Nearly 1 Billion People Have Sleep Apnea. Here's the UAE's Share of That.

Sleep apnea has quietly become one of the most common chronic conditions on the planet — and one of the least talked about. It doesn't announce itself the way a broken bone or a fever does; it shows up as exhaustion that coffee can't fix, a partner nudging you awake because you'd stopped breathing, or a blood pressure reading your doctor can't quite explain. Below is the actual scale of the problem, drawn from global epidemiological research, alongside the numbers specific to the UAE and the wider Gulf — a region where the condition's biggest risk factor happens to be unusually common.

How Many People Actually Have Sleep Apnea?

The most widely cited estimate comes from a landmark analysis published in The Lancet Respiratory Medicine, which pooled data from studies across 16 countries and arrived at a striking figure: roughly 936 million adults aged 30 to 69 worldwide live with some degree of obstructive sleep apnea (OSA), the type caused by the airway physically collapsing during sleep. Of those, an estimated 425 million have moderate-to-severe disease — the range where health complications become significantly more likely. A separate, much rarer form, central sleep apnea (CSA), where the brain itself fails to signal the breathing muscles correctly, affects roughly 0.9% of adults, or somewhere near 80 million people globally.

What makes those figures more concerning is the trajectory. Follow-up research tracking the same data over the following decade found global OSA prevalence had climbed by roughly 12%, with the steepest increases in rapidly urbanizing regions of Asia and Latin America — a pattern researchers link directly to rising obesity rates and changing lifestyles rather than better diagnostic tools alone. The undiagnosed share of that figure is arguably the more important number for anyone reading this: the overwhelming majority of people carrying this condition have no idea they have it, because sleep apnea rarely produces symptoms severe enough to prompt a doctor's visit on its own — it's usually a partner, a routine blood pressure check, or years of unexplained fatigue that eventually connects the dots.

Sleep Apnea in the UAE and the Wider Gulf

This is where the global numbers stop being abstract for anyone living in the region. The UAE and its GCC neighbors carry some of the highest obesity rates on earth — and obesity is, by a wide margin, the single strongest predictor of obstructive sleep apnea. That combination shows up clearly in the region's own clinical research.

Who Is Most at Risk? — Global Demographics

Sleep apnea doesn't distribute evenly across age, sex, or body type, and understanding the pattern helps explain why certain people are diagnosed late or missed entirely.

Sex Differences

Research consistently shows a higher prevalence in men — an estimated 38% of men aged 30 to 70 have some degree of OSA, compared with around 23% of women in the same age range. Men are also more likely to present with the "textbook" symptoms clinicians screen for: loud snoring, witnessed pauses in breathing, and gasping on waking. Women, by contrast, more often report vaguer symptoms — fatigue, low mood, or insomnia — which are more easily mistaken for something else entirely. That difference in presentation is thought to be a meaningful contributor to underdiagnosis in women specifically. Hormonal shifts also matter here: menopause raises a woman's risk to a level approaching that of men, and pregnancy carries its own spike — some studies suggest up to a quarter of women may develop OSA symptoms by the third trimester, likely linked to weight gain and hormonal changes affecting airway tone.

Age

Risk climbs steadily with age. Adults over 65 are roughly twice as likely to have the condition as middle-aged adults, with an estimated half of that age group showing at least mild OSA and around one in five experiencing moderate-to-severe disease. Children are far less commonly affected but not immune — pediatric OSA is estimated at 1–6% globally, with central sleep apnea affecting a further 1–5% of children, usually linked to enlarged tonsils, obesity, or underlying neurological conditions.

Weight

Obesity remains the single strongest modifiable risk factor identified in the research. An estimated 40% of people with obesity have OSA, and the relationship compounds further with pregnancy, where 15–20% of obese expectant mothers go on to develop the condition. Notably, researchers have found that as people age, body weight becomes a somewhat less dominant factor relative to other physiological changes — meaning older adults can develop significant OSA even without carrying excess weight.

Symptoms and the Toll on Daily Life

Sleep apnea's symptoms range from mildly annoying to genuinely disabling, and severity tends to track closely with how disrupted a person's sleep architecture actually is.

The cognitive impact deserves particular attention because it's so often dismissed as ordinary tiredness. Studies consistently link untreated OSA to poorer short-term memory, reduced attention span, and weaker executive function — the mental processes involved in planning, decision-making, and impulse control. Encouragingly, this appears to be at least partially reversible: reviews of treatment outcomes found the majority of relevant studies recorded measurable improvements in verbal fluency and working memory once effective therapy was underway.

