Snoring is the most prominent symptom of OAS (Obstructive Sleep Apnea Syndrome). It’s the sound produced during sleep by the vibration of secretions on the edge of the pharyngeal mucosa caused by airflow passing through the upper respiratory tract.
Snoring with a loudness below 60 dB is often considered normal. However, snoring does not necessarily indicate OHSAS.
Does a CPAP machine stop snoring? Most snorers don’t need a CPAP machine. While CPAP devices can often resolve snoring, they are generally only recommended for people with sleep apnea.
For patients with OAS, snoring is a symptom of sleep apnea. However, most people who snore do not have sleep apnea, but rather experience breathing difficulties due to other reasons such as nasal congestion or nasal polyps. These individuals can usually reduce snoring by improving their lifestyle or through other treatments.
Can Snoring Occur Without Sleep Apnea?
Snoring is one of the main symptoms of obstructive sleep apnea, but it is also common to snore without sleep apnea.
Snoring is usually caused by narrowing of the throat or nasal cavity, resulting in restricted airflow.
Smoking, obesity, chronic rhinitis, nasal polyps, and alcohol consumption are all contributing factors. Mild snoring generally does not cause sleep apnea.
We categorize snoring into simple snoring and obstructive sleep apnea. The former is common and requires no treatment; the latter involves pauses or hypopnea between snoring sounds at night, which is harmful to health and requires attention.
Is It Snoring Or Sleep Apnea?
We can make a comprehensive judgment based on the following three aspects to see if our snoring is sleep apnea.
Symptom
The most characteristic symptoms of sleep apnea are uneven snoring and excessive daytime sleepiness. The most common symptom is dry mouth upon waking, while other symptoms include loud snoring, being woken up gasping for air during sleep, or being discovered by a roommate to be holding their breath during sleep.
(1) Uneven snoring refers to recurring, intermittent snoring lasting 1-2 minutes. A typical symptom is a sudden, loud snoring sound after a few seconds or tens of seconds of silence, which then weakens.
However, if you don’t snore when sleeping on your side but snore when sleeping on your back, then it’s not considered uneven snoring.
(2) People with sleep apnea experience poor sleep quality, manifesting as falling asleep quickly, excessive daytime sleepiness, or headaches and dizziness.
Falling asleep quickly can easily be mistaken for good sleep quality; while excessive daytime sleepiness strongly suggests sleep apnea, it’s not a symptom in all patients, occurring in only about one-fifth.
Some also experience a tight, heavy feeling in their head upon waking, as if they haven’t slept well, even if they’ve had a considerable amount of sleep, feeling as if they’ve stayed up all night.
(3) Some people are awakened by shortness of breath during sleep, or their breathing stops during sleep, by family members; these symptoms strongly suggest sleep apnea.
However, waking up gasping for air can also be caused by heart failure, bronchial asthma, anxiety, laryngospasm, and other conditions, requiring professional medical evaluation.
Almost every sleep apnea patient experiences dry mouth upon waking, and some symptoms are easily overlooked, such as increased urination at night and frequent dreams. However, these symptoms can also occur in other diseases and do not necessarily indicate sleep apnea.
Main Causes
Sleep apnea patients often have obesity or maxillofacial structure problems, manifesting as obesity, a short jaw, a thick neck, and an increased waist circumference. They are also prone to co-existing conditions such as rhinitis, tonsillitis, and gastroesophageal reflux.
Women are more susceptible to sleep apnea during menopause or postmenopause. Smokers and drinkers are more likely to develop sleep apnea. Generally speaking, the more risk factors present, the greater the probability of developing sleep apnea.
Comorbidities
Of the diseases that sleep apnea can cause, hypertension is probably the most thoroughly studied.
Hypertension patients, especially young patients, should be tested for sleep apnea regardless of whether they snore or experience daytime sleepiness, as sleep apnea is one of the most common causes of hypertension.
Sleep apnea is also a high-risk factor for many cardiovascular and metabolic diseases, such as heart failure, coronary heart disease, arrhythmia, stroke, erectile dysfunction, and diabetes.
Furthermore, sleep apnea can lead to poor concentration, memory loss, and decreased alertness. Depression and anxiety are significantly more common among patients with sleep apnea.
The above three aspects provide clues for discovering sleep apnea. Clinically, the possibility of sleep apnea can also be determined through questionnaires, such as the STOPBANG questionnaire, which is widely used to assess the possibility of obstructive sleep apnea.
Does a CPAP Machine Stop Snoring?
CPAP machines can effectively reduce or eliminate snoring and sleep apnea, especially for patients with obstructive sleep apnea.
CPAP machines maintain an open airway by providing a continuous positive airway pressure, preventing upper airway collapse and thus reducing or eliminating snoring and sleep apnea.
CPAP machines are suitable for most patients with obstructive sleep apnea (OSA).
Studies have shown that approximately 70-90% of OSA patients experience significant symptom improvement after using CPAP, including a reduction in apnea and hypopnea events, improved blood oxygen saturation, reduced daytime sleepiness, and improved quality of life.
CPAP machines can immediately improve breathing, often including a significant reduction in snoring. However, doctors rarely prescribe CPAP machines to people who snore but do not have sleep apnea.
