"People are suffering, we're losing babies, we're losing mums: this is serious and we need to be taken seriously."
Photographer Clare Hughes, who suffered from hyperemesis gravidarum (HG) during her pregnancy in 2017, is speaking at the launch of her Hidden Mothers exhibition featuring portraits by expectant women.
Between one and three in 100 pregnancies are thought to be affected by HG, which can cause extreme pregnancy sickness, threaten the life of the foetus and require intravenous fluids in hospital to prevent dehydration.
"I wanted use my creativity, my photography, to make sense of what had happened to me during pregnancy," Ms Hughes says.
