Why Do We Snore? Sleep Apnea Symptoms and Treatment

Snoring is the sound produced when the upper airway narrows during sleep, and contrary to popular belief, it isn't always harmless. Severe and irregular snoring, in particular, is one of the primary symptoms of sleep apnea—a condition where breathing repeatedly stops and starts throughout the night. If left untreated, this deprives the body of oxygen and can lead to life-threatening risks such as heart attacks, high blood pressure, and strokes.

At a Glance:

• Snoring is a sign of airway narrowing, caused by the vibration of soft tissues in the respiratory tract.
• Sleep apnea occurs when breathing stops for more than 10 seconds, repeatedly throughout the night.
• Morning fatigue, headaches, and excessive daytime sleepiness are the most prominent warning signs.
• A definitive diagnosis is made using a sleep study called polysomnography, where the patient is monitored overnight.
• Depending on the patient's condition, treatment options include a CPAP machine, surgical intervention, or lifestyle changes.

What Are Snoring and Sleep Apnea?

During sleep, our muscles naturally relax. As air flows through a narrowed airway, it causes tissues like the soft palate, uvula, and tonsils to vibrate, producing the familiar sound of snoring. While snoring alone isn't a disease, it is a clear indication of a physical narrowing in the upper respiratory tract. Sleep apnea (specifically, Obstructive Sleep Apnea) occurs when this narrowing reaches a much more advanced stage, causing the airway to close completely or partially, which temporarily stops breathing.

When breathing stops, oxygen levels in the blood drop rapidly. To keep the body alive and restart breathing, the brain triggers a "micro-awakening." You usually won't remember these brief moments of waking up, but this cycle can repeat hundreds of times a night. Affecting millions of people, this condition prevents you from entering the deep, restorative stages of sleep. While it is particularly common among middle-aged and older men both in Türkiye and globally, it can also affect postmenopausal women and individuals of any age who struggle with weight issues.

What Causes Snoring?

The causes of snoring typically stem from a combination of anatomical structure, lifestyle, and age-related factors. One of the primary culprits behind a narrowed upper airway is a deviated septum (crooked cartilage and bone within the nose). Additionally, enlarged adenoids—often seen from childhood—large tonsils, a drooping soft palate, and an unusually long uvula can obstruct airflow and set the stage for snoring.

Excess weight and obesity increase the fatty tissue around the neck, which puts external pressure on the airway and directly intensifies snoring. Furthermore, consuming alcohol in the evening, taking muscle relaxants, and extreme fatigue can cause throat muscles to relax more than usual, narrowing the respiratory tract. Sleeping on your back is another common factor, as gravity causes the base of the tongue to fall backward, blocking the airway. As we age, throat muscles naturally lose their tone, which is why snoring becomes much more common in later years.

Symptoms and Risks of Sleep Apnea

Because sleep apnea symptoms primarily occur while a person is asleep, they are often noticed by a partner or family member sharing the room rather than the patient themselves. Loud, irregular snoring is the most obvious sign. The sudden cessation of snoring, followed by a period of silence (when breathing stops), and then a deep, noisy gasp for air is the classic cycle of an apnea episode.

The main symptoms of sleep apnea include:

• Frequent night sweats and restless tossing and turning in bed
• Waking up suddenly with a feeling of choking or gasping for air
• Waking up in the morning with a dry mouth, sore throat, and severe headache
• Constant daytime fatigue, lethargy, and a tendency to doze off (such as while watching TV or in traffic)
• Distractibility, difficulty focusing, irritability, and forgetfulness
• A frequent need to urinate during the night (nocturia)

When these symptoms are ignored, sleep apnea gradually leaves the body chronically deprived of oxygen. This brings about life-threatening risks such as heart rhythm irregularities, resistant high blood pressure, strokes, and heart attacks. It can also increase insulin resistance, paving the way for the development of Type 2 diabetes.

Diagnosis: How is a Sleep Study (Polysomnography) Performed?

For patients presenting with complaints of snoring and sleep apnea, a definitive diagnosis is made using a sleep study known as polysomnography. Many patients worry about how a sleep study is performed, but the procedure is completely painless and comfortable. It involves the patient staying overnight in a specially designed, quiet sleep room within the hospital.

Before the test begins, small sensors are placed on various parts of the patient's body (head, chest, legs, and fingertips). As the patient falls asleep, these sensors record brain waves, eye movements, heart rate, blood oxygen levels, breathing effort, and leg movements throughout the night. The intensity of snoring, the duration of breathing pauses (apneas), and how many times they occur are also measured in detail. Specialist physicians then analyze this data to determine the severity of the condition (mild, moderate, or severe) and present the most appropriate treatment plan for the patient.

