Sleep Apnea
Sleep apnea—most commonly obstructive sleep apnea (OSA)—is a disorder of recurrent upper‑airway collapse during sleep that leads to intermittent hypoxemia, fragmented sleep, and day‑to‑day symptoms (sleepiness, non‑restorative sleep, morning headache) along with long‑term cardiometabolic risks. Western medicine defines and stages OSA using polysomnography or home sleep apnea testing, quantifying the apnea‑hypopnea index (AHI): mild (5–14), moderate (15–29), and severe (≥30 events/hour), with diagnosis at AHI ≥15 or ≥5 with typical symptoms/comorbidities. Continuous positive airway pressure (CPAP) remains the gold standard therapy across severities because it pneumatically splints the airway, reliably normalizing respiratory events when used. Alternatives and adjuncts include mandibular advancement oral appliances, positional therapy, targeted surgeries (from uvulopalatopharyngoplasty to maxillomandibular advancement and hypoglossal nerve stimulation), weight reduction, and management of nasal obstruction. Evidence for cardiovascular event reduction with CPAP is nuanced: while it improves sleepiness and blood pressure, the large SAVE trial did not show fewer major cardiovascular events in largely non‑sleepy patients with suboptimal adherence, underscoring that benefits track with hours of nightly use. Weight management is a powerful disease modifier; intensive lifestyle programs and, more recently, anti‑obesity pharmacotherapy (for example, tirzepatide) can substantially reduce AHI, sometimes independent of CPAP. Eastern and traditional perspectives frame OSA through different lenses but increasingly target similar mechanisms: collapsible airway, altered neuromuscular tone, and excess weight/kapha or phlegm‑damp accumulation. In Traditional Chinese Medicine (TCM), common patterns include phlegm‑dampness obstructing the oropharynx and spleen‑qi deficiency failing to transform fluids; treatment uses acupuncture (often with electroacupuncture) at local and systemic acu

Western Medicine
Diagnosis
Adult OSA is diagnosed with overnight polysomnography (PSG) or, in uncomplicated cases, home sleep apnea testing (HSAT). Severity is based on AHI: mild 5–14, moderate 15–29, severe ≥30 events/hour. Diagnosis may also consider symptoms (sleepiness, snoring, witnessed apneas) and comorbidities. PSG also characterizes sleep architecture, oxygen desaturations, arousals, and can titrate CPAP. Scoring follows AASM rules for apnea and hypopnea (3% desaturation and/or arousal, or 4% desaturation depending on lab/payer).
Treatments
- Positive airway pressure (PAP): CPAP/APAP as first‑line across severities; bilevel PAP in select cases
- Oral appliances: custom, titratable mandibular advancement devices (MADs) for mild‑to‑moderate OSA or CPAP‑intolerant patients
- Positional therapy: avoiding supine sleep via devices or training for position‑dependent OSA
- Weight management: intensive lifestyle intervention; consideration of anti‑obesity pharmacotherapy and bariatric surgery when indicated
- Surgical options: uvulopalatopharyngoplasty (UPPP) in selected anatomy; maxillomandibular advancement (MMA) for severe skeletal restriction; multilevel airway surgery as per DISE findings; hypoglossal nerve stimulation (Inspire) for CPAP‑intolerant moderate–severe OSA with appropriate anatomy
- Adjuncts: optimize nasal breathing (intranasal steroids for rhinitis, nasal dilators), alcohol/sedative reduction, exercise training
- Myofunctional/oropharyngeal exercises as adjuncts, especially in mild–moderate OSA or to aid residual AHI and snoring
Medications
- Wake‑promoting agents for residual sleepiness despite adequately treated OSA: modafinil, armodafinil, solriamfetol, pitolisant
- Intranasal corticosteroids for allergic rhinitis contributing to nasal obstruction
- Anti‑obesity pharmacotherapy for weight‑related OSA: GLP‑1 or GLP‑1/GIP receptor agonists (e.g., tirzepatide) in appropriate candidates
- Avoidance or deprescribing of respiratory depressants/sedative‑hypnotics where possible
Limitations
- CPAP effectiveness depends on adherence; mask discomfort, nasal symptoms, and claustrophobia can limit nightly use. - Oral appliances reduce but may not normalize AHI; dental side effects and variable efficacy require follow‑up sleep testing. - Positional therapy is less effective in non‑positional OSA and long‑term adherence can wane. - Surgical outcomes depend on anatomy and surgeon expertise; UPPP alone has variable success, whereas MMA and hypoglossal nerve stimulation have more predictable results in selected patients but involve cost and invasiveness. - The SAVE trial found no reduction in major cardiovascular events with CPAP in minimally sleepy, low‑adherence patients, highlighting the importance of patient selection and adherence. - Medications do not treat airway collapse itself (except weight‑loss agents that address a core driver); wake‑promoting drugs target residual sleepiness only and require safety monitoring.

