Two things that sound identical at three in the morning
One is a noise. The other is a medical condition associated with hypertension, arrhythmia and stroke. They sound the same through a bedroom wall, and separating them is the single most useful thing a doctor can do for someone who snores.
Simple snoring is turbulent airflow vibrating the soft tissues at the back of the throat. It is disruptive, it strains relationships, and it is not in itself dangerous.
Obstructive sleep apnoea is the airway repeatedly closing during sleep, so breathing stops for seconds at a time, dozens or hundreds of times a night. Each pause drops blood oxygen and jolts the nervous system. Over years, that is associated with raised blood pressure, cardiac arrhythmia and increased stroke risk.
Roughly speaking, most people who snore do not have apnoea. But most people who have apnoea snore. Which is why the noise is worth investigating rather than simply silencing.
What the laser actually does
NightLase uses an Er:YAG laser in a mode designed to deliver heat without ablating tissue. It is applied to the soft palate and the tissue around the tonsils, warming the collagen there so it contracts and, over the following weeks, remodels.
Tighter tissue vibrates less. Less vibration, less noise.
The course is three sessions about a month apart, each roughly half an hour. No anaesthetic, no incision, no downtime. Most patients eat normally the same day and return to work immediately.
Note what that mechanism does not do. It tightens soft tissue. It does not widen a narrow airway, it does not move a jaw, it does not clear a blocked nose, and it does not reduce fat around the tongue base. If your problem is any of those, tightening the palate will disappoint you, and we would rather say so before you pay for three sessions.
What happens before we switch anything on
An assessment, and it is not a formality.
We ask about witnessed pauses in breathing, gasping or choking on waking, morning headaches, and whether sleep is unrefreshing however long you spend in bed. We ask your partner, who is usually the better historian. We measure neck circumference, because it predicts airway crowding more reliably than weight alone. We look at the nose, the palate, the tonsils and the tongue base, because the site of obstruction determines whether this treatment has anything to offer you.
And we ask about daytime sleepiness, specifically whether you have ever felt yourself losing the fight to stay awake at the wheel.
If the picture suggests apnoea, we refer you for a sleep study before considering any laser. That is the correct order and it is not negotiable. Silencing the snore of someone with untreated apnoea removes the one symptom that would have led them to a diagnosis, and that is a genuinely harmful outcome.
The part nobody wants to hear
Weight is the largest modifiable factor in both snoring and apnoea, and it is not close.
Fat deposits around the neck, the tongue base and the pharyngeal walls narrow the airway from the outside in. Lying down, the effect worsens. This is why snoring often begins in the same decade the weight does, why it is worse after a heavy meal or a few drinks, and why partners notice it first on the back rather than the side.
The evidence here is unusually clear. Meaningful weight loss reduces the severity of obstructive sleep apnoea, and in a proportion of patients with mild disease it resolves it. Neck circumference is the measure that tracks best, not the number on the scale, and a few centimetres there can change the airway more than any procedure.
So when weight is a contributing factor, our answer is not the laser alone. It is the laser, if the palate is genuinely the problem, running alongside a medical weight management programme with body composition tracked rather than guessed at. One addresses the noise. The other addresses why the airway narrowed in the first place.
That is a slower, less appealing sentence than "three sessions and it stops". It is also the honest one, and it is why the two sit under one roof here.
Who this suits, and who it does not
It suits someone whose snoring is palatal in origin, whose weight is stable and reasonable, who has been screened and does not have significant apnoea, and who wants a non-surgical option before considering anything more invasive.
It suits less well someone whose obstruction is nasal, who has significant tonsillar enlargement, whose jaw position is the underlying issue, or whose snoring is one symptom of untreated apnoea.
It does not suit anyone hoping to avoid a sleep study they have already been advised to have. We will say no to that, politely, every time.
What to expect, stated plainly
Improvement is usually partial rather than total. The realistic goal is a quieter night and a partner who sleeps through, not silence. Some patients report a change within days of the first session; for others it builds across the course as collagen remodels.
Reported benefit commonly lasts around a year, sometimes longer, and a maintenance session can be repeated when the snoring begins to return. It is a therapy that is managed rather than a problem that is cured, and anyone describing it otherwise is overstating it.
Outcomes vary between individuals and no result can be guaranteed. What we can promise is an honest assessment of whether you are likely to be one of the people it helps.
Frequently asked questions
For snoring caused by vibration of the soft palate, the published evidence reports meaningful reduction in snoring volume and frequency for most patients, with partners often noticing before the patient does. It works less well, or not at all, where the obstruction is nasal, structural, or driven by significant excess weight. Which of those you have is what the assessment determines.
No. It is a therapy for snoring. In obstructive sleep apnoea it may be used alongside other treatment under specialist care, but it does not replace CPAP or a surgical opinion, and treating the noise while leaving apnoea undiagnosed is the outcome we most want to avoid. Anyone with suspected apnoea is referred for a sleep study first.
Warning signs include pauses in breathing witnessed by a partner, gasping or choking on waking, unrefreshing sleep however long you spend in bed, morning headaches, and daytime sleepiness heavy enough to affect driving or work. A collar size above about 43cm in men or 40cm in women raises the likelihood. None of these is diagnostic on its own, which is why a sleep study exists.
Most patients describe a sensation of warmth at the back of the throat rather than pain. No anaesthetic is used and no incision is made. You can eat, speak and return to work immediately, though we suggest avoiding very hot food for a few hours.
Three sessions spaced about a month apart is the standard course. Some patients report improvement after the first. Reported benefit commonly lasts around a year, sometimes longer, and a single maintenance session can be repeated when snoring begins to return.
For many people it does more than any procedure. Fat deposited around the neck and tongue base narrows the airway, and studies of medical weight loss show substantial reductions in apnoea severity. It is slower and less appealing than a laser, and it treats the cause rather than the symptom. Where weight is a factor we would rather run both together than sell you the laser alone.
Discuss it with the specialist managing your apnoea. Some patients use laser therapy alongside CPAP to reduce residual snoring or improve tolerance. It is not a route to stopping CPAP, and we would not position it as one.
