King George VI faced a number of health challenges throughout his life. One of the most well-known of these was his struggle with a stammer, which made public speaking difficult for him. He worked with speech therapists to overcome this issue, and made significant progress in his ability to communicate with the public. In addition to his stammer, King George VI also suffered from a number of other health problems. He was a heavy smoker, and developed lung cancer as a result. He underwent surgery to remove one of his lungs in 1951, and thereafter his health improved somewhat. The king also suffered from circulation problems, which caused him to experience numbness and pain in his legs. This was thought to be related to his heavy smoking, which had caused damage to his blood vessels. He underwent a number of surgeries to address this issue, but it continued to be a problem throughout his life.

Overall, King George VI's health was a significant concern for him and for those around him, and he faced a number of health challenges throughout his life. However, he remained committed to his duties as a monarch, and continued to work tirelessly to serve his country and his people despite his health issues. His dedication and sense of duty continue to be remembered and celebrated to this day.

King George VI's health began to decline significantly in the last years of his reign. As mentioned earlier, he had undergone surgery to remove one of his lungs in 1951, after developing lung cancer. While the surgery was initially successful, he continued to suffer from circulatory problems, which caused him to experience numbness and pain in his legs.

In 1952, the king's health took a turn for the worse. He developed an arterial blockage in his right leg, which led to a thrombosis and a subsequent pulmonary embolism. Despite treatment, his condition continued to deteriorate, and he ultimately passed away on February 6, 1952, at the age of 56.

The king's death was a significant blow to the nation, coming at a time when the country was still recovering from the devastation of World War II. His daughter, Princess Elizabeth, became Queen Elizabeth II upon his death, and was faced with the challenge of leading the nation through a period of significant change and transition.

In addition to the emotional impact of the king's death, his declining health had also had a significant impact on his reign. He had been forced to cut back on his public engagements due to his health issues, and had struggled to maintain his physical stamina and endurance. Nevertheless, he continued to work tirelessly to fulfill his duties as a monarch, and remained committed to his role until the very end. His legacy as a dedicated and devoted monarch continues to be remembered and celebrated to this day.

King George VI's last days were marked by his deteriorating health and a sense of sadness and loss throughout the nation. He had been struggling with circulation problems and other health issues for several years, and his condition had worsened in the weeks leading up to his death.

The king's last public appearance was on January 31, 1952, when he attended a dinner at the Guildhall in London. He appeared frail and tired, and had to be helped up the stairs to the dais. Nevertheless, he delivered a speech that was well-received by those in attendance.

After the dinner, the king returned to his residence at Sandringham, where he had been spending the winter months. It was there that he began to feel increasingly unwell, and his condition quickly deteriorated. He was attended by his wife, Queen Elizabeth, and his physician, Lord Dawson of Penn, who administered oxygen and other treatments to try to alleviate his symptoms.

Despite these efforts, the king's condition continued to worsen, and he passed away in his sleep on the morning of February 6, 1952. He was just 56 years old.

It is not clear exactly when King George VI knew that he was going to die, as his health had been fluctuating for several years prior to his death. However, he was known to be a deeply religious man, and had expressed a sense of resignation and acceptance in the face of his declining health. He was surrounded by his family and loved ones in his final days, and was mourned deeply by the nation he had served so faithfully throughout his reign.
