Pope Francis was hospitalized before his death for issues related to which body system?

Pope Francis was hospitalized for serious issues related to his respiratory system in the weeks leading up to his passing. He spent five weeks in a Rome hospital where he was treated for a respiratory tract infection and double pneumonia. This extended stay highlighted the severity of his condition, as he experienced acute respiratory failure and required non-invasive mechanical ventilation to assist his breathing.

The pontiff's history with lung health dates back to his youth when he had part of one lung removed due to a pulmonary infection. This made him particularly vulnerable to respiratory illnesses in his later years. During his final hospitalization, the Vatican provided updates that detailed his "complex polyicrobial respiratory tract infection," indicating a multi-pronged battle against various viruses and bacteria in his lungs. Despite his frail condition and advanced age, the then 88-year-old Pope remained alert and continued to engage in some work from his hospital room, demonstrating his enduring dedication to his role.

While the immediate cause of his death was officially attributed to a cerebral stroke and irreversible cardiac arrest, his death certificate also listed "progressive episode of acute respiratory failure in multimicrobial bilateral pneumonia" as a contributing factor. This underscores the significant role his respiratory ailments played in his declining health and eventual passing. His hospital stay was a period of intense concern for Catholics worldwide, as he navigated a series of health setbacks, including breathing crises and mild kidney insufficiency, before his return to the Vatican.
