So far, Buckingham Palace and official spokesman have kept the Queen’s health affairs under tight wraps, but the recent overnight stay in hospital was the Queen’s first for nearly a decade.

The last occasion where the monarch was seen to be hospitalised was in 2013, after she had developed gastroenteritis – a common condition that causes diarrhoea and vomiting.

However, the Queen’s most recent orders from the doctor do not tend to be related to anything specific, just a precautionary break from her “relentless schedule”.

She has also been advised to give up her daily tipple of martini and beloved hobby of horse riding after feeling some form of “discomfort”, according to reports.

Although there is no official indication the Queen is in ill health, the ageing process can be tough on the body.
