The Dangerous Condition You Might Not Know You Have
You snore loudly. Your partner has noticed you stop breathing during sleep. You wake up with a headache and a dry mouth. Despite seemingly adequate sleep, you are exhausted during the day, struggling to concentrate, and falling asleep at your desk. These are the hallmarks of obstructive sleep apnoea (OSA) – a condition that affects an estimated 5-15% of adults and is seriously underdiagnosed.
At our practice in Zürich Seefeld, I screen for sleep apnoea proactively because it is a major, modifiable risk factor for cardiovascular disease, diabetes, and cognitive decline – and because treatment can be life-changing.
What Is Sleep Apnoea?
In obstructive sleep apnoea, the upper airway repeatedly collapses during sleep, causing breathing to stop for 10 seconds or more. These apnoeas can occur dozens or even hundreds of times per night. Each episode triggers a micro-arousal (brief awakening), a surge in blood pressure and heart rate, and a drop in blood oxygen. You may not consciously wake up, but your sleep architecture is shattered.
Symptoms and Signs
Loud, irregular snoring (often reported by bed partners), witnessed apnoeas (breathing pauses during sleep), excessive daytime sleepiness, morning headaches, dry mouth upon waking, difficulty concentrating and memory problems, irritability and mood changes, nocturia (frequent nighttime urination), decreased libido, and unrefreshing sleep despite adequate hours.
Why Sleep Apnoea Is Dangerous
Untreated OSA significantly increases the risk of hypertension (it is the leading cause of resistant hypertension), atrial fibrillation and other arrhythmias, heart attack and stroke, type 2 diabetes, cognitive decline and dementia, depression, and motor vehicle accidents from daytime drowsiness. The repeated oxygen drops and sympathetic nervous system surges cause cumulative cardiovascular damage.
Who Is at Risk?
While obesity is the strongest risk factor, sleep apnoea affects lean individuals too. Other risk factors include male sex (though women are increasingly recognised, especially post-menopause), age over 40, large neck circumference, anatomical factors (large tongue, recessed jaw, large tonsils), alcohol consumption (relaxes upper airway muscles), sedative use, and family history.
Our Diagnostic Approach
I use validated screening questionnaires (Epworth Sleepiness Scale, STOP-BANG) and clinical assessment to identify patients who need testing. Diagnosis is confirmed through a sleep study – either in-laboratory polysomnography or a home sleep apnoea test, depending on clinical suspicion and patient preference. I also assess for associated conditions: hypertension, metabolic syndrome, thyroid function, and cardiovascular risk.
What We Do: Comprehensive Sleep Apnoea Management
CPAP therapy: Continuous Positive Airway Pressure remains the gold standard treatment for moderate to severe OSA. Modern devices are quieter, more comfortable, and more effective than older models. I support patients through the adjustment period.
Oral appliance therapy: For mild to moderate OSA or CPAP-intolerant patients, mandibular advancement devices can be effective. I coordinate with dental sleep medicine specialists.
Weight management: Weight loss of 10-15% can significantly reduce OSA severity. For some patients, it can be curative.
Positional therapy: For patients with position-dependent OSA (worse when sleeping on the back), positional devices can be helpful.
Lifestyle modifications: Alcohol avoidance in the evening, optimal sleep positioning, and nasal breathing optimisation.
Cardiovascular risk management: Treating the associated conditions that OSA creates or worsens.
Conclusion
Sleep apnoea is common, dangerous, and treatable. If you snore loudly, feel excessively tired during the day, or have been told you stop breathing in your sleep, do not ignore it. Book an evaluation at our practice in Zürich Seefeld – diagnosing and treating sleep apnoea may be the single most impactful thing you do for your long-term health.
