The Princess of Wales is being treated in hospital after undergoing successful abdominal surgery and is expected to remain there for up to two weeks, Kensington Palace has said. Catherine, 42, was admitted to the London Clinic on Tuesday for the planned procedure, but no further details were given. The palace said she wished her medical information to remain private. She is expected to stay at the private hospital for 10 to 14 days before returning home to continue her recovery, and is not expected to resume public duties until after Easter based on current medical advice, the palace said. A statement from the palace said: “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’s progress when there is significant new information to share. “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.” The palace refused to confirm what Catherine was being treated for, but confirmed that the condition was non-cancerous. There will now be no international travel for the prince and princess in the coming months. The Prince of Wales is expected to postpone a number of his engagements as he supports their three children, and it is understood he will not undertake official duties while his wife is in hospital or during the immediate period after her return home. Her parents, Carole and Michael Middleton, and her siblings, Pippa Matthews and James Middleton, are to support her recovery at the royal couple’s home in Windsor. When Catherine celebrated her birthday just over a week ago, the monarchy’s official social media accounts shared a new behind-the-scenes photo of her at the king’s coronation last year. She has seemingly enjoyed good health, but was admitted to hospital while pregnant after suffering from hyperemesis gravidarum – severe morning sickness. She is very physically active and is frequently seen participating in sporting activities during official royal engagements. Since marrying William in 2011 and becoming an HRH, she has carved out her charity work with a focus on mental health and early childhood. The couple are reportedly hands-on parents, regularly undertaking the school run. It is understood that one of them tries to be at home when the other is on an official engagement whenever possible. The number of official engagements they undertake has risen since they became Prince and Princess of Wales, and since the departure of the Duke and Duchess of Sussex as working royals. Catherine has often been described by royal observers as the monarchy’s safe pair of hands and as having a “keep calm and carry on” approach. Jamie Lowther-Pinkerton, who was private secretary to the Cambridges and the Duke of Sussex, and used to work for Queen Elizabeth the Queen Mother, told the Times: “She takes time to talk to people. She is tough. She has got that queen mother feel in her, so that when things need doing, she is there to do them.”
