Sleep apnea is a serious sleep-related breathing disorder that affects millions of people and often goes undiagnosed. If left untreated, it can significantly increase the risk of high blood pressure, heart disease, stroke, diabetes, and daytime fatigue that interferes with daily life. At Sleep Houston Sleep and TMJ Therapy, we specialize in identifying and treating sleep-disordered breathing using personalized, non-invasive solutions whenever possible.
Two of the most common forms of sleep apnea are Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA). While both conditions cause repeated pauses in breathing during sleep, they occur for very different reasons. Understanding the distinction is crucial for proper diagnosis and effective treatment.
What Is Sleep Apnea?
Sleep apnea occurs when breathing repeatedly stops and starts during sleep. These interruptions can last from a few seconds to over a minute and may happen dozens or even hundreds of times per night. Each pause reduces oxygen levels and disrupts deep, restorative sleep—often without the person being aware of it.
The two primary types are:
- Obstructive Sleep Apnea (OSA)
- Central Sleep Apnea (CSA)
What Is Obstructive Sleep Apnea (OSA)?
Obstructive Sleep Apnea is the most common form of sleep apnea. It occurs when the muscles of the throat relax excessively during sleep, causing the airway to collapse or become blocked.
Common Causes of OSA
- Relaxation of throat muscles during sleep
- Narrow airway anatomy
- Enlarged tonsils or tongue
- Obesity or excess neck tissue
- TMJ disorders or jaw positioning issues
Common Symptoms of OSA
- Loud, chronic snoring
- Gasping or choking during sleep
- Excessive daytime sleepiness
- Morning headaches
- Dry mouth or sore throat upon waking
- Difficulty concentrating
OSA is often associated with snoring, but not everyone who snores has sleep apnea. A proper sleep evaluation is essential for diagnosis.
What Is Central Sleep Apnea (CSA)?
Central Sleep Apnea is less common and occurs when the brain fails to send consistent signals to the muscles responsible for breathing. Unlike OSA, there is no physical blockage of the airway.
Common Causes of CSA
- Neurological conditions (such as stroke or brain injury)
- Heart failure
- Certain medications (especially opioids)
- Disorders affecting the brainstem
Common Symptoms of CSA
- Repeated pauses in breathing without snoring
- Shortness of breath upon awakening
- Insomnia or difficulty staying asleep
- Daytime fatigue
- Poor sleep quality
Because CSA is related to brain signaling rather than airway obstruction, its treatment approach is often different from OSA.
Key Differences Between Obstructive and Central Sleep Apnea
| Feature | Obstructive Sleep Apnea | Central Sleep Apnea |
| Cause | Physical airway blockage | Brain signaling issue |
| Snoring | Very common | Rare |
| Breathing effort | Present but blocked | Absent during pauses |
| Most common type | Yes | No |
| Oral appliance therapy | Often effective | Usually not primary |
How Are These Conditions Diagnosed?
Both OSA and CSA are diagnosed through a sleep study, either in-lab or at home, depending on the patient’s needs. These studies measure breathing patterns, oxygen levels, heart rate, and brain activity during sleep.
At Sleep Houston Sleep and TMJ Therapy, we work closely with sleep physicians and utilize advanced diagnostic tools to ensure accurate identification of the type and severity of sleep apnea.
Treatment Options at Sleep Houston Sleep and TMJ Therapy
Obstructive Sleep Apnea Treatment
For many patients with OSA, especially those with mild to moderate cases, custom oral appliance therapy is an effective and comfortable alternative to CPAP. These devices gently reposition the jaw and tongue to keep the airway open during sleep.
Benefits include:
- Comfortable and non-invasive
- Quiet and travel-friendly
- Custom-designed for your bite and jaw
- Can also help patients with TMJ concerns
Central Sleep Apnea Treatment
CSA treatment often focuses on managing the underlying medical condition and may involve:
- Medical coordination with physicians
- Advanced positive airway pressure therapies
- Medication adjustments
Our team helps guide patients toward the appropriate care pathway.
Comprehensive Q&A: Obstructive vs. Central Sleep Apnea
Q: Can someone have both obstructive and central sleep apnea?
A: Yes. This condition is known as complex sleep apnea and requires specialized evaluation and treatment.
Q: Is snoring always a sign of sleep apnea?
A: No, but loud, chronic snoring—especially when paired with daytime fatigue—should be evaluated.
Q: Can TMJ issues contribute to sleep apnea?
A: Yes. Jaw alignment and airway anatomy play a significant role in obstructive sleep apnea. Treating TMJ disorders can improve airway stability.
Q: Is CPAP the only treatment for sleep apnea?
A: No. Oral appliance therapy is a highly effective alternative for many patients with obstructive sleep apnea.
Q: How long does it take to notice improvement with treatment?
A: Many patients notice improved sleep quality, energy, and focus within days to weeks of consistent treatment.
Q: What happens if sleep apnea is left untreated?
A: Untreated sleep apnea increases the risk of heart disease, stroke, diabetes, depression, and accidents due to fatigue.
