Causes of Sleep Apnea

Three types of Sleep Apnea are there that can cause blocking or collapse of the airways. These include:

Obstructive sleep apnea - Healthians

Obstructive Sleep Apnea (OSA)

OSA is the most common types of Sleep Apnea, and it occurs when the air is not able to reach the lungs because of collapse in the upper airways. It is because of the over-relaxation of the throat muscles, which then affects the normal breathing.

Reason: When the muscles are in a relaxed phase, the airways narrow or close as a person breathes in and this can cause inadequate breathing for about 10 to 20 sec. It might lead to a buildup of carbon monoxide, by lowering the oxygen levels. People suffering from OSA may not be aware of their interrupted sleep, and they feel that they slept well.

OSA occurs in three phases

Phase 1: Airway is partly blocked, leading to loud snoring

Phase 2: Airway collapses and the airflow through it stops entirely, or significantly diminishes for at least 10 seconds and can go up to 2 minutes.

Phase 3: In this phase, the individual mostly wakes up and often snorts or gasps for air. Once the breath is gasped, the person returns to his sleep, and the cycles get repeated.

Common Causes

In adults these are:

  • Excessive weight
  • Obesity
  • Hypertension
  • Diabetes
  • Men are more likely to be impacted by OSA
  • Smokers
  • Diabetes
  • Heredity
  • Asthma

In children:

  • Enlarged tonsils
  • Certain dental conditions like overbite
  • Some less common conditions are there like, tumor or growth in the airways, congenital disabilities, childhood obesity

Central sleep apnea - Healthians

Central Sleep Apnea

It is a rare condition. In this, the breathing gets disrupted during the sleep cycle due to a problem in the brain or heart.

Reason: In central sleep apnea the brainisunable to send proper signals to the muscles that have been controlling the breathing cycle. In this condition, the person will not try to breathe as the brain is not giving the desired signals.


It is common in adults and is mostly associated with severe illness, that includes

    • Congestive heart failure
    • Hypothyroid disease
    • Kidney failure
    • A specific neurological disease like Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis
    • Any damage to the brain stem, like in cases of encephalitis, stroke, injury or other factors
    • Due to a drug or substance use

Mixed Sleep apnea - Healthians

Mixed Sleep Apnea

Mixed sleep apnea includes both central sleep apnea and obstructive sleep apnea, starting from central sleep apnea.


Sleep apnea is diagnosed based on the signs and symptoms and sleep history provided by the patient. Some of the standard test advised for the diagnosis includes:

  • Nocturnal polysomnography
  • Home sleep test


Treatment of sleep apnea will depend on its type and stage.

In mild cases:

    •  Lifestyle changes can help like weight loss or cigarette cessation.
    • When it is due to nasal allergy, then taking anti-allergic on the recommendation of the doctors can help.

In severe cases:

If these measures are not able to provide any relief, then other treatment options are available:

  • Certain devices can assist in opening blocked airways
  • Surgery, in certain cases
  • Therapies: Certain therapies can help, these are
    • Continuous positive airway pressure
    • Another airway pressure device
    • Oral appliances

Your doctor will be able to guide regarding the most suitable option for you!

Risk Factors

Risk factors that are common for sleep apnea include:

  • Obesity
  • Chronic sinusitis
  • Large neck circumference
  • Any recent weight gains
  • Sleeping in the supine position
  • Large tonsils or adenoids
  • Smoking
  • Suffering from Down syndrome
  • Family history
