The Alarmingly Rising Prevalence of OSA
Obstructive Sleep Apnea (OSA) is becoming a significant public health issue in India. Its rising prevalence is closely linked to factors such as obesity and lifestyle changes. This document compiles key findings on the prevalence of OSA in India and compares it with global statistics.
What is Obstructive Sleep Apnea (OSA)?
Obstructive sleep apnea (OSA) is a condition where you stop breathing during sleep due to a blockage in your windpipe.
People with OSA may wake up frequently at night. This disruption can lead to daytime exhaustion and other frustrating symptoms. If left untreated, OSA increases your risk of life-threatening complications. A healthcare provider may recommend lifestyle changes or using a CPAP machine for treatment.
Key Health Hazards of OSA
How Bad Is the Situation?
Overall Prevalence
A systematic review indicates that around 11% of the Indian adult population suffers from OSA. Notably, about 5% experience moderate-to-severe OSA (AHI ≥15 events/hour)[1].
Urban vs. Rural
Urban populations have a significantly higher prevalence of severe OSA than rural areas. Studies report figures reaching up to 19.5% in urban settings[2][3].
Gender Disparities
Gender plays a role in OSA prevalence. Men are more likely to suffer from OSA compared to women. The reported prevalence rates stand at 13% for men and 5% for women[4].
Undiagnosed Cases
A crucial issue remains: many cases are undiagnosed. This is largely due to low awareness and underreporting. Only about 2% of individuals with OSA consult a physician[5].
Comparison with Global Averages
Globally, the prevalence of moderate-to-severe OSA ranges from 10% to 20% across various populations. Indian urban rates are comparable, or even higher in some studies[4].
Management and Treatment of OSA
How is Obstructive Sleep Apnea Treated?
Treatments for OSA may include:
Making lifestyle changes, such as adjusting your sleeping position (avoid sleeping on your back) and maintaining a healthy weight.
Using a continuous positive airway pressure (CPAP) machine.
Wearing oral appliances (mouthpieces).
Undergoing surgery if necessary.
CPAP Machines on Rent
BiPAP Machines Available
Common Types of Surgery
Surgery may be considered to treat OSA. Common surgical options include:
Uvulopalatopharyngoplasty (UPPP): This involves removing tissue from the back of your throat.
Tracheostomy: Opening your windpipe to bypass a blockage.
Tonsillectomy/adenoidectomy: Removing the tonsils or adenoids.
Nerve stimulation: Implanting a device to stimulate airway muscles during sleep.
