A 42-year-old member from Australia became ill while trekking along the K2 route near Urdukas Base Camp. Over four days, he experienced worsening abdominal cramping, frequent diarrhea and intermittent pain. A general practitioner on the expedition examined him and noted possible signs of infection. Though initially manageable, his symptoms persisted, prompting a recommendation to join his partner’s planned evacuation. Global Rescue coordinated helicopter transport from Paiyu Army Camp after bad weather prevented access to Urdukas. Once evacuated, he was transported by ground to a hospital in Skardu where he was diagnosed with gastroenteritis. After receiving medical care including fluids and rest, his condition improved, and he was discharged in stable condition. He remained under observation for a short period before resuming travel. This case underscores the risks of gastrointestinal illness in remote, high-altitude environments and the benefits of shared evacuation coordination for expedition teams.
