King Harald of Norway, Europe's oldest monarch, has been admitted to hospital and placed on sick leave due to a rare blood condition called haemolytic anaemia. This condition causes a reduction in red blood cells, leading to fatigue and shortness of breath. The Norwegian Palace announced that the 89-year-old king has been treated with cortisone for the blood disease in recent weeks, resulting in fluid accumulation that requires hospital treatment. This news comes just days after the king was taken to hospital for a routine check-up, with the palace initially denying any serious issues. King Harald's health has been a concern for some time, with a history of infections, dehydration, and a pacemaker fitted in 2024. In January 2024, he was put on sick leave due to a respiratory infection, and he has also been hospitalised for infections in May and December 2023. The king's recent health struggles are particularly notable given the recent health issues faced by his family, including his daughter-in-law, Crown Princess Mette-Marit, who underwent a lung transplant in June due to worsening pulmonary fibrosis. King Harald's ongoing health concerns raise questions about the future of the Norwegian monarchy and the potential need for a smooth transition of power to his son, Crown Prince Haakon. As the palace does not provide further details on his recovery, the nation awaits updates on the king's health and the impact on his public duties.