Eastern & Traditional Medicine
Traditional Chinese Medicine (TCM)
OSA is commonly interpreted as phlegm‑dampness and turbidity obstructing the oropharynx with underlying spleen‑qi deficiency and, in some patients, kidney yang deficiency. Treatment seeks to transform phlegm, strengthen spleen qi, resolve dampness, and open the airway while supporting restorative sleep.
Techniques
- Acupuncture or electroacupuncture including local points for upper airway tone (e.g., LI18, ST9, SI17, Ren23) plus systemic points for phlegm/qi (e.g., ST36, SP6, ST40, LI4) individualized by pattern
- Auricular acupuncture as adjunct for snoring and sleep quality
- Chinese herbal formulas tailored to pattern (commonly used bases include Er Chen Tang for phlegm‑dampness; Ban Xia Hou Po Tang for ‘plum‑pit’ qi with throat globus; Ling Gui Zhu Gan Tang for phlegm‑fluid) with practitioner‑guided modifications
- Dietary therapy to reduce dampness (lower refined carbs/alcohol; warm, cooked foods) and promote weight loss
- Tuina and breathing/airway opening exercises as adjuncts
Ayurveda (including Yoga/Pranayama)
OSA is often viewed as a kapha‑dominant sleep disorder marked by heaviness, mucus accumulation, and reduced tone. Management emphasizes reducing kapha (weight reduction, light/spicy diet, metabolic activation), improving airway patency, and strengthening neuromuscular control with breath and posture practices.
Techniques
- Lifestyle and diet to reduce kapha: early, lighter dinners; limiting dairy, sweets, alcohol; daily activity
- Pranayama emphasizing nasal and diaphragmatic breathing (e.g., alternate‑nostril breathing/anulom‑vilom; gentle ujjayi; paced breathing) with caution to avoid hyperventilation practices if cardiovascular disease present
- Yogic postures that support weight control and respiratory mechanics (e.g., gentle backbends and thoracic openers)
- Nasal hygiene (jala neti/saline rinses) and, in some traditions, nasya oils under practitioner guidance for nasal patency
- Herbal support for weight management and glycemic control (used cautiously and with medical oversight), e.g., triphala, guggul—recognizing variable quality of evidence and potential drug–herb interactions
Orofacial Myofunctional Therapy (OMT) / Oropharyngeal Exercises
Targeted exercises retrain tongue, soft palate, and oropharyngeal muscles to reduce collapsibility and snoring. Though often delivered by dental or speech professionals, these programs overlap with eastern breathing disciplines through tongue posture and nasal‑diaphragmatic breathing emphasis.
Techniques
- Daily tongue and soft‑palate exercises; lip seal and nasal breathing training; chewing/swallowing pattern correction
- Adjunct devices or musical wind instrument training (e.g., didgeridoo) to condition upper‑airway muscles

Integrative Perspective
- Do not substitute complementary approaches for PAP in moderate–severe OSA. CPAP/APAP remains first‑line; alternatives are adjuncts unless a proven, equivalent therapy (e.g., custom mandibular advancement device in selected patients) is chosen with objective follow‑up testing. - Combine adherence optimization (mask fitting, humidification, nasal care) with daytime oropharyngeal/myofunctional exercises; this pairing can improve residual snoring/AHI and patient satisfaction. - Layer weight management across all severities: structured lifestyle change, exercise training, and when indicated, anti‑obesity pharmacotherapy (e.g., GLP‑1/GIP agonists) or bariatric surgery. Weight loss synergizes with PAP and oral appliances and can downstage disease. - Incorporate low‑risk breathing practices (nasal, diaphragmatic, paced breathing) and positional strategies; ensure no delay in definitive therapy. - For patients with nasal obstruction or allergic rhinitis, integrate intranasal steroids/saline irrigation with TCM or Ayurvedic nasal hygiene to improve PAP tolerance. - Always re‑check objective efficacy (repeat HSAT/PSG) after any non‑PAP intervention or combination therapy to ensure adequate control of respiratory events.
