The 34-year-old has cancelled her working commitments for the time being due to health complications.
“As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum. Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today.”
Symptoms of Hyperemesis Gravidarum are severe nausea and vomiting. Kate was hospitalised due to the condition during her pregnancies with Prince George, 4, and Princess Charlotte, 2.
