Sleep apnea is a common sleep disorder characterized by interruptions in breathing during sleep. These breathing disruptions can occur dozens of times throughout the night, leading to poor sleep quality and other negative health consequences. There are several causes of sleep apnea, including anatomical factors, medical conditions, and lifestyle habits.
Anatomical factors
The most common cause of sleep apnea is anatomical factors. This includes the shape and size of the airway, which can lead to a narrowing of the airway and subsequent breathing difficulties. The following anatomical factors are associated with sleep apnea:
Obesity: People who are overweight or obese are at a higher risk of developing sleep apnea. The extra weight around the neck can put pressure on the airway, causing it to narrow or collapse.
Enlarged tonsils and adenoids: Children with enlarged tonsils and adenoids are at an increased risk of developing sleep apnea. These tissues can obstruct the airway and cause breathing difficulties during sleep.
Deviated septum: A deviated septum is a condition where the nasal septum, the cartilage that divides the nose into two nostrils, is crooked or misaligned. This can make it difficult to breathe through the nose, leading to snoring and sleep apnea.
Small jaw: A small jaw can lead to a smaller airway, making it more likely to collapse during sleep.
Large tongue: A large tongue can obstruct the airway and cause breathing difficulties during sleep.
Medical conditions
There are several medical conditions that can cause or contribute to sleep apnea. These conditions can affect the muscles and tissues in the airway, making them more likely to collapse during sleep. Some of the medical conditions associated with sleep apnea include:
Hypothyroidism: Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone. This can cause the muscles in the airway to weaken, leading to breathing difficulties during sleep.
Acromegaly: Acromegaly is a condition where the body produces too much growth hormone. This can lead to the enlargement of the soft tissues in the airway, making them more likely to collapse during sleep.
Neuromuscular disorders: Neuromuscular disorders, such as muscular dystrophy and multiple sclerosis, can weaken the muscles in the airway, making it more likely to collapse during sleep.
Congestive heart failure: Congestive heart failure can cause fluid to build up in the lungs, making it difficult to breathe. This can lead to breathing difficulties during sleep.
Stroke: A stroke can damage the brain centers that control the muscles in the airway, leading to breathing difficulties during sleep.
Lifestyle habits
Lifestyle habits can also contribute to sleep apnea. These habits can affect the muscles and tissues in the airway, making them more likely to collapse during sleep. Some of the lifestyle habits associated with sleep apnea include:
Smoking: Smoking can irritate the tissues in the airway, leading to inflammation and swelling. This can make it more difficult to breathe during sleep.
Alcohol consumption: Alcohol relaxes the muscles in the airway, making them more likely to collapse during sleep.
Sedative use: Sedatives, such as sleeping pills and tranquilizers, can relax the muscles in the airway, making them more likely to collapse during sleep.
Sleeping position: Sleeping on your back can cause the tongue and soft tissues in the airway to fall back, obstructing the airway and causing breathing difficulties during sleep.
Conclusion
Sleep apnea is a common disorder that affects sleep, quality of life, and long-term health. If you are concerned that you may be experiencing sleep apnea, arrange an evaluation by a board-certified sleep physician. After appropriate assessment, treatment may help to avoid serious consequences.
