Overview
Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by interruptions in breathing during sleep. This condition arises when the muscles that support the soft tissues in the throat, such as the tongue and soft palate, relax excessively. This relaxation narrows or completely blocks the airway, leading to temporary cessation of breathing.
Individuals with obstructive sleep apnea often experience repeated episodes of disrupted breathing throughout the night. A common symptom associated with OSA is loud snoring, which occurs when the airway is partially obstructed.
Fortunately, various treatment options exist for obstructive sleep apnea. These include devices that deliver positive pressure to maintain an open airway during sleep, as well as oral appliances that reposition the lower jaw. In some cases, surgical intervention may also be considered.

Symptoms
Common signs of obstructive sleep apnea include:
- Extreme daytime drowsiness
- Loud snoring
- Witnessed episodes of breathing cessation during sleep
- Awakening at night with gasping or choking sensations
- Dry mouth or sore throat upon waking
- Morning headaches
- Difficulty concentrating during the day
- Mood fluctuations, such as irritability or depression
- Elevated blood pressure
- Reduced libido
When to Seek Medical Attention
Consult a healthcare provider if you or your partner notice any of the following:
- Snoring loudly enough to disrupt sleep for yourself or others
- Frequent awakenings gasping for air
- Pauses in breathing during sleep
- Persistent daytime fatigue that may lead to dozing off during activities like driving or watching TV
While loud snoring alone doesn’t necessarily indicate a serious problem, it can be a warning sign of obstructive sleep apnea, especially if accompanied by periods of silence. Discuss any sleep-related issues with your healthcare team, especially if they lead to consistent fatigue and irritability. Excessive daytime sleepiness may also indicate other conditions, such as narcolepsy.

Causes
Obstructive sleep apnea occurs when the muscles at the back of the throat relax excessively, hindering normal breathing. These muscles support the soft palate—the back part of the roof of the mouth—as well as the tongue and the sides of the throat. When these muscles relax, the airway narrows or becomes blocked during inhalation, resulting in reduced oxygen levels in the bloodstream and increased carbon dioxide levels.
The brain detects this interruption in breathing and briefly wakes you to restore airflow, often without you realizing it. You may experience shortness of breath that resolves quickly, accompanied by sounds like snorting or gasping. This pattern can recur multiple times per hour throughout the night, disrupting your ability to enter the deeper stages of restorative sleep, which can leave you feeling fatigued during the day.
Many individuals with obstructive sleep apnea remain unaware of their fragmented sleep patterns, making it crucial to monitor symptoms actively.
Risk Factors
While obstructive sleep apnea can affect anyone, certain factors increase the risk, including:
- Excess Weight: A significant number of individuals with obstructive sleep apnea are overweight, as fatty deposits around the upper airway can obstruct airflow. Medical conditions related to obesity, such as hypothyroidism and polycystic ovary syndrome, can also contribute to OSA.
- Older Age: The likelihood of developing obstructive sleep apnea increases with age, stabilizing after the 60s and 70s.
- Narrowed Airway: Anatomical factors, such as a naturally narrow airway or enlarged tonsils, can predispose individuals to this condition.

To Summarize:
Obstructive sleep apnea is a serious condition that can significantly impact your quality of life. Recognizing the symptoms and understanding the causes can help you seek appropriate treatment. If you suspect you have OSA or experience excessive daytime sleepiness, reaching out to a healthcare professional is essential. There are effective treatments available that can help restore restful sleep and improve overall well-being.
