Catherine, Princess of Wales is in hospital after undergoing abdominal surgery.
The 42-year-old royal was admitted to The London Clinic in the UK capital on Tuesday for a planned operation which was deemed "successful" by doctors and she is expected to remain under the care of medics for up to two weeks before returning home.
She has cancelled all of her upcoming engagements and is not expected to return to her public duties until after Easter.
A statement from Kensington Palace explained: "Her Royal Highness The Princess of Wales was admitted to The London Clinic yesterday for planned abdominal surgery.
"The surgery was successful and it is expected that she will remain in hospital for 10 to 14 days, before returning home to continue her recovery. Based on the current medical advice, she is unlikely to return to public duties until after Easter."
No more details about Catherine's medical condition have been disclosed.
The statement added: "The Princess of Wales appreciates the interest this statement will generate. She hopes that the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private.
“Kensington Palace will, therefore, only provide updates on Her Royal Highness’ progress when there is significant new information to share."
The statement concluded by passing on the Princess' apologies to all those affected by the cancellation of her royal engagements.
It went to add: "The Princess of Wales wishes to apologise to all those concerned for the fact that she has to postpone her upcoming engagements. She looks forward to reinstating as many as possible, as soon as possible."
