Sleep Apnea Demystified: Types, Symptoms, Diagnosis, and Treatment Options

morningdovemarketing • Oct 10, 2023

Sleep apnea, a common yet often underdiagnosed sleep disorder, affects millions of individuals across the globe. It is characterized by recurrent episodes of partial or complete airway blockage during sleep, leading to disrupted sleep, snoring, gasping for air, and interrupted breathing.


The consequences of untreated sleep apnea may extend well beyond disrupted sleep, impacting overall health and increasing the risk of serious medical conditions, such as hypertension, heart disease, and stroke.


At Chattanooga Sleep Center, our team of dedicated medical professionals excels in providing comprehensive diagnostic and treatment services for sleep apnea in Chattanooga, TN, ensuring that those affected receive the crucial care and support they need for improved sleep health and well-being.


In this informative and insightful blog article, we will delve into the intricacies of sleep apnea, discussing its various types – obstructive sleep apnea (OSA), central sleep apnea (CSA), and complex sleep apnea syndrome (CompSAS) – their distinguishing symptoms, and potential risk factors. Additionally, we will detail the diagnosis and evaluation process for sleep apnea, including the role of sleep studies and the contribution of specialized equipment such as continuous positive airway pressure (CPAP) machines, oral appliances, or other treatment modalities.

Types of Sleep Apnea: Obstructive, Central, and Complex Sleep Apnea

Sleep apnea can be classified into three distinct forms, each with its unique characteristics and causes:


  1. Obstructive Sleep Apnea (OSA): The most common type, OSA is caused by the partial or complete collapse of the upper airway during sleep, leading to disrupted breathing. Risk factors for OSA include obesity, a family history of sleep apnea, large neck circumference, and certain anatomical features such as a narrowed airway or enlarged tongue.
  2. Central Sleep Apnea (CSA): Unlike OSA, CSA results from the brain's failure to transmit the proper signals to the muscles responsible for breathing control during sleep. Causes of CSA may include heart disease, stroke, or brainstem disorders, and the use of certain medications, such as opioids.
  3. Complex Sleep Apnea Syndrome (CompSAS): Also known as treatment-emergent central sleep apnea, CompSAS occurs when an individual exhibits both OSA and CSA characteristics. This form of sleep apnea often arises during the initial treatment of OSA with Continuous Positive Airway Pressure (CPAP) therapy.

Recognizing Sleep Apnea Symptoms and Risk Factors

Identifying the signs and symptoms of sleep apnea is vital in addressing the condition early and seeking appropriate care:


  1. Common Symptoms: Frequent loud snoring, gasping for air during sleep, episodes of breathing cessation observed by others, difficulty staying asleep, excessive daytime sleepiness, attention problems, and irritability are notable indicators of potential sleep apnea.
  2. Risk Factors: Several factors may increase the likelihood of developing sleep apnea, such as obesity, advanced age, male gender, family history, alcohol or sedative use, smoking, nasal congestion, and underlying medical conditions, such as type 2 diabetes or heart diseases.

Diagnosis and Evaluation for Sleep Apnea: The Role of Sleep Studies and Medical Examinations

Accurate diagnosis is essential for the proper treatment of sleep apnea:


  1. Medical and Sleep History Evaluation: A comprehensive assessment of sleep patterns, snoring, choking instances, and other symptoms will be conducted during a detailed sleep history evaluation.
  2. Physical Examination: A thorough physical examination will follow, including the evaluation of the airway structure, neck circumference, and body mass index (BMI) to identify potential anatomical or physiological factors contributing to sleep apnea.
  3. Sleep Studies: Polysomnography (PSG) and home sleep tests are commonly employed to assess and diagnose sleep apnea. These evaluations record essential data during sleep, such as respiratory patterns, oxygen levels, and heart rates, which are reviewed by a sleep specialist to determine appropriate diagnoses and recommendations.

Treatment Options for Sleep Apnea: CPAP, Oral Appliances, and Lifestyle Changes

Several effective treatment options are available for sleep apnea management:


  1. Continuous Positive Airway Pressure (CPAP) Therapy: The gold standard for treating moderate to severe OSA, CPAP therapy involves the use of a machine that delivers a continuous flow of air through a mask to maintain an open airway during sleep.
  2. Oral Appliances: Custom-fitted dental devices, such as mandibular advancement devices (MADs) or tongue-retaining devices, can be used to reposition the jaw or tongue, ensuring an open airway during sleep. These devices can effectively manage mild to moderate OSA and may be preferred for those who cannot tolerate CPAP therapy.
  3. Lifestyle Changes: Addressing underlying risk factors, such as obesity or smoking, can play a crucial role in alleviating sleep apnea. Weight loss, regular exercise, sleep hygiene improvements, and positional therapy (e.g., sleeping on one's side instead of the back) can all contribute to better sleep quality.
  4. Additional Treatment Options: In some cases, surgical intervention, such as uvulopalatopharyngoplasty (UPPP) or genioglossus advancement (GA), may be recommended to correct anatomical issues contributing to sleep apnea. For CSA, adaptive servo-ventilation (ASV) or certain medications may be prescribed, depending on the nature and severity of the condition.

The Importance of Seeking Professional Guidance and Support

Sleep specialists play a crucial role in the comprehensive management of sleep apnea:


  1. Expert Assessment and Diagnosis: Sleep specialists have the knowledge and expertise to accurately diagnose sleep apnea, considering all potential contributing factors and underlying conditions.
  2. Personalized Treatment Plans: Working closely with patients, sleep specialists develop tailored treatment plans that incorporate the appropriate combination of therapies best suited to each individual's specific needs.
  3. Ongoing Support and Monitoring: As treatment progresses, sleep specialists provide continuous support, closely monitoring response to treatment and making necessary adjustments to optimize outcomes and sleep health improvements.
