Obstructive Sleep Apnea (OSA): Symptoms, Causes, Treatment
What are the symptoms of obstructive sleep apnea?
Obstructive sleep apnea (OSA) is a sleep disorder characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to breathing pauses and disrupted sleep patterns. Symptoms of obstructive sleep apnea can vary in severity but often include:
- Loud Snoring: Persistent, loud snoring is a common symptom of obstructive sleep apnea. The snoring may be interrupted by periods of silence followed by gasping or choking sounds as breathing resumes.
- Episodes of Breathing Pauses: Witnessed episodes where breathing stops or becomes shallow during sleep. These pauses can last for a few seconds to minutes and may be accompanied by choking or gasping sounds as breathing resumes.
- Excessive Daytime Sleepiness: People with obstructive sleep apnea often experience excessive daytime sleepiness, which can lead to difficulty staying awake or alert during the day. This can interfere with daily activities and increase the risk of accidents.
- Morning Headaches: Waking up with a headache, especially in the morning, is a common symptom of obstructive sleep apnea. This is thought to be due to changes in oxygen levels and carbon dioxide levels during sleep.
- Fatigue and Irritability: Chronic fatigue and irritability are common symptoms of obstructive sleep apnea, as disrupted sleep patterns can lead to poor quality sleep.
- Difficulty Concentrating: Difficulty concentrating, memory problems, and poor decision-making are common cognitive symptoms of obstructive sleep apnea due to the effects of sleep disruption on brain function.
- Mood Changes: Mood swings, depression, and anxiety can occur in people with obstructive sleep apnea, likely due to the impact of disrupted sleep on emotional regulation.
- Dry Mouth or Sore Throat: Waking up with a dry mouth or sore throat can be a sign of breathing through the mouth during sleep, which is common in obstructive sleep apnea.
- Restless Sleep: Restless sleep, frequent awakenings, or tossing and turning during sleep can be indicators of obstructive sleep apnea.
It’s important to note that not everyone with obstructive sleep apnea will experience all of these symptoms, and symptoms can vary depending on the individual. If you or someone you know is experiencing symptoms of obstructive sleep apnea, it’s important to seek evaluation and treatment from a healthcare provider, as untreated sleep apnea can lead to serious health complications.
What are the causes of obstructive sleep apnea?
Obstructive sleep apnea (OSA) occurs when the muscles in the back of your throat relax too much to allow normal breathing. These muscles support the soft palate, uvula, tonsils, and tongue. When the muscles relax, your airway narrows or closes as you breathe in, and you can’t get an adequate breath in. This may lower the level of oxygen in your blood. Your brain senses this inability to breathe and briefly rouses you from sleep so that you can reopen your airway. This awakening is usually so brief that you don’t remember it.
Factors that may increase your risk of obstructive sleep apnea include:
- Excess weight. Obesity greatly increases the risk of sleep apnea. Fat deposits around your upper airway can obstruct your breathing.
- Neck circumference. People with thicker necks might have narrower airways.
- A narrowed airway. You might inherit a naturally narrow throat. Or, your tonsils or adenoids might become enlarged, which can block your airway.
- Being male. Men are more likely to have obstructive sleep apnea than are women. However, women increase their risk if they’re overweight, and their risk also appears to rise after menopause.
- Being older. Sleep apnea occurs significantly more often in older adults.
- Family history. If you have family members with sleep apnea, you might be at increased risk.
- Use of alcohol, sedatives, or tranquilizers. These substances relax the muscles in your throat, which can worsen obstructive sleep apnea.
- Smoking. Smokers are three times more likely to have obstructive sleep apnea than are people who’ve never smoked. Smoking can increase the amount of inflammation and fluid retention in the upper airway, so you might want to think about quitting.
What is the treatment for obstructive sleep apnea?
The treatment for obstructive sleep apnea (OSA) depends on the severity of the condition and its underlying causes. Treatment options may include:
- Lifestyle Changes:
- Weight loss: Losing weight can help reduce the severity of OSA, especially in cases where obesity is a contributing factor.
- Avoiding alcohol and sedatives: These substances can relax the muscles in the throat, making it more likely for the airway to become obstructed during sleep.
- Changing sleep position: Sleeping on your side instead of your back can help prevent the tongue and soft palate from collapsing into the airway.
- Continuous Positive Airway Pressure (CPAP):
- CPAP is the most common and effective treatment for moderate to severe OSA.
- A CPAP machine delivers a steady stream of air through a mask worn over the nose or nose and mouth during sleep, keeping the airway open and preventing pauses in breathing.
- Oral Appliances:
- Oral appliances are devices that are worn in the mouth during sleep to help keep the airway open.
- They are usually recommended for mild to moderate OSA or for people who cannot tolerate CPAP.
- Surgery:
- Surgery may be an option for people with severe OSA who have not responded to other treatments.
- Surgical procedures may include removing excess tissue in the throat, repositioning the jaw to enlarge the airway, or inserting implants to stiffen the soft palate.
- Other Treatments:
- Nasal decongestants or allergy medications: These may help improve nasal congestion and airflow.
- Inspire therapy: This is a newer treatment option that involves surgically implanting a device that stimulates the nerve that controls the tongue movement, helping to keep the airway open during sleep.
Treatment for OSA should be individualized based on the specific needs and preferences of the patient. It’s important to work with a healthcare provider experienced in sleep disorders to determine the most appropriate treatment approach. Left untreated, OSA can lead to serious health complications, so seeking treatment is important.
