In a statement released on Tuesday, the palace said the 89-year-old monarch is receiving treatment at Oslo University Hospital and has suspended his royal duties for an unspecified period.
King Harald V, who has reigned over Norway for more than 30 years, was admitted to hospital last week and was subsequently placed on medical leave.
During his absence, his son, 53-year-old Crown Prince Haakon, has taken over the King’s duties on a temporary basis.
The King had already been receiving treatment for haemolytic anaemia, a rare blood disorder that causes a reduction in red blood cells and can lead to fatigue and breathing difficulties.
In 2024, the Royal Palace announced that Harald V would reduce his public engagements because of his age. Later that year, he was fitted with a pacemaker after experiencing health problems while on holiday in Malaysia.
The Norwegian royal family has faced a series of challenges in 2026.
Crown Princess Mette-Marit, the wife of Crown Prince Haakon, underwent a lung transplant in June 2026 after living with pulmonary fibrosis since 2018.
The family has also faced controversy involving Mette-Marit’s son, Marius Borg Høiby, who was sentenced to four years in prison after being convicted on two counts of rape. He had denied the most serious allegations against him, and his lawyers said they planned to appeal.
Earlier this year, documents also emerged showing that Mette-Marit had maintained contact with convicted sex offender Jeffrey Epstein. She later apologized to Norway’s King and Queen, saying she had exercised poor judgment.
