Sleep apnea, snoring and Obesity
What is sleep apnea?
Sleep apnea, also known as obstructive sleep apnea, is a sleep disorder where your throat is partially or completely obstructed during sleep. When these obstructions occur, it can stop breathing from anywhere from 10 seconds to a minute or more1.
During sleep, you wake up briefly, then fall back asleep. These incidents can happen hundreds of times a night.
What is the link between obesity, sleep apnea, and snoring?
One of the major contributors to sleep apnea and snoring are obesity.
It’s estimated that 58% of moderate-to-severe sleep apnea is caused by obesity2.
The reason is mainly because higher fat levels and decreased muscle activity in the upper respiratory tract narrow the airway3. This can also contribute to snoring as it makes your throat narrower and allows it to vibrate more easily. The narrower the throat, the louder you snore4.
What are the causes of sleep apnea?
Sleep apnea can occur at any age, although in children it’s usually because of large tonsils or adenoids5. It can run in families and can be affected by the size and positioning of your neck, jaw, tongue and tonsils. It is more likely to occur in men than women6.
You are also more likely to suffer from sleep apnea if you smoke7, sleep on your back and use sedatives, including alcohol8. Hormone conditions such as hypothyroidism9 can also increase the risk of sleep apnea.
What are the complications of sleep apnea?
Sleep apnea can increase your risk of other diseases, including heart disease, high blood pressure, stroke and diabetes. Lack of sleep can also lead to low mood and irritability.
Studies have found that people with sleep apnea are more likely to be involved in car accidents10
What are the treatments for sleep apnea?
There are no cures for sleep apnea but fortunately, it is a treatable condition. The first advice doctors often give is to lose weight11. Decreasing alcohol consumption in the evening and adjusting the sleeping position can also help11.
Other sleep apnea treatments include a nasal continuous positive airway pressure machine which uses gentle pressure and a mask to keep your airway open overnight. There is also a mandibular advancement device or oral appliance, which is like a mouth guard. It’s fitted by a specialist dentist and helps keep your airway open11.
It’s advisable to talk to your doctor about sleep apnea treatments and what might be best in your circumstances.
