What is Sleep Apnea

Quick sleep apnea testing is available. We have same-day/next appointments available. Get tested for work today!

Sleep apnea is a prevalent sleep disorder that affects millions of individuals worldwide.

Sleep apnea is characterized by repeated interruptions to your breathing during sleep. These interruptions, known as apneas, can decrease blood oxygen levels and disrupt sleep, impacting overall health and well-being.

Educating yourself about sleep apnea can help you learn more about this condition, determine if you are at risk, and allow you to make more fully informed healthcare decisions. If you have signs, symptoms, or risk factors, completing a sleep study can allow sleep professionals to offer you an accurate diagnosis.

With most cases of sleep apnea undiagnosed, South Chicago Sleep Lab takes pride in educating the Chicago community about sleep apnea and how to get tested.

Over 80% of cases of sleep apnea are undiagnosed

Around 38,000 people in the United States die each year from heart disease, with sleep apnea as a complicating factor

Heart failure risk in people with obstructive sleep apnea is almost 150% higher

Around 20% of adults in the U.S. have at least mild symptoms of sleep apnea

Sleep apnea can lead to serious health consequences.

South Chicago Sleep Lab offers resources to help you learn more about sleep apnea testing, diagnosis, and treatments. We work with local providers that can effectively treat your sleep disorder. 

Types of Sleep Apnea

There are three common types of sleep apnea:

Obstructive Sleep Apnea (OSA)

OSA is the most common type of sleep apnea. This sleep disorder is characterized by repeated interruptions in breathing during sleep. These pauses, known as apneas, can last seconds to minutes and may occur numerous times per hour throughout the night. OSA happens when the throat muscles relax and block the airway.

Central Sleep Apnea (CSA)

CSA is not caused by a blockage of the airway but by the brain failing to send proper signals to the muscles that control breathing. This can result in periods of no breathing or irregular breathing patterns during sleep.


Complex Sleep Apnea Syndrome

Also known as treatment-emergent central sleep apnea, complex sleep apnea syndrome occurs when someone simultaneously has components of both obstructive and central sleep apnea. It can present unique challenges in diagnosis and treatment as it combines elements of both conditions.

The three types of sleep apnea have overlapping symptoms, making it difficult to determine which condition you have without a professional diagnosis.

Whether your diagnosis is OSA, CSA, or complex sleep apnea syndrome, our sleep professionals will facilitate treatments and partner with you to find the right provider.

Risk Factors and Causes

Some factors increase your risk of developing obstructive sleep apnea. While some factors are controllable, such as smoking or drinking habits, others are unavoidable, such as getting older.

Think neck circumference

Age (risk increases as you get older)

Gender (risk increases if you are a man)

Family history


Alcohol and sedative use
Nasal congestion

Other medical conditions*

Sleeping on your back

Each case of sleep apnea is unique, and any risk factors can contribute to or cause sleep. A sleep study can confirm your diagnosis.

*Such as high blood pressure, type 2 diabetes, and chronic lung diseases

Impact of Sleep Apnea

When untreated, sleep disorders can have a devastating impact on health and quality of life.

Sleep apnea can make your day-to-day life more difficult due to poor sleep, daytime fatigue, and noticeable symptoms like snoring.

Sleep apnea can also lead to serious health decisions:

Type 2 diabetes

Heart disease

High blood pressure




Decreased cognitive functions

Sleep apnea is treatable with CPAP and oral device therapy.
