Crown Princess Mette-Marit of Norway has been placed on a waiting list for a lung transplant following a significant decline in her health due to pulmonary fibrosis, a chronic lung condition she has battled since 2018. Medical experts indicate that without the transplant, she may only have about a year to live. Professor Are Holm from Oslo University Hospital described her condition as having undergone a "dramatic deterioration." The royal palace confirmed that her health situation is life-threatening, prompting the royal family to alter their plans. Crown Prince Haakon cut short an official visit to Japan, and their daughter, Princess Ingrid Alexandra, returned from her studies in Australia. The couple has also postponed their 25th wedding anniversary celebrations. Mette-Marit will be treated like any other patient on the transplant list, which is managed by strict criteria to ensure the best chance of success. Norway typically conducts 30 to 35 lung transplants each year, and the waiting list remains relatively short, according to hospital officials.
