Ant Middleton says he was distressed after his son Gabriel had difficulty breathing during their recent Mount Everest trek. In statements reported by outlets, Middleton describes seeing his son “struggling to breathe” as particularly painful, saying it “broke his heart.” He links the moment to time spent at high altitude, including the “death zone” near the summit, during which extreme conditions can make breathing difficult. Middleton also says he became the youngest British person to reach the summit on the same climb. The reports focus on his account of his son’s health during the ascent and the emotional impact on him as a parent, rather than on medical details or an explicit description of what caused the breathing difficulty. Overall, the sources agree that Middleton reached Everest and that he subsequently spoke about how hard it was to watch his son struggle to breathe during the expedition.
