Take the Behavioral QuizThe Silent Epidemic: Sleep Apnea in America
Obstructive sleep apnea (OSA) affects an estimated 30 million Americans, yet the American Academy of Sleep Medicine estimates that 80% of cases remain undiagnosed. This treatment gap has profound health consequences: untreated sleep apnea is a significant risk factor for hypertension, type 2 diabetes, heart disease, stroke, and motor vehicle accidents.
If your sleep score is consistently low despite spending adequate time in bed — particularly if you snore, wake with headaches, or are excessively sleepy during the day — sleep apnea screening should be your priority.
The 12 Warning Signs of Sleep Apnea
- Loud, chronic snoring — The most common symptom, though not all snorers have OSA
- Observed breathing pauses — A sleeping partner notices you stop breathing
- Gasping or choking during sleep — Sudden awakening with shortness of breath
- Excessive daytime sleepiness (EDS) — Falling asleep during routine activities
- Morning headaches — Caused by reduced oxygen and elevated CO2 during sleep
- Dry mouth or sore throat upon waking — Common in mouth-breathing OSA
- Difficulty concentrating or memory problems
- Mood changes, irritability, or depression
- Frequent nighttime urination (nocturia)
- High blood pressure — Present in 50% of OSA patients
- Decreased libido or sexual dysfunction
- Waking with chest tightness

Frequently Asked Questions
What are the main warning signs of sleep apnea?
The main warning signs are: loud chronic snoring, observed breathing pauses during sleep, gasping or choking sounds, excessive daytime sleepiness despite adequate sleep time, morning headaches, dry mouth upon waking, and difficulty concentrating. A sleeping partner is often the first to notice the snoring and pauses.
Can you have sleep apnea without knowing it?
Yes — the AASM estimates 80% of moderate-to-severe sleep apnea cases remain undiagnosed. Most people have no memory of the micro-arousals caused by apnea events. The primary clues are daytime symptoms (excessive sleepiness, headaches) and partner reports of snoring and breathing pauses.
How is sleep apnea tested?
Sleep apnea is diagnosed via sleep study. At-home sleep apnea tests (HSATs) are the first-line recommendation for most suspected cases — they measure oxygen saturation, breathing effort, and airflow. In-lab polysomnography (PSG) is for complex cases. The key diagnostic metric is the Apnea-Hypopnea Index (AHI).
