Why Sleep Apnea Happens: Understanding the Causes

Common symptoms include gasping for air during sleep, chronic fatigue, and even morning headaches. At Houston Sleep Solutions, we understand the importance of uncovering the causes of sleep apnea to provide effective treatment and help you regain restorative sleep.

What Is Sleep Apnea?

Sleep apnea occurs when your breathing repeatedly stops and starts during sleep. There are three main types:

  • Obstructive Sleep Apnea (OSA): The most common type, caused by a physical blockage of the airway.
  • Central Sleep Apnea (CSA): Results from the brain failing to signal the muscles to breathe adequately.
  • Complex Sleep Apnea Syndrome (also called treatment-emergent CSA): A combination of OSA and CSA.

When untreated, sleep apnea can lead to serious health issues, including high blood pressure, heart disease, and an increased risk of accidents due to daytime fatigue.

Common Causes of Obstructive Sleep Apnea (OSA)

Anatomy & Airway Blockages

Certain anatomical features can make it harder to maintain an open airway during sleep. Enlarged tonsils, a thick neck, or a naturally narrow airway can all contribute to blockages that lead to OSA.

Obesity & Excess Weight

Excess weight is a significant risk factor for sleep apnea. Fat deposits around the neck and throat can narrow the airway, making it harder to breathe, especially when lying down.

Muscle Relaxation During Sleep

When you’re asleep, the muscles in your throat naturally relax. For individuals with OSA, these relaxed muscles can collapse, blocking the airflow and causing breathing interruptions.

Other Risk Factors for Sleep Apnea

Genetics

A family history of sleep apnea or inherited traits like a recessed jaw can increase your risk.

Age & Gender

Men are more likely than women to experience sleep apnea, particularly middle-aged and older adults, though the risk rises for post-menopausal women.

Lifestyle Factors

Smoking, excessive alcohol consumption, and sedatives can worsen sleep apnea by further relaxing the airway muscles or increasing inflammation.

Causes of Central Sleep Apnea (CSA)

Brain Signal Issues

With CSA, the brain fails to send the correct signals to the muscles that control breathing, interrupting the cycle.

Medical Conditions

CSA is often linked to underlying health conditions such as stroke, heart failure, or neurological illnesses like Parkinson’s disease.

Certain Medications

Opioids and other medications that suppress the central nervous system can disrupt the brain’s ability to regulate breathing during sleep.
