Buckingham Palace has revealed that the Queen is being monitored by medics at Balmoral after they started to worry about her health.
"Following further evaluation this morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision," they said in a statement.
"The Queen remains comfortable and at Balmoral."
Her immediate family has been informed.
The statement comes after the Queen, 96, left a fictitious Privy Council meeting on Wednesday because her physicians had advised her to take it easy.
This isn't the first time the the ruling sovereign is having health issues this year.
In June this year, the monarch had to opt out of several of her Platinum Jubilee celebrations in June 2022, including the Thanksgiving Service and the "Party At the Palace" concert.
Just three months earlier, the monarch had also gotten a bout of COVID-19.
The royal matriarch was "experiencing mild cold-like symptoms," according to Buckingham Palace, in February 2022, but she would still be performing "light tasks at Windsor" while she healed.
The statement said, "She will continue to receive medical care and follow recommendations.
The queen briefly discussed her experience coping with the coronavirus during a teleconference with the Royal Hospital personnel in London in April 2022.
“It does leave one feeling very tired and exhausted doesn’t it, this horrible pandemic."
Prince Charles himself opened up on his mother's health late last year after she had been forced to cancel her appearance at the annual Remembrance Day celebration.
“She’s alright, thank you very much. Once you get to 95, it’s not quite as easy as it used to be. … It’s bad enough at 73,” the Prince of Wales told Sky News.
Despite the illnesses, the queen was still of the mind to keep working, something that caused much concern among those close to her.
“The Queen has been advised by her loved ones and trusted advisors to go a lot easier on herself, even if it means missing more functions than she would like,” Us was told in May 2022.
