Sleep Apnea: Causes, Symptoms & Treatment

Sleep apnea is a common sleep disorder characterized by repeated episodes of breathing cessation or reduced airflow during sleep. This condition is estimated to affect more than 20 million adults in the United States alone and can have significant impacts on a person’s quality of life and overall health. In this article, we will explore the causes, symptoms, diagnosis, and treatment options for sleep apnea.

Causes of Sleep Apnea

Sleep apnea occurs when the muscles in the back of the throat fail to keep the airway open during sleep. This can be caused by a variety of factors, including:

  1. Obesity: People who are overweight or obese have excess tissue in the throat, which can narrow the airway and make breathing more difficult.
  2. Aging: As we age, our muscles and tissues become weaker, including the muscles that keep the airway open during sleep.
  3. Genetics: Some people are genetically predisposed to sleep apnea, and the condition can run in families.
  4. Alcohol and sedatives: Alcohol and sedatives can relax the muscles in the throat, making breathing more difficult during sleep.
  5. Smoking: Smoking can cause inflammation and swelling in the airways, which can narrow the airway and make breathing more difficult.

Symptoms of Sleep Apnea

The most common sleep apnea symptoms is loud and persistent snoring, but there are other signs and symptoms to watch for, including:

  1. Excessive daytime sleepiness: People with sleep apnea often feel tired and fatigued during the day, even after a full night’s sleep.
  2. Gasping or choking during sleep: This is a sign that breathing has temporarily stopped, and the person is struggling to catch their breath.
  3. Morning headaches: Sleep apnea can cause oxygen levels to drop during the night, leading to headaches in the morning.
  4. Difficulty concentrating: People with sleep apnea often have trouble focusing and may experience memory problems.
  5. Mood changes: Sleep apnea can cause irritability, depression, and anxiety.


If you suspect that you or a loved one has sleep apnea, it’s important to talk to a healthcare provider. A diagnosis of sleep apnea typically involves a sleep study, which can be done in a sleep center or at home. During a sleep study, a variety of measurements are taken, including:

  1. Oxygen levels: Oxygen levels are monitored throughout the night to determine if they drop during periods of breathing cessation.
  2. Heart rate: Heart rate is monitored throughout the night to detect any abnormalities.
  3. Brain waves: Brain waves are monitored to determine the quality of sleep and if the person is waking up frequently during the night.
  4. Snoring: Snoring is recorded to determine if it is loud and persistent, which is a common sign of sleep apnea.

Sleep Apnea Treatment

The treatment for sleep apnea depends on the severity of the condition and the underlying causes. In some cases, lifestyle changes may be enough to improve symptoms, while in other cases, more aggressive treatments may be necessary. Some treatment options for sleep apnea include:

  1. Lifestyle changes: Losing weight, quitting smoking, and avoiding alcohol and sedatives before bed can all help improve symptoms of sleep apnea.
  2. Continuous Positive Airway Pressure (CPAP): CPAP is a machine that delivers a constant flow of air through a mask worn over the nose and/or mouth during sleep. This helps keep the airway open and prevents breathing cessation.
  3. Oral appliances: Oral appliances are custom-made devices that are worn in the mouth during sleep. These devices help keep the airway open by repositioning the jaw and tongue.
  4. Surgery: In severe cases of sleep apnea, surgery may be necessary to remove excess tissue from the throat or reposition the jaw to open the airway.
  1. Positional therapy: Sleeping in a certain position can sometimes worsen sleep apnea symptoms. Positional therapy involves using special devices or pillows to encourage sleeping in a position that keeps the airway open.
  2. Medications: Certain medications, such as nasal steroids or anti-anxiety medications, may be used to reduce inflammation or anxiety-related breathing difficulties that can contribute to sleep apnea.
  3. Lifestyle modifications: Simple lifestyle modifications can also help alleviate sleep apnea symptoms, such as avoiding alcohol before bed, quitting smoking, and establishing a regular sleep schedule.

It’s important to note that treatment for sleep apnea should always be supervised by a healthcare provider. A healthcare provider can help determine the best course of treatment based on the severity of the condition and individual factors such as age, weight, and overall health.

Complications of Sleep Apnea

Untreated sleep apnea can lead to a variety of health complications, including:

  1. High blood pressure: Sleep apnea can cause blood pressure to rise during the night, which can lead to long-term hypertension.
  2. Cardiovascular disease: People with sleep apnea are at increased risk of developing heart disease and other cardiovascular conditions.
  3. Type 2 diabetes: Sleep apnea has been linked to an increased risk of developing type 2 diabetes.
  4. Depression and anxiety: Sleep apnea can contribute to symptoms of depression and anxiety.
  5. Impaired cognitive function: Sleep apnea can lead to impaired cognitive function, including memory problems and difficulty concentrating.


Sleep apnea is a common sleep disorder that can have significant impacts on a person’s health and quality of life. Symptoms of sleep apnea include loud and persistent snoring, gasping or choking during sleep, and excessive daytime sleepiness. If you suspect that you or a loved one has sleep apnea, it’s important to talk to a healthcare provider and get a proper diagnosis. Treatment for sleep apnea depends on the severity of the condition and underlying causes but can include lifestyle changes, CPAP machines, oral appliances, surgery, and positional therapy. With proper treatment, people with sleep apnea can experience significant improvements in their symptoms and overall health.