While CPAP machines are highly effective, they are not suitable for all snorers. For non-obstructive snoring, such as that caused by nasal structural problems or laryngeal relaxation, the effectiveness of CPAP machines may be limited.
In such cases, other treatments may be necessary, such as orthodontic appliances, surgery, or lifestyle modifications (such as weight loss, avoiding alcohol, and certain medications).
Before using CPAP, patients should undergo a comprehensive evaluation and diagnosis to determine if they have obstructive sleep apnea (OSA) and whether CPAP treatment is appropriate.
Treatment Of Snoring
CPAP is rarely used to treat snoring in people without sleep apnea. Other methods are generally used to treat snoring, and effective treatments for snoring include lifestyle modifications, physical therapy, medication, and surgery.
General Treatment For Snoring
Patients can relieve snoring by improving their lifestyle and sleeping habits:
Lose weight: Obese people need to lose weight to reduce the airway narrowing caused by fat in the throat. Although reducing excess fat may not cure snoring, it usually relieves the symptoms of snoring.
Quit smoking: Quitting smoking can reduce airway inflammation or swelling and improve airway narrowing.
Limit alcohol: Avoid drinking before going to bed and avoid drinking large amounts of alcohol for a long time. This is important.
Sleeping on the side instead of lying on the back: Although snoring will occur regardless of sleeping position, when snoring is severe, if it is mild to moderate snoring, snoring is more likely when lying on the back, and lying on the side can help reduce snoring.
Avoid using too high pillows: You can raise the head of the bed appropriately to put the head and neck in a position with a clear airway, which can help relieve snoring.
Avoid taking sedatives (such as sleeping pills) before going to bed to avoid aggravating snoring.
Professional Treatment For Snoring
Surgical treatment: Surgical treatment is the primary treatment for obstructive sleep apnea-hypopnea syndrome in children. Surgical procedures include tonsillectomy or adenoidectomy.
For adult patients, if there are significant anatomical problems, surgery can be performed to widen the airway, thus providing effective treatment. The specific surgical procedure varies depending on the location of the obstruction or narrowing; the most common is uvulopalatopharyngoplasty.
If the soft palate or uvula is too long, excess soft tissue and fat can be surgically removed to widen and reshape the pharyngeal cavity.
Mandibular deformity: For cases of malocclusion or jaw development problems caused by prolonged mouth breathing in children, dentists can reduce snoring through orthodontic treatment.
Specifically, this involves wearing braces to help improve upper airway ventilation and facilitate smoother breathing.
Nasal congestion: Treating the underlying cause of nasal congestion, such as colds or allergic rhinitis, can be helpful. Over-the-counter medications can be used to relieve congestion and clear the nasal passages, such as decongestants and corticosteroid nasal sprays.
Deviated nasal septum, nasal polyps, and turbinate hypertrophy: Nasal surgeries such as septoplasty and polyp removal can correct abnormal nasal structures and improve nasal ventilation.
Tips To Prevent Snoring
- Strengthen physical exercise and maintain good living habits.
Avoid smoking and drinking, because smoking can cause respiratory symptoms to worsen, and drinking can aggravate snoring, nocturnal breathing disorders, and hypoxemia. Especially drinking before going to bed.
For obese people, they should actively lose weight and increase exercise.
Snoring patients often have decreased blood oxygen content, so they are often accompanied by high blood pressure, heart rhythm disorders, increased blood viscosity, increased heart burden, and easily lead to cardiovascular and cerebrovascular diseases. Therefore, it is necessary to pay attention to blood pressure monitoring and take antihypertensive drugs on time.
Do not take sedatives or sleeping pills before going to bed to avoid aggravating the inhibition of respiratory center regulation.
Sleep in a side-lying position, especially the right side, to avoid the tongue, soft palate, and uvula from relaxing and falling back during sleep, which will aggravate upper airway obstruction.
Postoperative patients should eat soft food and avoid overly hot food. Avoid strenuous activities.
Choose an appropriate pillow. Some people think that raising the pillow can help improve breathing. In fact, doing so has the opposite effect. It is recommended to choose a softer, more elastic, and appropriately high pillow to facilitate smooth breathing.
Do not drink alcohol before going to bed. Drinking alcohol before going to bed will increase blood sugar and blood pressure, narrow the respiratory tract, make breathing difficult, and cause snoring.
Use a humidifier to keep the air in the bedroom moist to avoid a dry throat and mouth.
Eat some honey before going to bed. Honey helps lubricate the throat and unclog the respiratory tract. So you can add some honey to the soothing tea you drink before going to bed to prevent snoring.
Exercise properly. Maintain healthy living habits, strengthen exercise, lose weight appropriately, and keep in good shape. These will help solve the snoring problem that bothers sleep and quality of life.
Conclusion
Snoring is one of the main symptoms of obstructive sleep apnea (OSA), but not everyone who snores has sleep apnea syndrome. While CPAP machines can effectively reduce or eliminate snoring and apnea, they are not recommended for people without sleep apnea.
Snoring can be alleviated through some common treatments. However, if the cause of snoring is diagnosed as sleep apnea, specialized treatments such as surgery and medication can be used.
