Sleep disorder · Brussels

Understanding and treating snoring.

Snoring is common and often harmless, but it can also be a sign of sleep apnoea. At the CIRCAE sleep centre in Woluwe-Saint-Lambert (Brussels), a sleep physician looks for an underlying cause and offers the right treatment, from a mandibular advancement device to sleep-hygiene measures.

Understanding

Why do we snore?

Snoring is produced by the vibration of the soft tissues of the throat (soft palate, uvula, base of the tongue) as air passes during sleep, when the airway narrows. Excess weight, evening alcohol, sleeping on the back, nasal congestion or age-related muscle relaxation all make it more likely.

Simple snoring is mainly disturbing for those nearby. But when it comes with breathing pauses, fatigue and sleepiness, it can reveal sleep apnoea, which it is important to screen for. That is why the first step is always to rule out apnoea.

The solutions

Treating snoring

Depending on the cause and whether apnoea is present, several solutions exist.

Lifestyle measures

First step

Weight loss, less evening alcohol, stopping smoking, sleep position and treating nasal congestion.

Mandibular advancement device

Snoring & mild apnoea

A custom-made oral device that gently advances the jaw to open the airway and reduce snoring.

Apnoea treatment (CPAP)

If apnoea present

When sleep apnoea is confirmed, continuous positive airway pressure (CPAP) eliminates both the apnoeas and the snoring.

Screening

First, rule out apnoea

Before treating snoring, a sleep recording confirms there is no apnoea. See the CIRCASLEEP sleep assessment →

First sleep consultation

Consultation · Doctor + Neuropsychologist

A meeting with two sleep experts to assess the type of disorder and the need for an in-depth assessment.

  • Analysis of your symptoms (fatigue, sleepiness, insomnia, snoring, night-time awakenings)
  • Assessment of medical history, treatments and sleep hygiene
  • Identification of behavioural, psychological and medical factors
  • Referral to the most relevant sleep examination
  • Initial personalised care

Overnight oximetry: O2Fellow

Home examination · Non-invasive

A simple examination carried out at home using a discreet finger ring. It assesses overnight desaturations and the cardiovascular risk associated with apnoea.

  • Oxygen saturation (SpO₂)
  • Heart rate and pulse wave
  • Hypoxic burden: a key indicator of cardiovascular risk

Objectives

  • Detect overnight desaturations
  • Estimate cardiovascular risk
  • Refer to a more comprehensive examination if necessary

Overnight polygraphy

Home examination · Respiratory

Recording of respiratory and cardiac parameters during sleep. Primarily intended for the screening of obstructive sleep apnoea.

  • Respiratory airflow (nasal and oral)
  • Thoracic and abdominal effort
  • Oxygen saturation, heart rate
  • Snoring and body position

Objectives

  • Screen for mild to severe apnoea
  • Quantify apnoeas and hypopnoeas
  • Monitor the effectiveness of CPAP or oral appliance treatment

Full polysomnography

Gold-standard examination · Comprehensive

The most comprehensive sleep examination. It accurately diagnoses respiratory disorders, severe insomnia, parasomnias and restless legs syndrome.

  • EEG brain activity: sleep stages
  • Eye movements (EOG) and muscle activity (EMG)
  • Breathing, saturation, heart rhythm (ECG)
  • Snoring and body position

Results

  • A report including total duration, sleep stages, apnoea/hypopnoea index (AHI), saturation and hypoxic burden
The treatments

Validated and personalised solutions

CIRCASLEEP combines the gold-standard non-pharmacological and medical treatments, prescribed and monitored by our team.

CBT-I therapy

Gold-standard treatment · Chronic insomnia

Cognitive behavioural therapy for insomnia. A structured programme of 6 to 8 individual or group sessions (45–60 min) aimed at restoring natural sleep without dependence on sleeping pills.

CPAP

Gold-standard treatment · Moderate to severe apnoea

Delivers pressurised air during sleep to keep the airways open. Eliminates apnoeas and reduces snoring and cardiovascular risk.

Mandibular advancement device (MAD)

Oral appliance · Snoring & mild to moderate apnoea

The Oniris+ device holds the lower jaw forward to prevent airway obstruction. Thermo-mouldable, adjustable and comfortable.

Light therapy · AYO

Non-pharmacological approach · Circadian rhythm

AYO glasses emit controlled blue light (20 min/day in the morning). The AYO+ models combine stimulating blue light and relaxing red light to regulate the body clock.
