King Harald V Hospitalized, Prince Haakon Regent

King Harald V of Norway was admitted to the National Hospital in Oslo on Monday, August 17, 2026, and placed on sick leave for two weeks. The 89-year-old monarch's hospitalization was announced by the Royal House, which confirmed that Crown Prince Haakon will serve as regent during his father's absence.

According to the Royal House, the King has been undergoing treatment with cortisone for hemolytic anemia, a blood disorder characterized by the premature destruction of red blood cells. This treatment recently led to fluid accumulation in his body, necessitating hospital care for further tests and treatment. The hospitalization came just ten days after a planned checkup and follow-up appointment.

The admission marks another health concern for the European Union's oldest reigning monarch, who has faced several medical issues in recent years. In February, he was hospitalized for two days in Tenerife, Spain, while on holiday with Queen Sonja, where he was treated for an infection and dehydration. In 2024, during a visit to Malaysia, his heart rate dropped to dangerously low levels, resulting in the fitting of a temporary pacemaker before he returned to Norway for a permanent implant.
