Sleep apnea screening
Untreated obstructive sleep apnea drives cardiovascular and metabolic risk. Screen if you snore loudly, are tired despite enough hours, or have hypertension.
Why
Obstructive sleep apnea (OSA) is common (~10-15% of adults), often undiagnosed, and causally linked to hypertension, cardiovascular events, cognitive decline, and all-cause mortality. STOP-BANG is the most validated screening questionnaire. Diagnosis is by polysomnography or home sleep apnea testing. CPAP and other treatments substantially reduce risk in moderate-severe OSA.
The program
- 1
Take the STOP-BANG questionnaire (free online).
- 2
If 3+ positives, ask your GP for a sleep study referral.
- 3
Home sleep apnea testing or in-lab polysomnography confirms the diagnosis.
- 4
If moderate-severe, options include CPAP, mandibular advancement device, weight loss, positional therapy.
- 5
Re-screen if sleep quality degrades again after weight or lifestyle change.
Practical
Cadence
One-time screening; re-test if symptoms return

STOP-BANG questionnaire (online, 8 yes/no questions)
Ideal for

Evidence
AASM 2017 clinical practice guideline (Kapur et al., J Clin Sleep Med) recommends polysomnography or home sleep apnea testing for symptomatic adults; Wisconsin Sleep Cohort (Peppard 2013) estimates moderate-to-severe OSA prevalence at 10–17% of middle-aged adults and finds most cases undiagnosed.
