Sleep apnea is one of the most common — and most underdiagnosed — sleep disorders in the United States. It's estimated that roughly 30 million Americans have obstructive sleep apnea (OSA), yet up to 80% of moderate-to-severe cases remain undiagnosed. At Pulmonary & Sleep Experts PLLC, we see the consequences of this diagnostic gap every day.
What Is Obstructive Sleep Apnea?
Obstructive sleep apnea occurs when the muscles in the back of your throat relax excessively during sleep, causing the airway to narrow or close completely. When this happens, your brain briefly wakes you up to reopen the airway — sometimes hundreds of times per night. Most people don't remember these awakenings, but the cumulative effect on sleep quality is significant.
Warning Signs You Shouldn't Ignore
The most recognized symptom is loud, chronic snoring — but sleep apnea goes far beyond snoring. Watch for these warning signs:
Witnessed breathing pauses: If a partner or family member has noticed you stop breathing during sleep, this is one of the strongest indicators of OSA.
Excessive daytime sleepiness: Feeling exhausted despite what seems like a full night of sleep is a hallmark symptom. This isn't ordinary tiredness — it's the kind of fatigue that makes it difficult to stay awake during meetings, while driving, or during routine activities.
Morning headaches: Repeated drops in blood oxygen overnight can trigger headaches that are typically present upon waking and improve within a few hours.
Difficulty concentrating and memory problems: Fragmented sleep disrupts the brain's ability to consolidate memories and maintain focus during the day.
Mood changes: Irritability, anxiety, and depression are all associated with untreated sleep apnea. Many patients report significant improvements in mood once they begin treatment.
Frequent nighttime urination: Getting up to use the bathroom two or more times per night (nocturia) is a surprisingly common sign of OSA that many patients don't connect to a sleep disorder.
Why Early Diagnosis Matters
Untreated sleep apnea isn't just about feeling tired. The repeated drops in blood oxygen and the stress response triggered by each awakening take a serious toll on your cardiovascular system. Research has shown that untreated OSA significantly increases your risk of:
- check_circleHypertension — Sleep apnea is one of the most common identifiable causes of resistant high blood pressure.
- check_circleHeart disease and heart failure — The strain on the heart from nightly oxygen desaturation is cumulative.
- check_circleStroke — OSA is an independent risk factor for stroke, particularly in men.
- check_circleType 2 diabetes — Sleep apnea disrupts glucose metabolism and insulin sensitivity.
- check_circleAtrial fibrillation — Patients with untreated OSA have a significantly higher risk of developing irregular heart rhythms.
How We Diagnose Sleep Apnea
At our Garden City, Novi, and Taylor locations, we offer both in-lab polysomnography (the gold standard) and convenient home sleep testing. The right option depends on your symptoms, medical history, and preferences. During your initial consultation, we'll review your symptoms, perform a focused physical examination, and determine the most appropriate diagnostic path.
For patients who prefer the convenience of testing at home, our portable monitors track breathing patterns, oxygen saturation, and heart rate overnight. Results are interpreted by our board-certified sleep specialists, typically within 48 hours.
Treatment Options
The most effective treatment for moderate-to-severe OSA is continuous positive airway pressure (CPAP) therapy. Modern CPAP machines are quieter, smaller, and more comfortable than ever before. We work closely with each patient on mask fitting, pressure optimization, and ongoing compliance support.
For patients who cannot tolerate CPAP, we coordinate referrals for oral appliance therapy, positional therapy, and surgical evaluation when appropriate. The goal is always to find a sustainable treatment that you'll actually use consistently.
Take the First Step
If you or a loved one are experiencing any of these symptoms, don't wait. Early diagnosis and treatment can dramatically improve your quality of life and protect your long-term health. You can start with our online Sleep Apnea Quiz for a quick self-assessment, or request an appointment directly — most patients are seen within days.
