Obstructive Sleep Apnea (OSA) is a chronic sleep related breathing disorder with complete or partial blockage of the upper airway during sleep. These interruptions during sleep, impact oxygen flow to the lungs (and subsequent delivery to vital organs), degrades sleep quality and overall health. Symptoms of OSA include loud snoring, insomnia, fatigue, dry mouth/sore throat, short-term memory losses, difficulty in concentration, morning headaches, and even depression.
While obesity or sedentary habits can increase risk, many people with OSA are neither overweight nor unhealthy and are affected by OSA due to anatomical (narrow upper airways) and physiological factors.
Globally, OSA affects around 1 billion people worldwide, which equals to approximately 20% of the total adult population. India ranks 4th worldwide with approximately 52 million Indians having OSA, as per a 2019 global prevalence study1. A 2024 AIIMS meta-analysis highlight that around 104 million Indians are affected with OSA of whom 47 million patients have moderate to severe OSA2. However, a majority of them remain clinically undiagnosed (80%)3 and untreated, primarily due to lack of awareness of the disorder, stigma and access to care.
OSA also significantly impacts women, especially during pregnancy and menopause, often presenting with atypical symptoms. In a study it was found prevalence increases with age—24% in women aged 20–44, 56% in those 45–54, and 75% in the 55–70 age group4. In children, OSA often due to enlarged tonsils or adenoids can lead to behavioural problems or poor academic performance and is often mistaken for ADHD5.
There is substantial evidence that suggest OSA has high association with co-morbid conditions like type 2 diabetes mellitus3 (52%), drug resistant hypertension3 (83%), heart failure6 (76%), stroke7 (63%), coronary artery disease8 (57%), atrial fibrillation9 (49%), depression10 (45%) and morbid obesity11 (70%). A recent Lancet study reinforces that untreated OSA is a major but modifiable risk factor for both all-cause and cardiovascular-related death, highlighting the importance of consistent CPAP use12.
Recognising this, the Research Society for Study of Diabetes, India (RSSDI) and American Heart Association (AHA), recommends screening, diagnosis, and treatment of OSA in patients with T2DM at initial stages13, resistant/poorly controlled hypertension, pulmonary hypertension, and recurrent atrial fibrillation14 and in patients with an ischemic stroke15 respectively.
To guide Indian clinical practice, the Indian Initiative on Obstructive Sleep Apnea (INOSA) guidelines was published in 2014 under the auspices of Ministry of health and family welfare, Government of India. This initiative provides comprehensive guidelines for the diagnosis, risk assessment, and management of OSA in India’s healthcare system16.
Beyond clinical impacts, untreated Obstructive Sleep Apnea (OSA) imposes a considerable economic burden. In the United States, it contributes to an estimated $86.9 billion in lost productivity, $15.9 billion due to road traffic accidents, and 1,400 preventable deaths annually. Individuals with untreated OSA also incur nearly twice the healthcare costs compared to those without the condition17. European data echoes this burden, where annual per-patient costs range from €236 to €28,267 depending on disease severity, with Italy alone experiencing national losses between €10.7 and €32 billion18. These figures show that delayed OSA diagnosis and treatment harm health and place a costly burden on health systems and economies.
Insurance Coverage for Sleep Apnea: India vs Global Models
Despite the rising burden of Obstructive Sleep Apnea (OSA), coverage under Indian health insurance remains limited. Patients often pay out-of-pocket for diagnosis and treatment. while insurers end up covering costly complications like stroke, heart disease, and hypertension—without addressing OSA as the root cause. The absence of standardized protocols and low awareness among payers and providers are key barriers to designing suitable insurance products.
Some insurers are taking early steps. by extending coverage that includes coverage for sleep apnea and insomnia, along with sleep studies . Some plans further includes CPAP/Bilevels device support post-hospitalization, with defined waiting periods for broader access. There are also policies that also covers costs related to buying or renting CPAP equipment under its Durable Medical Equipment benefit.
Several countries have established robust frameworks that recognize the long-term health and economic burden of OSA.
Key Recommendations for India
To integrate sleep apnea into mainstream health insurance, the following steps are critical:
