Loud snoring — causes and when to see a doctor
Snoring is the sound produced when soft tissues in the upper airway vibrate during sleep. Many people consider it harmless or merely a “partner annoyance” — but loud snoring is often the first sign of something more serious: obstructive sleep apnea (OSA). The difference between “ordinary snoring” and sleep apnea is not always obvious to a layperson.
What is snoring
Snoring occurs when air passes through a narrowed airway and causes vibration of the soft palate, tongue, tonsils, or pharyngeal walls. The narrowing can be due to relaxed musculature (normal during sleep), obesity, anatomic factors, or a combination.
We distinguish:
- Primary snoring — without breathing pauses or signs of apnea. Disturbs the partner but doesn’t harm health.
- Obstructive sleep apnea (OSA) — with breathing pauses and drops in oxygen saturation. A serious condition.
Most common causes of loud snoring
Anatomic factors
- Deviated septum and other obstacles to nasal breathing
- Enlarged tonsils and adenoids
- A low-hanging soft palate and elongated uvula
- Micrognathia (small lower jaw) or retrognathia (recessed jaw)
- Large tongue (macroglossia) or fatty tissue in the tongue region
Lifestyle factors
- Obesity — the leading reversible risk; reducing BMI often reduces or eliminates snoring
- Alcohol consumption before bed (relaxes the pharyngeal musculature)
- Smoking (chronic mucosal inflammation)
- Sleeping on the back (gravity pulls the tongue backward)
- Sedatives and sleep medications

⚠️ When snoring signals a serious condition
If your loud snoring is accompanied by these signs — see an ENT specialist:
- Your partner has noticed breathing pauses or gasping during sleep
- You wake up tired even after 7–8 hours of sleep
- You often doze off during the day (at work, watching TV, driving)
- Waking up with a headache or dry mouth
- Drug-resistant high blood pressure
- Arrhythmias, palpitations at night
- BMI greater than 30 + snoring
Diagnostics
To distinguish primary snoring from sleep apnea and precisely locate the obstruction, we use:
- STOP-BANG screening — initial filter for OSA risk
- ENT exam with focus on the nose, pharynx, tonsils, soft palate
- Endoscopic exam of the nose and pharynx — shows where the narrowing is
- DISE — drug-induced sleep endoscopy — endoscopy during controlled sleep. This is the only way to see exactly what happens when the patient is asleep and where the airway collapses. A routine awake exam cannot show this.
- Polysomnography (PSG) — when sleep apnea is suspected, we refer for PSG, which captures the complete sleep profile
Treatment
Conservative
Change of sleep position (side instead of back), weight loss, stopping alcohol before bed, treating nasal obstruction, mandibular advancement device that brings the lower jaw forward.
CPAP
The standard for moderate-to-severe OSA — a device that delivers air under pressure through a mask, keeping the airway open during sleep. Not used for primary snoring.
Surgical treatment
Considered after a DISE exam that identifies the mechanism of obstruction:
- Septoplasty + turbinate reduction — when nasal obstruction is the main problem
- Uvulopalatoplasty / palatoplasty — shortening and reshaping the soft palate and uvula
- Tonsillectomy — when enlarged tonsils are the main cause
- Multilevel surgery — combined procedures when obstruction is at multiple sites
💡 What you can do right now
- Take the STOP-BANG questionnaire (link above)
- Make a short recording of your snoring (the SnoreLab app is free)
- If you are the partner — note any breathing pauses you observe
- Try changing position and reducing alcohol before bed
- Don’t ignore it — untreated sleep apnea raises the risk of heart attack, stroke, and diabetes
