1. Screen yourself with STOP-BANG
STOP-BANG is a widely used eight-question screen for obstructive sleep apnea. Answer yes or no to each question. The more yes answers, the higher your risk, and three or more is a good reason to talk to a professional about testing.
- SSnoringDo you snore loudly, loud enough to be heard through a closed door?
- TTirednessDo you often feel tired, fatigued or sleepy during the day?
- OObservedHas anyone seen you stop breathing, choke or gasp during sleep?
- PPressureDo you have, or are you being treated for, high blood pressure?
- BBMIIs your body mass index more than 35 kg/m²?
- AAgeAre you older than 50?
- NNeckIs your neck circumference greater than 16 inches (40 cm)?
- GGenderAre you male?
2. Know the warning signs
Sleep apnea rarely announces itself. Often the person next to you notices first, and your dentist or eye doctor may spot clues before your doctor does.
At night
- Loud, regular snoring
- Pauses in breathing, choking or gasping
- Waking at 3 a.m. and struggling to get back to sleep
During the day
- Sleepiness that coffee does not fix
- Brain fog and low drive
- Nodding off at the wheel
In your health checks
- Stubborn high blood pressure
- Type 2 diabetes or a waistline that will not move
- Worn teeth, jaw clicking, floppy eyelids or dry eyes
3. Get tested
A finger oxygen clip can look reassuring while the brain spends the night in emergency mode, so a proper sleep study is how sleep apnea is confirmed. Many people can start with a home sleep test, worn in their own bed for a night. Others need a lab study. Results are usually reported as an AHI score: the number of breathing pauses and shallow breaths per hour. Chapter 10, "Diagnosis Decoded", walks through the whole process and how to read your own results.
