Why Side-Sleeping Stops Some People’s Snoring (But Not Everyone’s) | Ueno Snoring Clinic
Where to See a Doctor for Snoring and Sleep Apnea in Tokyo: A Guide for Foreign Patients
“What kind of symptoms does a sleep disorder specialty clinic actually treat?”
“Is it okay to see a sleep disorder specialist for snoring or sleep apnea?”
“I’ve heard insomnia is handled by psychiatry, and children’s sleep issues by pediatrics — what’s the actual difference?”
Because sleep-related symptoms cover such a wide range, it can be genuinely confusing to know which type of clinic to visit.
A sleep disorder specialty clinic treats symptoms and conditions related to sleep. However, not every clinic that uses this label treats every type of sleep disorder.
At Ueno Snoring Clinic, we specifically focus on snoring, sleep apnea syndrome, and breathing disorders during sleep, which is why we describe ourselves as a “sleep disorder specialty clinic” in that specific sense.
We provide a full range of care under national health insurance — sleep testing, CPAP treatment, and lifestyle guidance — along with self-pay options such as laser snoring treatment and medically supervised weight-loss support, depending on your condition.
In this article, we explain what a sleep disorder specialty clinic actually covers, which type of clinic is right for different symptoms, and exactly which sleep disorders Ueno Snoring Clinic specializes in.
Ueno Snoring Clinic offers a range of options tailored to each patient’s condition, including insurance-covered sleep testing and CPAP management, as well as self-pay laser treatment for snoring. If you’d like to find out which treatment is right for you, please book an initial consultation.

What Is a Sleep Disorder Specialty Clinic?
A sleep disorder specialty clinic is an internal medicine department that treats symptoms and conditions related to sleep.
The term “sleep disorder” doesn’t just refer to being unable to fall asleep.
It covers a broad range of sleep-related conditions, including:
- Sleep apnea syndrome
- Insomnia
- Hypersomnia
- Narcolepsy
- Circadian rhythm sleep-wake disorders
- Restless legs syndrome
- REM sleep behavior disorder
- Sleep-related movement disorders
- Sleep disorders in children
On the Classification of Sleep Disorders (ICSD-3: International Classification of Sleep Disorders, 3rd Edition[1])
Sleep disorders are classified by the American Academy of Sleep Medicine (AASM) into the following main categories under the ICSD-3:
· Insomnia
· Sleep-related breathing disorders (including sleep apnea syndrome)
· Central disorders of hypersomnolence (including narcolepsy)
· Circadian rhythm sleep-wake disorders
· Parasomnias (including REM sleep behavior disorder)
· Sleep-related movement disorders (including restless legs syndrome)
Which of these categories a given medical facility specializes in varies by institution. Ueno Snoring Clinic specializes specifically in “sleep-related breathing disorders.”
Because sleep disorders cover such a broad range of conditions, areas of specialization vary significantly between medical facilities.
Even among clinics labeled “sleep disorder medicine,” some focus primarily on insomnia, while others focus primarily on sleep apnea syndrome and CPAP management.
Before your first visit, it’s worth confirming that the clinic you’re considering actually treats your specific symptoms.
What Does a Sleep Disorder Specialty Clinic Actually Treat?
When people hear “sleep disorder clinic,” they often assume it’s for people who can’t fall asleep — but that specific issue falls under “insomnia disorder,” which typically points toward a sleep-focused psychiatry clinic. A sleep disorder internal medicine clinic, by contrast, is generally for people who can fall asleep, but whose “sleep quality” is compromised.
Symptoms handled by a sleep disorder internal medicine clinic include:
- Loud snoring
- Pauses in breathing during sleep
- Waking up tired no matter how much you sleep
- Morning headaches
- Strong daytime sleepiness
- Frequent nighttime urination
- Difficulty falling asleep
- Waking up repeatedly during the night
- Waking up too early in the morning
- A reversed day-night sleep schedule
- Shouting or vocalizing during sleep
- Restless legs preventing sleep
That said, the same term — “sleep disorder” — can stem from very different underlying causes.
For example, someone who can’t sleep due to anxiety, depression, or psychological stress requires a very different evaluation and treatment approach than someone who’s being repeatedly woken by sleep apnea.
