Apollo experts warn that a large majority of obstructive sleep apnoea cases are not identified and therefore not treated. The reports state that roughly 80% to 90% of sleep apnoea cases go undiagnosed, indicating that many people may experience symptoms without receiving a formal diagnosis. Both sources frame sleep apnoea as a significant health concern that can remain unnoticed, potentially delaying medical evaluation and care. While the articles focus on the scale of underdiagnosis, they also highlight the importance of awareness and clinical assessment for detecting the condition. The messages are consistent across outlets: underdiagnosis is widespread, and the burden of sleep apnoea likely extends beyond those already known to clinicians. The reports attribute the warning to experts associated with Apollo, using the estimated 80% to 90% range to underscore how prevalent undetected cases may be. Overall, the coverage calls attention to the diagnostic gap and the need for greater identification of sleep apnoea among affected individuals.
