The British monarch was taken to King Edward VII’s Hospital in London after suffering from symptoms of gastroenteritis, said a palace spokesman.
The spokesman added a “decision was taken on medical advice to take her from Windsor (Castle) to hospital,” and that it was ”a precautionary measure.”
The Queen is expected to spend two days recuperating in the hospital from the flu-like symptoms; however, all of her official engagements have been either canceled or postponed, including a two-day trip to Italy on March 6-7.
At 86, the Queen Elizabeth has been in overall good health, and was last in the hospital in 2003 for a knee operation
