'The Hidden Mothers' sheds light on the reality of Hyperemesis Gravidarum in pregnancy

Hyperemesis Gravidarum (HG) is a severe pregnancy illness affecting women of all ages and backgrounds. A new exhibition, linked to King’s research, platforms the experiences of women who have suffered and want to make a difference.

People saw the physical toll of HG, but they did not understand the depth of its effect on my mental health – how I felt I couldn’t go on, the loneliness I had to endure and that I couldn’t see any light on the horizon. I felt like I was dying, I was a shell of myself, nothing more than skin and bones. Many days I didn’t have the energy to even speak. Every morning I would open my eyes and just wish this was not my reality.

Hyperemesis Gravidarum (HG), a debilitating pregnancy illness, has gone virtually unrecognised by the medical establishment despite an estimated 30,000 pregnant women suffering from it every year in the UK. HG, and the lack of clinical care provision, has resulted in terminations and has been associated with depression leading to suicide.

The Hidden Mothers, a new exhibition at Science Gallery London by photographer Clare Hughes, is linked to a project led by King’s College London and to Guy’s and St Thomas’ NHS Foundation Trust, which aims to ensure all Hyperemesis Gravidarum sufferers can access guideline-recommended care for the condition. The resulting research outcomes have driven impactful changes to the way in which HG is perceived and the care that women receive.

Lived Experience of HG

After experiencing HG in during her first pregnancy, Clare Hughes developed The Hidden Mothers with a group of women who had also lived with the illness. The result is a photographic exhibition, using the Victorian concept of a ‘hidden mother’ visual metaphor (a 19th century trend in infant photography which saw mothers concealed in fabric to hold their baby still for an extended period) for how its participants have felt during their pregnancies.

The replicated photographic creative act helped to distance participants from their experiences and provided a powerful cathartic perspective, while contributing to the message: we won’t be hidden anymore.

Black and white portrait photographs of each woman are also on display in the exhibition, accompanied by captions from participants sharing their experiences, ranging from dismissive behaviour from medical professionals to a severe decline in mental health, extreme dehydration, hospitalisation and PTSD.

The aim of the exhibition is to shed light on the severity of HG and promote greater awareness, prompt further research and healthcare policy adoption, so fewer women have to suffer in the future.

I feel frustrated that my HG symptoms were dismissed by some people (including healthcare professionals) and that the severe impact HG has on day-to-day life for sufferers and their families is so rarely understood. I am also sad that I had such a negative pregnancy experience each time.
