Queen Elizabeth II stayed in the hospital for one night on Wednesday and was discharged the next day, but judging by the recent royal trip, the Queen has stayed in Windsor Castle as requested by the doctor and reduced the number of appearances.

Grandson Prince Harry was horrified by her hospitalization, and when Prince Philip, Duke of Edinburgh, died in April, Harry did not have time to see his grandfather for the last time because of a stiff relationship with the royal family (not long after oprah's interview aired), which he claimed in a documentary honoring the Duke of Edinburgh that it was his lifelong regret.
In order not to let regret happen again, or the death of his grandfather awakens Harry's remaining conscience, or worried about his and Meghan's future, Prince Harry is now very afraid and constantly confirming the queen's physical condition with the royal family.
A royal insider told US Weekly that Harry, 37, was horrified when he was told earlier this month that his grandmother was hospitalized in the UK.
Feeling very helpless at his home in Montecito, 5,000 miles away, he has been constantly "confirming" the Queen's condition with royal staff.
Harry currently lives in Los Angeles with his wife, Meghan, and his two children, Archie and Lilybert, and is the only member of the Queen's immediate family who does not live in the UK.
Sources say Harry will "never forgive himself" if he is unable to return to the UK before the Queen dies, as prince Philip said. Harry was far removed from his grandmother, which made him worry about what would happen after her grandmother's death.
The Duke of Edinburgh died in April of this year due to years of health problems, but Harry was in the United States at the time and was not able to return to the UK until after the death of his grandfather.
Although Harry attended Prince Philip's funeral with other members of the royal family, the inability to say goodbye to his grandfather before his death has always weighed heavily on Harry, the sources said.
They added that Harry "hopes to be able to go home with Megan for Christmas so that the Queen can meet her second daughter, Lily, and see Archie again." ”
It is understood that the Queen's situation is somewhat serious this time, except that she needs to rest according to the doctor's request, and she can only perform simple tasks at Windsor Castle.
Last week the Queen cancelled her royal visit to Northern Ireland and yesterday she was forced to "regretfully" cancel the opportunity to travel to Glasgow next Monday for the Cop26 climate summit, but she will speak to delegates via recorded video messages.
Royal assistants will scale back her schedule in the coming months, with senior royals such as Prince Charles and Prince William already gathering around the queen to support her, taking on greater responsibilities to ease her burden.
The Queen will now be accompanied by one of her children or grandchildren to all public events to avoid disappointment if she has to quit.
It can be said that the queen is the only person in the British royal family who is still tolerant of the words and deeds of the Harrys who continue to rub the royal family traffic.
She had turned a blind eye to their monetization of the title of Duke of Sussex, but that could change after the Queen's death.
According to the plan of the successor King Charles to streamline the monarchy, the Harrys may eventually be stripped of their royal titles, so the period before the Queen's death is a golden period for them to develop their personal careers, and Harry's panic may also contain a sense of not optimistic about the future situation.