Treatment for Sleep Apnea and Snoring

Treatment for sleep apnea is highly personalized, based on the severity of the condition, the patient's anatomical structure, and underlying causes. The primary goal is to keep the airway open during sleep, prevent drops in blood oxygen, and improve sleep quality. The methods used for snoring treatment generally fall into three main categories:

CPAP Therapy

For moderate to severe cases of sleep apnea, the gold standard treatment is the CPAP (Continuous Positive Airway Pressure) machine. This device delivers a steady, gentle flow of pressurized room air throughout the night via a silicone mask worn over the face or just the nose. This air pressure prevents the tissues in the respiratory tract from collapsing, acting like an invisible splint to keep the airway open. Once patients adjust to the pressure, they typically enjoy deep, uninterrupted sleep, wake up feeling refreshed, and find relief from daytime drowsiness.

Surgical Options

If sleep apnea and snoring are caused by distinct anatomical issues—such as a deviated septum, enlarged adenoids, oversized tonsils, a drooping soft palate, or an elongated uvula—surgical treatment may be recommended. Ear, Nose, and Throat (ENT) specialists can correct the tissues narrowing the airway through radiofrequency treatments, palate surgeries (UPPP), or nasal surgeries. The recovery period usually takes one to two weeks, and by enabling the patient to breathe comfortably and naturally, the snoring problem can often be permanently resolved.

Lifestyle Changes

In mild cases, or to support other treatments, lifestyle modifications are incredibly important. Losing excess weight significantly relieves the airway by reducing fat around the neck. Avoiding alcohol in the evenings, quitting smoking, and choosing to sleep on your side rather than your back can drastically reduce snoring. Maintaining a regular sleep schedule is also part of the treatment. You can find helpful information on this in our article Why It's Important to Maintain Sleep Routines on Holiday. When necessary, custom oral appliances that pull the lower jaw forward to open the airway can also be used under the guidance of a dentist.

Complications and Risk Groups

Sleep apnea is not just a noisy sleep issue; it is a systemic disease that affects the entire body. Every time breathing stops, blood oxygen levels drop to dangerous lows. The heart is forced to beat faster and harder to deliver enough oxygen to the tissues. This overstimulates the sympathetic nervous system, causing blood pressure to spike throughout the night, which over time leads to heart muscle fatigue and hardening of the arteries.

People with severe sleep apnea have a much higher risk of suffering a heart attack or stroke during their sleep compared to healthy individuals. Furthermore, excessive daytime sleepiness sets the stage for fatal workplace and traffic accidents, such as falling asleep at the wheel. Individuals over 40, those with a thick neck circumference (over 43 cm for men, 40 cm for women), those struggling with obesity, people with a receding jawline, and anyone with a family history of sleep apnea fall into the highest risk groups.

When to See a Doctor

Because snoring is so common, it is often dismissed as normal. However, certain accompanying symptoms require urgent medical evaluation. If you experience any of the following, you should see an Ear, Nose, and Throat (ENT) or Pulmonology specialist without delay:

• Your partner or family members tell you that you stop breathing entirely or turn blue in your sleep
• You frequently wake up at night feeling like you're choking, gasping for air, or experiencing heart palpitations
• You wake up in the morning feeling utterly exhausted, as if you've been beaten, despite getting enough hours of sleep
• You involuntarily doze off during the day while sitting, in meetings, reading, or driving
• You experience unexplained severe morning headaches and dry mouth

Because patients with sleep apnea carry a high risk of heart attacks and strokes, if you experience sudden severe chest pain, pain radiating down your left arm, shortness of breath, facial numbness, loss of strength in an arm, or slurred speech, you should call 112 for emergency services immediately.

Frequently Asked Questions

How is a sleep study (polysomnography) performed?

A sleep study is conducted by attaching electrodes and sensors to the patient's body while they sleep overnight in a special room at the hospital. These sensors record heart rate, brain waves, blood oxygen levels, and pauses in breathing. It is a completely painless, needle-free procedure.

How can I stop snoring?

To stop snoring, the underlying cause (such as excess weight, nasal congestion, or a drooping palate) must first be identified. Lifestyle changes like losing weight, sleeping on your side, and quitting alcohol and smoking can be very helpful. If there is an anatomical issue, surgical intervention or the use of a CPAP machine recommended by a doctor may be necessary.

What happens if sleep apnea is left untreated?

Untreated sleep apnea causes the body to repeatedly suffer from oxygen deprivation throughout the night. Over the long term, this significantly increases the risk of high blood pressure, heart rhythm disorders, heart attacks, strokes, and traffic accidents due to excessive daytime sleepiness.

Is snoring surgery risky?

As with any surgical procedure, snoring surgeries carry standard risks related to general anesthesia or bleeding. However, when performed by expert ENT surgeons using modern endoscopic methods and radiofrequency technologies, the success rate is quite high, and the risk of complications is low.

Do I have to use a CPAP machine for the rest of my life?

The duration of CPAP use depends on the patient's condition and the root cause of the disease. For some patients whose apnea is linked to obesity and who lose a significant amount of weight, the use of the machine can be discontinued under a doctor's supervision. However, for patients with ongoing anatomical narrowing or permanent issues, long-term use of the device is vital.