Which Type of Clinic Should You Visit, Based on Your Symptoms?
| Primary Symptom / Condition | Example Facility Type | Typical Focus of Care |
|---|---|---|
| Loud snoring / apnea | Sleep disorder internal medicine, pulmonology, ENT | Sleep testing, CPAP, airway evaluation |
| CPAP treatment & management | Sleep disorder internal medicine, pulmonology | Reviewing CPAP data, settings, and mask fit |
| Insomnia | Sleep-focused psychiatry, psychiatry, psychosomatic medicine, sleep clinics | Evaluating psychological state, sleep habits, and medication |
| Snoring / apnea in children | Pediatric sleep specialists, pediatrics, ENT | Evaluating tonsils/adenoids, development, and breathing |
| Narcolepsy / hypersomnia | Sleep specialty clinics, neurology, psychiatry | Evaluating daytime sleepiness, sleep testing, medication |
| REM sleep behavior disorder | Neurology, sleep specialty clinics | Evaluating abnormal behavior during sleep and neurological conditions |
The scope of care varies from facility to facility.
Rather than judging solely by the name “sleep disorder clinic,” it’s worth confirming which specific sleep disorders a given facility actually specializes in.
For Insomnia, a Sleep-Focused Psychiatry or Psychiatric Clinic May Be More Appropriate
Difficulty falling asleep, frequent nighttime waking, and waking too early can stem from a wide range of causes.
Psychological stress, anxiety, depression, disrupted daily rhythms, medication, and underlying physical conditions can all play a role.
In particular, evaluation at a sleep-focused psychiatry clinic, psychiatrist, or psychosomatic medicine specialist may be more appropriate if you’re experiencing:
- Significant anxiety or low mood
- Racing thoughts that prevent sleep
- A need to adjust sleep medication
- Panic symptoms or intense tension
- Symptoms that seem tied to stress from work or relationships
- An ongoing reversed day-night schedule
On the other hand, “waking up repeatedly during the night” can sometimes be caused by arousal responses triggered by sleep apnea.
If you also experience loud snoring, apnea, morning headaches, or daytime sleepiness, it’s worth having your breathing during sleep evaluated as well.
For Children, Visit a Pediatric Sleep Specialist, Pediatrician, or ENT
Sleep disorders in children often have different causes and treatments than in adults.
Snoring or sleep apnea in children can be related to enlarged tonsils, enlarged adenoids, nasal congestion, allergic rhinitis, or jaw development.
Sleep apnea in children may also present less as daytime sleepiness and more as restlessness, poor concentration, effects on learning, or bedwetting.
If you’re concerned about your child’s snoring or apnea, please see a pediatric sleep specialist, pediatrician, or ENT specialist equipped to evaluate symptoms appropriate to their age.
Important: Ueno Snoring Clinic focuses primarily on snoring and sleep apnea syndrome in adults. For children’s sleep disorders, we may refer you to a pediatrician or ENT specialist depending on the symptoms involved.
Why Ueno Snoring Clinic Uses the Term “Sleep Disorder Specialty Clinic”
Among the many types of sleep disorders, Ueno Snoring Clinic specializes specifically in sleep apnea syndrome and snoring.
Sleep apnea syndrome is a condition in which the airway narrows repeatedly during sleep, causing repeated episodes of apnea or hypopnea.
This leads to drops in oxygen and arousal responses during sleep, which in turn can cause sleep disorders such as:
- Inability to reach deep sleep
- Repeated nighttime waking
- Waking up tired despite sleeping
- Morning headaches
- Strong daytime sleepiness
- Reduced concentration and judgment
- Increased nighttime urination
In other words, sleep apnea syndrome isn’t simply “a snoring problem” — it’s one of the most significant sleep disorders in terms of degrading overall sleep quality.
Our clinic uses the term “sleep disorder specialty clinic” specifically to describe our role in testing for and treating this kind of breathing disorder during sleep.
We Specialize in Sleep Disorders Caused by Sleep Apnea Syndrome
Ueno Snoring Clinic is not a facility that specializes in every type of sleep disorder, such as insomnia, narcolepsy, or REM sleep behavior disorder.
What we specifically specialize in is breathing-related sleep disorders, including:
- Sleep apnea syndrome
- Loud snoring
- Sleep disorders accompanied by apnea
- Snoring caused by mouth breathing or nasal congestion
- Apnea related to obesity or tongue-base collapse
- Sleep disorders requiring CPAP treatment
- Snoring caused by soft palate vibration
Symptoms like “I never feel rested no matter how much I sleep” or “I wake up repeatedly during the night” are sometimes actually caused by sleep apnea syndrome.
For that reason, our clinic focuses not just on reducing the sound of snoring, but on evaluating your breathing during sleep and identifying the true underlying cause of your sleep disorder.
Sleep Testing Available at Ueno Snoring Clinic
The severity of sleep apnea syndrome cannot be accurately determined through a consultation or physical appearance alone.
