According to a statement from the palace, the queen spent the night in the hospital on October 20 and is now on the mend.

"Following doctors' advice to rest for a few days, the Queen (opens in new tab) attended the hospital on Wednesday afternoon for preliminary tests and returned to Windsor Castle at noon today.

No further details are available, but it appears that Her Majesty the Queen (opens in new tab) returned to work directly after returning from the hospital.

The news comes after the 95-year-old monarch was forced to cancel a visit to Northern Ireland on the same day.

"The Queen has reluctantly accepted medical advice to remain at rest for the next few days. Her Majesty the Queen is in good health and regrets that she is unable to make her planned visit to Northern Ireland today and tomorrow."

The Queen's health will be in good shape when she celebrates 70 years (!) on the throne. and her health is of paramount importance in the run-up to her Platinum Jubilee next June, when she will celebrate 70 years (!) on the throne. For this reason, the Queen's doctors have long advised her to refrain from drinking alcohol until then, except on special occasions. The queen has been told to stop drinking in the evening, when she usually has a martini," a family friend told Vanity Fair magazine (opens in new tab)." It's not a big deal for the queen. She's not a heavy drinker, but it seems a bit unfair that at this stage of life she should have to give up one of her few pleasures."
