Sleep Apnea & Diagnosis

Everything about sleep apnea: symptoms, screening, testing, diagnosis, and what your results mean.

Sleep apnea is one of the most under-diagnosed chronic conditions in adults. Articles in this category cover the screening process, the diagnostic study, what your results actually mean, and the conditions that frequently coexist with obstructive sleep apnea (OSA). The framing is informational, not diagnostic; only a sleep physician can diagnose sleep apnea, and the right first step for most readers is a screening conversation with their primary care provider.

Useful entry points by where you are: if you suspect you might have OSA, the STOP-BANG screener is the validated 8-question pre-test. If you just got diagnosed, your first 30 days on CPAP is the realistic onboarding read. Veterans pursuing or protecting a service- connected disability rating should start at CPAP for Veterans.

Sleep apnea rarely travels alone. Many of the articles here also touch on the common comorbidities (cardiovascular disease, hypertension, insulin resistance, mood disorders) so that pursuing a workup leads to a complete picture rather than a single number on a sleep-study report.