Our clinic offers both a home sleep test and a full PSG test, both covered under national health insurance.
Home Sleep Test
This test involves wearing a small monitoring device at home while you sleep.
It primarily evaluates:
- The number of apnea/hypopnea events per hour
- Blood oxygen levels during sleep
- Changes in pulse rate
- Snoring intensity
- Airflow patterns
- Changes based on sleep position
PSG (Polysomnography)
PSG provides a more detailed evaluation of your sleep than a home sleep test.
It assesses sleep stages, brain waves, breathing patterns, oxygen levels, and body movement, giving a detailed picture of the severity of sleep apnea syndrome.
Based on the results, we discuss options such as CPAP, lifestyle guidance, positional therapy, oral appliances, or laser treatment.
Want to Get a Sleep Test?
If you experience loud snoring, apnea, morning headaches, or daytime sleepiness, sleep apnea syndrome may be behind it. At Ueno Snoring Clinic, evaluation can start with a home sleep test.
CPAP Treatment & Ongoing Management
For moderate-to-severe sleep apnea syndrome, CPAP is one of the standard treatments.
CPAP delivers air through a mask during sleep, using air pressure to keep the airway from collapsing.
At our clinic, we don’t just get you started on CPAP — we provide ongoing management, including:
- Reviewing hours of CPAP use
- Checking residual AHI
- Checking mask leak
- Evaluating pressure settings
- Discussing mask discomfort
- Addressing nasal congestion and dry mouth
- Guidance for using CPAP while traveling
Starting CPAP isn’t the end of the process.
What matters is continuously reviewing treatment data and adjusting your setup so it’s genuinely sustainable for you long-term.
Finding CPAP Follow-Up Visits Difficult to Manage?
Ueno Snoring Clinic offers online consultations for patients currently on CPAP therapy. If monthly or bi-monthly in-person visits are a burden, please check whether you’re eligible.
Lifestyle Guidance Is Also Part of Sleep Apnea Treatment
Sleep apnea syndrome can be worsened not just by throat structure, but by lifestyle habits as well.
Depending on your test results and consultation, we may offer guidance such as:
- Avoiding alcohol before bed
- Managing your weight
- Adopting side-sleeping
- Getting adequate sleep duration
- Not leaving nasal congestion untreated
- Reviewing smoking habits and late-night eating
- Using CPAP for the entire duration of sleep
For patients with mild symptoms, adjusting lifestyle habits and sleep position alone can sometimes improve snoring and apnea.
For moderate-to-severe cases, however, lifestyle guidance alone is often insufficient, and is combined with treatments such as CPAP.
We Also Offer Laser Snoring Treatment
Ueno Snoring Clinic offers laser snoring treatment for patients whose snoring is thought to be primarily driven by vibration in the soft palate and around the uvula.
Laser treatment applies thermal energy to the mucosal tissue of the throat, tightening the area around the soft palate to reduce the vibration that causes snoring.
That said, laser snoring treatment is not an effective treatment for every case of sleep apnea syndrome.
In cases involving tongue-base collapse, significant obesity, or severe sleep apnea syndrome, laser treatment alone may not provide sufficient improvement.
For this reason, even for patients requesting laser treatment specifically, we may recommend a sleep test as needed to confirm the severity of apnea before determining suitability.
Medically Supervised Weight-Loss Support Is Also an Option for Weight-Related Cases
Obesity is one of the most significant factors that worsens sleep apnea syndrome.
As fat accumulates around the neck, tongue, and throat, the airway becomes more prone to narrowing during sleep.
For patients whose weight appears to be contributing to their snoring or apnea, we may recommend lifestyle guidance or medically supervised weight-loss support.
That said, weight loss alone doesn’t always fully resolve apnea.
Depending on severity, managing weight alongside treatments such as CPAP is often the more effective approach.
We Don’t Simply Prescribe CPAP and Stop There
Treating sleep apnea syndrome requires more than reviewing test results — it requires identifying exactly where the airway is narrowing.
At Ueno Snoring Clinic, based on a throat examination and overall physical assessment, we evaluate factors such as:
- Drooping of the soft palate
- Vibration around the uvula
- Tongue size
- Possible tongue-base collapse
- Jaw size and positioning
- Nasal congestion and mouth breathing
- Neck circumference and body weight
- Alcohol use and sleep position
Based on this evaluation, we consider options such as sleep testing, CPAP, lifestyle guidance, laser treatment, and weight management to find the approach best suited to you.
Our goal isn’t to recommend a specific treatment.
It’s to identify the cause and severity of your snoring or apnea, and propose the treatment that’s genuinely right for you.
