The Norwegian Royal Household has confirmed that Crown Princess Mette-Marit, 52, has completed a successful lung transplant at a hospital in Oslo, bringing a wave of cautious relief across the kingdom after months of declining health.
Mette-Marit first received a diagnosis of a rare, progressive form of pulmonary fibrosis in 2018, a condition that gradually scarred her lung tissue and caused persistent breathing difficulties. As her symptoms worsened over the past year, she began stepping back from official royal engagements, with her medical team describing her condition as significantly deteriorated and “dangerous” earlier in 2025. Just 12 days before the transplant procedure, the palace confirmed she had been added to the national organ transplant waiting list— a step doctors only take when a patient is estimated to have less than 12 months left to live, with priority given to the most critically ill cases.
Her last public appearance came on May 17, when she was photographed using a nasal breathing tube connected to a portable oxygen device to manage her symptoms. Following the operation, lead lung specialist Are Holm shared positive updates in an official statement released by the royal palace. “We are delighted that everything has progressed well so far,” Holm said, noting that the Crown Princess will remain under close medical observation in the hospital for the next several weeks, a standard protocol for all recent organ transplant recipients. Holm also cautioned that the road to recovery remains fragile: transplant recipients must take lifelong immunosuppressive medications to prevent organ rejection, and data shows one in eight donor lung recipients do not survive the first year post-procedure, while roughly half are still alive after a decade.
Crown Prince Haakon, Mette-Marit’s husband of 24 years, has announced he will adjust all upcoming official commitments to be by his wife’s side during her initial recovery. The transplant comes amid an exceptionally difficult period for the Norwegian royal family, marked by two major controversies in recent months. Just two days before the procedure, Mette-Marit’s 29-year-old son Marius Borg Høiby was sentenced to four years in prison following conviction on two counts of rape. Though Høiby—who was four when his mother married Haakon and holds no official royal title—pled guilty to lesser included offenses, he maintains his innocence on the most serious charges, and his legal team has already confirmed plans to appeal the verdict. Prior to the sentencing, Høiby’s lawyers repeatedly requested his temporary release from custody to allow him to visit his ailing mother, but all such requests were denied.
Earlier this year, the royal family faced another public scandal when documents were released revealing Mette-Marit’s three-year friendship with the deceased disgraced financier and convicted sex offender Jeffrey Epstein. Mette-Marit later issued a public apology to King Harald V and Queen Sonja of Norway, acknowledged she had exercised “poor judgement” in maintaining the relationship, and stated in a national television interview that she regretted ever meeting Epstein.
Norwegian royal commentator and historian Ole-Jørgen Schulsrud-Hansen called the successful transplant positive news for both the royal family and the entire nation. “This was one of the most serious obstacles on the road for a better health for the Crown Princess, and I think many people are relieved the transplant was successful,” Schulsrud-Hansen noted.
