Crown Princess Mette-Marit of Norway may require a lung transplant due to worsening health from pulmonary fibrosis, diagnosed in 2018. Her condition has deteriorated, prompting her healthcare team to prepare for potential surgery. Despite her illness, she wishes to continue her royal duties. Her husband, Prince Haakon, noted her increasing struggles with breathing and energy levels. The situation is compounded by recent legal issues involving her son, Marius Borg Høiby.
