The sound made when air passes through a narrowed upper airway, causing surrounding tissues to vibrate. Many people who snore don't have OSA — but loud, habitual snoring is one of the cardinal signs of OSA.
A condition in which the upper-airway muscles relax during sleep, causing the airway to collapse. Airflow becomes reduced (hypopnea) or stops entirely (apnea), producing drops in blood oxygen and forcing the brain to wake briefly so breathing can resume.
In Thailand, OSA prevalence is approximately 15.4% in men and 6.3% in women based on general-population studies.
If you or someone close to you notices any of these, it's worth speaking with the doctor to assess your OSA risk.
Snoring louder than normal conversation, audible through a closed door, or disturbing your sleep partner.
A partner, family member, or roommate observes you stop breathing or gasp during sleep.
Waking suddenly short of breath, choking on air, or with night sweats.
Falling asleep watching TV, in meetings, or while driving — despite a full night's sleep.
Waking unrefreshed with morning fatigue, headaches, or poor concentration.
Tossing, turning, fragmented sleep, or the sense that you never sleep deeply.
Risk can be assessed from medical history, physical exam, or the STOP-Bang questionnaire.
If you have any of the following, OSA evaluation is worth pursuing even with a low STOP-Bang score:
For public safety, OSA screening is recommended for: pilots · commercial / fuel-truck drivers · operators of complex or high-risk machinery — even when no symptoms are reported.
Long-term untreated OSA materially affects your health and longevity.
Coronary artery disease and arrhythmias such as atrial fibrillation.
Especially drug-resistant hypertension, plus pulmonary hypertension.
Elevated risk of cerebrovascular events, with long-term impact on function.
Daytime sleepiness raises the risk of motor-vehicle and workplace accidents.
Affects focus, mood, relationships, and work performance.
Worsens diabetes, depression, kidney disease, and obesity.
OSA is diagnosed via a sleep study, which measures the AHI (Apnea-Hypopnea Index) — the number of breathing pauses or shallow-breathing events per hour. Severity is graded as:
Several test types exist, varying by equipment complexity: Type 4 (pulse-oximeter screening), Type 3 (multi-channel home test for OSA diagnosis with physician), Type 2 (full home PSG with EEG / EOG / EMG / ECG channels), and Type 1 (full in-lab PSG).

The doctor selects the right approach based on disease severity, patient preferences, and individual anatomy — a comprehensive multidimensional evaluation.
Sleep hygiene education and weight loss. Structured follow-up substantially outperforms generic advice.
Suitable for: All patients — the foundation of any treatment plan.
Includes CPAP (continuous), APAP (auto-adjusting), BiPAP (bi-level), and ASV — acting as a "pneumatic splint" to keep the airway open. High efficacy, low risk.
Suitable for: AHI ≥ 15, marked daytime sleepiness, elevated BMI, or significant comorbidities — the recommended first-line therapy. Soma Wellness Prime includes a free 1-week CPAP trial with every Type 3 or Type 2 sleep study.
The most common is a Mandibular Advancement Device (MAD), which advances the lower jaw to open the airway. Custom-fitted by a dentist with periodic adjustments.
Suitable for: Mild-to-moderate OSA, or patients who can't tolerate PAP (e.g., frequent travellers).
Radiofrequency (RF) on the nose, soft palate, or tongue base, and Erbium YAG laser for snoring and mild OSA.
Suitable for: Snoring with low OSA risk, or mild OSA. CO₂ laser LAUP is not recommended due to low success rates and high complication rates.
Several types, depending on the level of obstruction:
Suitable for: Patients declining PAP, younger patients, BMI < 40, or with a clear anatomic obstruction.
Combining multiple approaches for better outcomes. Useful when single-modality treatment doesn't meet expectations.
