Royal fans often speculate about what caused King Charles' famous swollen hands. The monarch himself joked about his "sausage fingers" after getting off a long-haul flight to Australia in 2012.
A doctor has offered an insight into the potential cause of the 74-year-old's bulging digits, reports the Mirror. According to GP Chun Tang, Medical Director at Pall Mall Medical in Manchester, there are many reasons why this happens.
Dr Tang told the Daily Mail: "Often puffy fingers are a symptom of water retention which can be caused by numerous health conditions.

"This condition arises due to inflammation and can be a result of arthritis, multiple bacterial infections or even TB.
"Other possibilities include high salt levels, allergic reactions, medicinal side effects, injury and autoimmune disease."
'Sausage fingers' are called dactylitis in the medical world, causing severe swelling that affects your fingers and toes.
The King's Coronation this weekend was watched by millions of people around the world. He enjoyed a moving Coronation concert which he loved so much that he even took to his feet to dance alongside the Queen as they got carried away to the music of Lionel Richie, Katy Perry and Take That.
But lots of viewers were left wondering who the lucky guests were who were invited into the royal's special box to watch the music. Patricia Janet Scotland, Baroness Scotland of Asthal, was pictured next to our king dancing along to the music.
She is a British diplomat, barrister and politician, serving as the sixth secretary-general of the Commonwealth of Nations. Prime Minister Rishi Sunak and his wife were sitting right behind them.
Several royals, including the Wales children and their aunt and uncle Zara and Mike Tindall, were also in the box and danced throughout the incredible performances.
Lots of people posted videos of the royals dancing on social media. In one clip, King Charle's granddaughter Princess Charlotte is seen moving along to Katy Perry as her brother, Prince George, and mother Kate, the Princess of Wales, sit to her left and right.
