Queen leaves hospital after gastroenteritis treatment Link to video: Queen leaves hospital following stomach complaint The Queen left hospital on Monday afternoon after being treated for symptoms of gastroenteritis. The 86-year-old was admitted to King Edward VII hospital in central London on Sunday as a precaution. She had been expected to stay in hospital for two days. She has cancelled her engagements this week, including a two-day trip to Rome and a visit to HMS Lancaster in London, but is reportedly in "good spirits." Buckingham Palace revealed details of the illness on Friday, when the Queen was said to be resting at Windsor Castle. She was forced to cancel a St David's Day engagement in Swansea on Saturday. As she struggled to recover from the stomach and bowel bug, the decision was made to admit her to hospital. She was driven by private car to the hospital in Marylebone. The Queen was well enough on Sunday to meet an employee privately to award her a medal for long service before travelling to the hospital. A palace spokesman said she was otherwise in "good health." The King Edward VII hospital, which is the preferred hospital for the royal family, was at the centre of a media storm in December when the Duchess of Cambridge was admitted with a severe form of morning sickness. Three days later one of the nurses who was hoaxed, Jacintha Saldanha, was found hanged at her accommodation.
