As more people live, work, and travel at high altitudes, experts are calling for major shifts in the way altitude-related health conditions are understood, diagnosed, and treated. A new perspective has been revealed Signal transduction and targeted therapy We highlight the increasing disease burden associated with hypoxic environments and introduce a comprehensive framework designed to advance the future of high-altitude medicine.
High-altitude regions, generally defined as areas above 2,500 meters above sea level, are home to millions of permanent residents and are visited by many tourists each year. Exposure to reduced oxygen levels can affect multiple organs and cause a wide range of symptoms, including acute mountain sickness, pulmonary complications, cardiovascular and metabolic disorders, and long-term organ damage. Despite advances in our understanding of altitude sickness over the decades, many symptoms continue to be seen and managed individually.
This paper proposes a new model known as hypoxic stress-induced multisystem injury (HSMI). This views high altitude-related diseases as interconnected symptoms of a common underlying process. Rather than focusing on isolated organs, this framework emphasizes how oxygen deprivation triggers a wide range of biological responses that can have long-term effects on the lungs, brain, heart, liver, kidneys, and gastrointestinal system.
”For decades, high altitude-related diseases were treated as a separate issue. ” Professor Fengmin Luo, lead author of the study from West China Hospital of Sichuan University, said: ”HSMI shows that these are interrelated responses to oxygen deprivation. It changes the way we think about early diagnosis and prevention“This integrated perspective could help overcome long-standing challenges in this field. Current diagnostic approaches often rely heavily on symptoms rather than objective biological indicators, making early detection difficult. This article highlights the need for real-time diagnostics, advanced biomarkers, portable imaging techniques, and continuous physiological monitoring that can identify health risks before severe symptoms develop.”
The proposed roadmap also focuses on understanding why individuals respond differently to exposure to high altitudes. Factors such as genetics, age, sex, and population-specific adaptations can influence vulnerability to hypoxia. Incorporating multi-omics technologies, artificial intelligence, and predictive modeling may enable more individualized risk assessments and prevention strategies for people who climb or live at high altitudes.
Additionally, this article outlines opportunities to develop precision therapeutics targeting the biological mechanisms that cause altitude-related diseases. Such an approach could go beyond symptom management and support interventions aimed at preventing or reducing long-term organ damage associated with chronic hypoxia.
As global engagement with high-altitude environments continues to expand, the HSMI framework offers a new vision for prevention, diagnosis, and treatment, providing the basis for more tailored and effective healthcare strategies in some of the world’s most challenging environments.
