Snoring & Obstructive Sleep Apnoea (OSA)

Snoring is the rattling or grumbling sound that happens when relaxed throat tissues vibrate as air passes during sleep. It’s usually harmless but if it’s loud or frequent, it may signal obstructive sleep apnoea (OSA)

OSA occurs when your upper airway collapses during sleep, leading to partial or complete pauses in breathing. These interruptions can lower your oxygen levels and place stress on your heart.

Symptoms, Causes & Risk Factors

You or your sleep partner might notice:

Loud, chronic snoring
Gasping or choking sounds during sleep
Pauses in breathing
Restless sleep or frequent waking
Daytime sleepiness or fatigue
Morning headaches or dry mouth

Possible Causes & Risk Factors

Snoring and OSA can arise from a mix of anatomical and lifestyle factors:

Anatomy & Structure

Excess throat tissue from weight gain, enlarged tonsils, or a long soft palate/uvula
Nasal issues like congestion, a deviated septum, or polyps

Lifestyle Influences

Sleeping on your back (gravity narrows the airway)
Alcohol or sedative use that relaxes throat muscles
Sleep deprivation deepening muscle relaxation

Other Risk Factors

Excess neck weight from obesity
Family history of snoring or OSA

Diagnosis

To confirm OSA, specialists often recommend:

Flexible Nasoendoscopy

To pinpoint the blockage site (e.g., nose, tonsils, tongue base)
Overnight Sleep Study

(at home or in a clinic) to monitor breathing patterns and oxygen levels

Treatment Options

1. Lifestyle Adjustments

Simple yet effective changes include:

2. Oral Appliances (e.g. MAD)

Custom-made devices that gently shift the lower jaw forward to keep your airway clear, often used for mild to moderate cases or when CPAP isn’t tolerated

3. CPAP / Breathing Devices

CPAP: Delivers steady air pressure via a mask to keep the airway open—commonly effective but may require adaptation
BiPAP / Auto-Sleep Devices: Provide variable pressure for easier breathing, especially in severe or complicated cases

4. Surgical Interventions

Surgery may be recommended for anatomical obstructions when other methods fall short:

Nasal Procedures: Septoplasty or turbinate reduction to improve airflow
Throat Surgeries:
– Uvulopalatopharyngoplasty (UPPP) — removes small throat tissues to widen the airway
– Tongue base reduction or maxillomandibular advancement—repositions structures to prevent collapse
Hypoglossal Nerve Stimulation (e.g., Inspire®) — an implant that activates tongue movement during sleep; suited for moderate to severe OSA patients non-responsive to CPAP

5. What Comes Next?

Recovery varies:

Lifestyle tweaks are ongoing
CPAP or oral appliances require regular use and adjustment
Surgical recovery depends on the procedure—follow-up care helps optimize outcomes

Frequently Asked Questions

How do I know if I have OSA?

Signs include loud snoring, choking/gasping at night, and daytime sleepiness. A sleep study offers a definite answer

Is OSA dangerous if untreated?

Yes. OSA can raise risks for high blood pressure, heart disease, stroke, and daytime accidents

Can lifestyle changes make a difference?

Absolutely. weight loss, changing sleep position, and avoiding alcohol can significantly reduce symptoms

What if I can’t tolerate CPAP?

Oral appliances or Inspire® devices can be alternatives when CPAP isn’t suitable

Is surgery a cure?

It can help when non-surgical approaches fail—but suitability depends on your anatomy and diagnosis

Do snoring and OSA ever go away naturally?

OSA doesn’t resolve on its own. Treatments help manage symptoms and prevent complications