The Long-Term Health Risks

Beyond disrupted sleep, untreated OSA is associated with a genuinely wide range of serious health complications — a large part of why sleep specialists push so hard for diagnosis and treatment rather than treating loud snoring as background noise.

Cardiovascular Disease and Mortality

Research from the American Academy of Sleep Medicine found that people with untreated sleep apnea face roughly triple the mortality risk of those without the condition, with cardiovascular disease and stroke accounting for an estimated 42% of those deaths. The cardiovascular connections run deep: OSA roughly doubles the risk of heart attack, raises the likelihood of developing cardiovascular disease by around 71%, and is linked to a 48% higher risk of coronary heart disease. Among people already living with atrial fibrillation or heart failure, sleep apnea is disproportionately common — some studies place the overlap with A-Fib as high as 74%.

Blood Pressure and Stroke

Up to half of all OSA cases are accompanied by high blood pressure, and the relationship appears to scale with severity — people with moderate OSA show notably higher odds of a hypertension diagnosis than those without the condition. Among younger adults with otherwise unexplained high blood pressure, researchers estimate a striking 89% may actually have undiagnosed OSA underneath it. Stroke risk follows a similar pattern, rising with both age and disease severity, with some research linking untreated OSA to as much as an 86% higher likelihood of stroke.

Diabetes and Metabolic Health

The relationship between OSA and blood sugar regulation runs in both directions. Studies estimate that up to two-thirds of people with OSA show signs of prediabetes, and some research places the crossover with confirmed Type 2 Diabetes as high as 83%. Researchers studying the mechanism found untreated sleep apnea can trigger measurable blood sugar spikes within hours of falling asleep — a finding with obvious relevance for the Gulf region, where diabetes prevalence is already among the highest in the world.

Mental Health

Nearly half of people with sleep apnea in pooled studies also meet criteria for a diagnosable mental health condition, most commonly anxiety (affecting an estimated 54% of OSA patients in one large study) and depression (46% in the same research). Whether disrupted sleep drives the mental health symptoms, the underlying physiology works both ways, or some combination of the two, is still debated — but the overlap itself is well established.

Treatment: What Actually Works

CPAP therapy remains the gold-standard treatment worldwide, and the outcome data supports why. Clinical reviews consistently report an 80% success rate among patients who stay compliant with therapy, and one large longitudinal study found regular CPAP use was associated with a 61% reduction in premature death risk and a 77% reduction in heart failure risk over the study period. The same body of research links consistent CPAP use to roughly a 70% reduction in road traffic accident risk among affected drivers — a meaningful public safety point, given that untreated OSA is separately associated with more than double the risk of being involved in a motor vehicle collision. Choosing between a standard Auto CPAP and a BiPAP machine usually comes down to pressure needs your sleep specialist can confirm from your diagnostic study — our CPAP, APAP & BiPAP Explained and How to Choose the Right CPAP Machine guides break down exactly how that decision gets made.

CPAP isn't the only option, and it's worth knowing the alternatives exist for the roughly one-third to one-half of new CPAP users who abandon therapy within the first year — usually over mask comfort or claustrophobia rather than the therapy itself; our guide to CPAP masks, claustrophobia and anxiety addresses that specific barrier directly. If that's the barrier, our Full Face Mask, Nasal Mask, and Nasal Pillow Mask comparison guides — alongside our article on choosing the right CPAP mask — walk through which design actually suits different sleep styles and face shapes. Oral appliance therapy — custom-fitted devices that reposition the jaw during sleep — shows compliance rates as high as 90% in some studies, meaningfully higher than CPAP, with mandibular advancement devices reducing breathing events in an estimated 86% of users. Positional therapy, which addresses the roughly 56% of OSA cases linked specifically to sleeping position, has been shown to improve breathing events by around 54% simply by keeping patients off their back. Surgical options and implantable nerve stimulators exist for select cases, alongside straightforward lifestyle interventions — one clinical trial found that diet and exercise alone cut the average number of breathing disruptions per hour nearly in half. It's also worth knowing that CPAP therapy itself can come with manageable side effects — dry mouth, congestion, or mask marks — which our guide on CPAP therapy side effects and how to prevent them covers in detail.
