RCOG statement in response to the Duke and Duchess of Cambridge expecting their third child

News 4 September 2017

Dr Manjeet Shehmar, Consultant Obstetrician and Spokesperson for the Royal College of Obstetricians and Gynaecologists, says:

“We are delighted to hear that the Duke and Duchess of Cambridge are expecting their third child.

“Kensington Palace has confirmed that the Duchess is suffering from hyperemesis gravidarum, commonly known as severe morning sickness, a condition that she experienced during her first two pregnancies.

“Severe vomiting in pregnancy is more common, but the rare Hyperemesis gravidarum is a potentially serious condition that is characterised by severe and prolonged nausea and vomiting. It can lead to dehydration and significant weight loss. If treated effectively, the condition is unlikely to harm mother and baby.

“We wish the Duchess well with her pregnancy.”
