Our focus is not simply on describing the problem. It is on improving the policies, pathways, standards and decisions that shape care.
The founding team
Different expertise. One purpose.
Charlotte Howden
Co-founder
Charlotte brings national leadership, policy advocacy and lived experience to The HG Collective. Her work has included developing services, educating healthcare professionals, contributing to research and policy conversations, and using public engagement and the media to challenge the way pregnancy sickness and HG are understood and treated.
Lindsay Salmon
Co-founder
Lindsay brings expertise in community engagement, counselling and education. Her work is shaped by lived experience of HG and by years spent building relationships, training professionals and strengthening support around people affected by pregnancy sickness and HG.
Tuesday Davies
Co-founder
Tuesday brings expertise in service design, volunteer management and operational improvement. She develops clearer systems and sustainable ways of working so that services are effective for both the people using them and the teams delivering them.
Our principles
Clear principles. Visible accountability.
Evidence-led
Claims, recommendations and standards should be traceable to credible evidence.
Lived-experience informed
The reality of pregnancy sickness and HG should shape systems without requiring people to repeatedly relive distressing experiences to establish legitimacy.
Collaborative
Meaningful change requires people affected by pregnancy sickness and HG, healthcare professionals, researchers and decision-makers to contribute to the same work.
Transparent
We are clear about our evidence, limitations, relationships and the progress still required.
Independent and built for public benefit.
The HG Collective is registered as a Community Interest Company. We exist to create public benefit by improving understanding, standards and systems of care across pregnancy sickness, with particular expertise in hyperemesis gravidarum.
