Snoring and Sleep Apnea

What Are Snoring and Sleep Apnea?

Snoring is a sound produced during sleep when soft tissues in the upper airway vibrate with air flow. When sleep begins, the soft palate, uvula, tonsils, and muscles around the tongue base relax, narrowing the airway. Air passing through the narrowed area speeds up and vibrates the tissues, producing the snoring sound.

In simple snoring, sound is present but breathing largely continues and blood oxygen level does not drop significantly. In obstructive sleep apnea syndrome (OSAS), the airway becomes repeatedly blocked during sleep. Breathing stops or becomes shallow for durations of ten seconds or more, blood oxygen drops, and the brain briefly arouses the person to restart breathing. This cycle can occur many times throughout the night and prevents reaching the restful deep sleep stages.

For this reason, snoring is not a diagnosis in itself but a symptom. Not everyone who snores has sleep apnea; however, most people with sleep apnea do snore. Their distinction can only be made with appropriate evaluation.

Symptoms and When to See a Doctor

Sleep apnea symptoms fall into two groups: nighttime and daytime. The nighttime symptoms are often noticed not by the person themselves but by a bed partner or family members. Daytime symptoms develop gradually and are frequently attributed to busy schedules or age.

• Loud, irregular snoring with silent pauses in between
• Witnessed apnea, meaning someone else observing breathing stop during sleep
• Sensation of gasping, choking, or coughing while waking
• Frequent nighttime urination, sweating, and restless, fragmented sleep
• Morning mouth and throat dryness, dull headache, feeling unrefreshed upon waking
• Difficulty staying awake during the day; dozing off while reading, watching television, or driving
• Concentration difficulty, forgetfulness, irritability, and lack of motivation

Relationship to Overall Health

Repeated oxygen drops and micro-arousals in sleep apnea keep the nervous system and circulation aroused throughout the night. When untreated, medical literature extensively demonstrates increased risk of high blood pressure, heart rhythm disorders, heart failure, stroke, and adversely affected blood sugar regulation. For this reason, sleep apnea is addressed not merely as a sleep problem but as a condition affecting overall health.

Daytime sleepiness from fragmented sleep increases the likelihood of workplace and traffic accidents. Additionally, mood fluctuations and attention and memory problems may occur. The degree of impact in any individual varies with disease severity, how long it has been present, and accompanying conditions; evaluation is therefore individualized.

Especially the combination of witnessed apnea history, inability to feel rested upon waking, and daytime sleepiness is a presentation requiring evaluation. Some of these symptoms may result from causes other than sleep apnea; differentiation is made through examination and necessary testing.

Diagnosis: Sleep Testing and Endoscopic Evaluation

Evaluation begins with detailed history. Sleep pattern, degree of daytime sleepiness, weight changes, tobacco and alcohol use, medications used, and accompanying conditions are inquired. Then examination of nose, nasopharynx, mouth, and throat is performed; nasal obstruction, septum deviation, turbinate size, tonsil and adenoid size, soft palate structure, and tongue base are evaluated.

The method used to clarify diagnosis is sleep testing. In this test called polysomnography, breathing effort, air flow, blood oxygen level, heart rhythm, brain waves, and body movements are recorded during sleep. The apnea-hypopnea index obtained reveals disease severity and forms the basis of treatment planning. In some appropriate situations, more limited home recording systems may be used.

To visualize at what level airway narrowing occurs, flexible endoscopy examines the nose and throat. In selected individuals, endoscopic evaluation during drug-induced sleep-like state (DISE) may be performed. This directly shows which levels—palate, tonsil, tongue base, and laryngeal entrance—contribute to narrowing. This examination is particularly helpful in planning when surgical options are discussed with the patient.

Treatment Options

Treatment is planned based on disease severity, level of airway obstruction, patient age, weight, accompanying conditions, and preferences. Two people with the same diagnosis do not necessarily need the same approach.

• Lifestyle modifications: weight loss, avoiding alcohol and sedative medications in evening hours, smoking cessation, establishing proper sleep schedule, and for position-dependent cases, supporting side sleeping
• Positive airway pressure (CPAP) therapy: pressurized air delivered through a mask during sleep keeps the airway open. It is widely used in moderate and severe sleep apnea; benefit depends on regular device use
• Oral appliances: devices prepared with dentist collaboration that advance the lower jaw and tongue to widen the airway. May be an option in mild to moderate cases or for those unable to use CPAP
• Nose-level surgeries: straightening of septal deviation (septoplasty) and turbinate reduction procedures. May improve nasal breathing and contribute to sleep quality and CPAP compliance
• Palate and tonsil level surgeries: removal of tonsils combined with reshaping of soft palate and pharyngeal sidewalls using pharyngoplasty techniques
• Tongue base level interventions: procedures aimed at reducing tongue base volume or advancing the tongue; generally determined by endoscopic findings

Surgical Process and Recovery

The scope of sleep surgery varies with the procedure performed. Operations targeting only nasal structures typically involve brief hospitalization. After procedures at the palate, tonsil, and tongue base level, however, discomfort and throat pain may last one to two weeks. During this time, eating soft and lukewarm foods, ample fluid intake, and regular use of medications recommended by the physician are advised.

All surgical procedures carry risks such as bleeding, infection, anesthesia-related problems, and slower-than-expected healing progress. These are explained in detail during the pre-operative discussion, and informed consent is part of this conversation. After sleep apnea surgery, breathing may need to be re-measured with follow-up sleep testing after a certain time has passed.

Results vary from person to person. Weight gain, tissue relaxation with age, and allergic symptoms may affect the picture over time. Therefore, post-treatment follow-up is planned as an integral part of the process.

Important Considerations

Sleep apnea requires multifaceted evaluation for both diagnosis and treatment. The information on this page is for general education and does not replace examination; diagnosis and treatment decisions are made after patient history, examination findings, and test results are evaluated together. Outcomes of applied methods vary from person to person. For appointments and information, contact can be made.

Points that may be remembered throughout the process are as follows.

• Snoring complaint alone does not establish sleep apnea diagnosis; distinction is made by sleep testing and snoring loudness does not indicate disease severity
• Persons reporting significant daytime sleepiness should discuss vehicle and hazardous machinery use with their physician
• Weight management is a supporting component of treatment; however, sleep apnea can occur in people of any weight
• In CPAP therapy, mask fit and regular device use are determinants of benefit obtained. When compliance difficulty occurs, adjustments and mask changes may be evaluated
• Over-the-counter nasal strips, sprays, and similar products may provide relief sensation in some people; however, they do not replace sleep apnea treatment
• When any surgery and anesthesia is planned in people with sleep apnea, informing the relevant physicians of this condition is important
