Sleep Apnea Syndromes (Obstructive, Central, Mixed):

What Is Sleep Apnea?

Sleep apnea is a conceivably genuine sleep issue in which breathing consistently stops and starts. In the event that you wheeze boisterously and feel tired even following an entire night's sleep, you may have sleep apnea.

The primary sorts of sleep apnea are:

  • Obstructive Sleep Apnea

The more normal structure that happens when throat muscles unwind.

  • Central Sleep Apnea
  • Complex Sleep Apnea Condition

 Also, otherwise called treatment-emanant central sleep apnea, which happens when somebody has both obstructive sleep apnea and central sleep apnea

On the off chance that you figure you may have sleep apnea, see your primary care physician. Treatment can facilitate your indications and might help forestall heart issues and different confusions.

Manifestations Of Sleep Apnea

The signs and manifestations of obstructive and central sleep apneas cover, now and again making it hard to figure out which type you have. The most widely recognized signs and indications of obstructive and central sleep apneas include:

  • Noisy snoring
  • Gasping for breath during sleep
  • Awakening with a dry mouth
  • Morning cerebral pain
  • Trouble staying unconscious (a sleeping disorder)
  • Inordinate daytime sleepiness (hypersomnia)
  • Trouble focusing while conscious
  • Peevishness

When To See A Specialist

Boisterous snoring can demonstrate a conceivably significant issue, however not every person who has sleep apnea wheezes. Converse with your primary care physician in the event that you have signs or manifestations of sleep apnea. Get some information about any sleep issue that leaves you exhausted, sleepy and irritated.

Sleep Apnea Syndromes (Obstructive, Central, Mixed): 

Sleep apnea is a condition that causes you to stop breathing while you’re sleeping. The word “apnea” comes from the Greek word for “breathless.” Sleep apnea happens because you stop breathing in your sleep. 


Sleep apnea usually has specific causes, and there’s evidence that it may run in families. Overall, there are three main forms of sleep apnea, with some differences in how and why they happen.


There are three types:

  1. Obstructive sleep apnea: This is the most common type. It happens when your airways repeatedly become completely or partially blocked during sleep, usually because the soft tissue in the back of your throat collapses. During these episodes, your diaphragm and chest muscles work harder than normal to open your airways. You may start to breathe with loud gasps or jerk your body. This can affect your sleep, lower the flow of oxygen to your vital organs, and lead to abnormal heart rhythms.
  2. Central sleep apnea: With this type, your airway doesn’t become blocked. Instead, your brain fails to tell your muscles to breathe because of issues in your respiratory control center. It’s related to the function of your central nervous system. Central sleep apnea happens most often in people with neuromuscular disease such as amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease), those who’ve had a stroke, or in people with heart failure or other forms of heart, kidney, or lung disease.
  3. Complex sleep apnea syndrome: This condition, which doctors also call treatment-emergent central sleep apnea, happens when you have both obstructive sleep apnea and central sleep apnea.


The symptoms of obstructive and central sleep apneas overlap, sometimes making it difficult to determine which type you have. The most common symptoms of obstructive and central sleep apneas include:

  • Loud snoring
  • Episodes in which you stop breathing during sleep — which would be reported by another person
  • Gasping for air during sleep
  • Awakening with a dry mouth
  • Morning headache
  • Difficulty staying asleep, known as insomnia
  • Excessive daytime sleepiness, known as hypersomnia
  • Difficulty paying attention while awake
  • Irritability


Your healthcare provider may make an evaluation based on your symptoms and sleep history, which you can provide with help from someone who shares your bed or your household, if possible. You're likely to be referred to a sleep disorder center. There, a sleep specialist can help you determine your need for further evaluation.

An evaluation often involves overnight monitoring of your breathing and other body functions during sleep testing at a sleep center. Home sleep testing also might be an option. Tests to detect sleep apnea include:

  1. Nocturnal polysomnography
  2. Home sleep tests

If you have obstructive sleep apnea, your healthcare provider might refer you to an ear, nose, and throat specialist to rule out a blockage in your nose or throat. An evaluation by a heart specialist, known as a cardiologist, or a doctor who specializes in the nervous system, called a neurologist, might be necessary to look for causes of central sleep apnea.
