Obstructive Sleep Apnea (OSA) affects far more than just your sleep. Start with a quick risk assessment using STOP-Bang — the standard questionnaire used by physicians worldwide.
This is the standard screening questionnaire used in hospitals worldwide. It estimates your likelihood of having sleep apnea — it is not a medical diagnosis.
Louder than normal conversation, or loud enough to be heard through a closed door
For example: drowsy after meals, falling asleep watching TV or in meetings, or needing daily naps
For example: a partner, family member, or friend has told you, or woken up to check on you (witnessed apnea)
Including those currently on blood pressure medication or previously diagnosed by a doctor
A BMI greater than 35 kg/m² is considered a risk factor (calculated automatically)
Age over 50 is a key OSA risk factor — enter your actual age
Measure at the middle of your Adam's apple (40 cm ≈ 16 inches). If unsure, check whether your shirt collar size is larger than 16
Biological/birth gender — required for STOP-Bang risk scoring
When the airway repeatedly closes during sleep, blood oxygen drops, the heart works harder, hormones become imbalanced, and the brain wakes repeatedly — affecting your entire body across 6 critical dimensions of life.
83% of patients with treatment-resistant hypertension and 86% of obese type 2 diabetics have hidden OSA — treatment makes both conditions easier to control

The STOP-Bang questionnaire is a screening tool, not a medical diagnosis. It has high sensitivity (~88-93%) but lower specificity (~35-42%), so it should be used together with clinical history, physical examination, and other findings.
Per the 2025 guidelines from the Thai Sleep Apnea Society and the Royal College of Otolaryngologists of Thailand, a score of 3 or higher is considered high risk for OSA, and a sleep study is recommended.
