Snoring versus sleep apnoea
Snoring is the sound of turbulent airflow through a narrowed upper airway. Many people snore without any health consequence. Obstructive sleep apnoea is different: the airway repeatedly collapses shut during sleep, breathing stops for seconds at a time, oxygen falls, and the brain briefly rouses to reopen the airway — dozens of times an hour, usually without the person ever remembering.
That is why sufferers can spend eight hours in bed and wake exhausted. The sleep is fragmented at a level they are not aware of.
Features that suggest apnoea rather than simple snoring
- Witnessed pauses in breathing, gasping or choking during sleep
- Loud snoring heard through a closed door
- Waking unrefreshed despite adequate hours in bed
- Daytime sleepiness — dozing while reading, watching television, in meetings, or at traffic stops
- Morning headache, dry mouth, night-time urination
- Irritability, poor concentration and memory difficulty
- High blood pressure, especially if difficult to control
Untreated obstructive sleep apnoea is associated with hypertension, cardiac arrhythmias, stroke, poor diabetic control and a substantially increased risk of road traffic accidents. This is the reason to take it seriously rather than the snoring itself.
How assessment works
Treatment fails when it is applied without identifying where the airway is obstructing. The obstruction may lie in the nose, at the soft palate and uvula, at the tonsils, or at the base of the tongue — and often at more than one level in the same patient. Surgery aimed at the wrong level will disappoint.
A proper evaluation includes
- Screening questionnaires — STOP-BANG for apnoea risk and the Epworth scale for daytime sleepiness give an objective starting point
- Full ENT airway examination, including nasal endoscopy, to identify septal deviation, turbinate enlargement, polyps, tonsil size, palate position and tongue base
- Sleep study (polysomnography) — the definitive test, which measures how often breathing stops and how far oxygen falls, and grades the severity
- Assessment of contributing factors — weight, alcohol and sedatives, sleeping position, nasal allergy, thyroid and jaw structure
Record your sleep symptoms before your visit
STOP-BANG is a standardised screening questionnaire for obstructive sleep apnoea risk. It is a screening tool, not a diagnosis. Your answers stay on your own device.

Non-surgical measures
These come first and matter more than patients expect. Weight reduction has a genuine, measurable effect on apnoea severity. Avoiding alcohol and sedatives in the evening, treating nasal allergy, and side-sleeping rather than back-sleeping all help. For established moderate to severe apnoea, CPAP — a mask delivering gentle air pressure that splints the airway open — remains the most effective treatment available and the benchmark against which everything else is measured.
Where surgery helps
Surgery is not an alternative to CPAP for everyone; it is the right answer for specific situations:
- Nasal surgery (septoplasty, turbinate reduction, polyp removal) — for patients whose nasal obstruction is severe. It improves symptoms and, importantly, often makes CPAP tolerable for those who could not use it because of a blocked nose
- Tonsil surgery — where large tonsils are clearly the obstructing level. Results depend on whether the tonsils are the main site of obstruction
- Palatal surgery — for obstruction at the level of the soft palate in appropriately selected patients
Being straightforward about this: no single operation cures all sleep apnoea. Results depend on correctly identifying the level of obstruction and selecting the right patient. A surgeon who offers one operation for every patient with snoring is not assessing the problem properly.
If you have fallen asleep or nearly done so while driving, or score in the severe range for daytime sleepiness, avoid driving until you have been assessed and treated. This is the single most immediate risk of untreated sleep apnoea.
കൂർക്കംവലിയും സ്ലീപ് അപ്നിയയും — ചുരുക്കത്തിൽ
എല്ലാ കൂർക്കംവലിയും അപകടകരമല്ല. എന്നാൽ ഉറക്കത്തിൽ ശ്വാസം നിലയ്ക്കുക, ശ്വാസംമുട്ടി ഞെട്ടിയുണരുക, എത്ര ഉറങ്ങിയാലും ക്ഷീണം മാറാതിരിക്കുക, പകൽ ഇരുന്നിടത്ത് ഉറങ്ങിപ്പോകുക — ഇവയുണ്ടെങ്കിൽ അത് ഒബ്സ്ട്രക്ടീവ് സ്ലീപ് അപ്നിയ ആകാം.
ചികിത്സിക്കാത്ത സ്ലീപ് അപ്നിയ ഉയർന്ന രക്തസമ്മർദ്ദം, ഹൃദ്രോഗം, പക്ഷാഘാതം, പ്രമേഹ നിയന്ത്രണക്കുറവ്, വാഹനാപകടങ്ങൾ എന്നിവയുമായി ബന്ധപ്പെട്ടിരിക്കുന്നു.
ചികിത്സ: ആദ്യം തടസ്സം എവിടെയാണെന്ന് കണ്ടെത്തണം — മൂക്ക്, അണ്ണാക്ക്, ടോൺസിൽ, നാവിന്റെ പിൻഭാഗം. ഭാരം കുറയ്ക്കൽ, മദ്യം ഒഴിവാക്കൽ, ഒരു വശം ചരിഞ്ഞ് കിടക്കൽ എന്നിവ സഹായിക്കും. മിതമായതും കഠിനവുമായ കേസുകളിൽ CPAP ആണ് ഏറ്റവും ഫലപ്രദം. ചില രോഗികളിൽ മൂക്ക്/ടോൺസിൽ ശസ്ത്രക്രിയ വലിയ മാറ്റമുണ്ടാക്കും.
ശ്രദ്ധിക്കുക: ഉറക്കംതൂങ്ങുമ്പോൾ വാഹനം ഓടിക്കരുത്.
Frequently asked questions
Is snoring always a sign of sleep apnoea?
No. Many people snore without any breathing obstruction or health consequence. Snoring becomes concerning when accompanied by witnessed pauses in breathing, gasping, waking unrefreshed, daytime sleepiness, morning headaches, or difficult-to-control blood pressure. A screening questionnaire and sleep study distinguish the two.
Do I need a sleep study before treatment?
For suspected obstructive sleep apnoea, yes. A sleep study measures how often breathing stops and how far oxygen levels fall, which grades severity and guides treatment. Snoring can be assessed clinically, but no treatment decision for apnoea should be made without objective measurement.
Can surgery cure sleep apnoea?
Sometimes, but not universally. In children with enlarged tonsils and adenoids, surgery addresses the commonest cause of obstruction, and outcomes are generally good. In adults, results depend entirely on correctly identifying the level of obstruction and selecting the right patient. For moderate to severe apnoea in adults, CPAP remains the most effective treatment, and surgery is often used to make CPAP tolerable or to treat a specific obstructing level.
Will nasal surgery stop my snoring?
It frequently improves snoring where nasal obstruction is a major factor, because a blocked nose forces mouth breathing. Its most valuable role, however, is enabling patients who could not tolerate CPAP because of a blocked nose to use it successfully.
Does losing weight really help sleep apnoea?
Yes, meaningfully. Weight reduction lowers the severity of obstructive sleep apnoea measurably and improves the results of every other treatment. It does not replace the need for assessment, but it is one of the few interventions entirely within the patient's control.
Is it safe to drive with untreated sleep apnoea?
Untreated obstructive sleep apnoea substantially increases the risk of road traffic accidents. If you have fallen asleep or nearly fallen asleep while driving, or have severe daytime sleepiness, avoid driving until you have been assessed and treated.
