A sleep apnea mouth guard is also referred to as a mandibular advancement device. It is an oral appliance used primarily at night and is similar in appearance to a mouthguard. However, it gently assists in treating mild to moderate obstructive sleep apnea by moderately advancing the lower jaw to help eliminate the cause of […]
Sleep apnea is a sleep disorder where breathing repeatedly stops and starts during sleep. This occurs due to a blockage in the airway (obstructive sleep apnea) or a failure in the brain’s signals to the muscles that control breathing (central sleep apnea). These interruptions can last from a few seconds to minutes and often result in loud snoring or choking sounds. Sleep apnea leads to poor sleep quality and can cause excessive daytime fatigue, making it important to recognize and treat this condition to improve overall health and well-being.
There are three common types of sleep apnea:
Obstructive sleep apnea (OSA) is the most common type and occurs when the muscles in the throat relax excessively, causing a temporary blockage of the airway. This blockage can disrupt normal breathing and lead to pauses in breathing during sleep. OSA is often characterized by loud snoring, choking, or gasping sounds. Risk factors include obesity, large tonsils, and a thick neck. It can result in fragmented sleep, excessive daytime drowsiness, and an increased risk of heart disease and high blood pressure.
Central sleep apnea (CSA) is less common and occurs when the brain fails to send the appropriate signals to the muscles that control breathing. Unlike OSA, there is no physical blockage of the airway. Instead, CSA is caused by a problem with the brain’s respiratory control center. This type of sleep apnea often affects individuals with underlying medical conditions such as heart failure or stroke. CSA can lead to irregular breathing patterns and periods of no breathing during sleep, causing disrupted sleep and daytime fatigue.
Complex sleep apnea (CompSA), also known as mixed sleep apnea, is a condition where both obstructive sleep apnea (OSA) and central sleep apnea (CSA) are present. Initially, a person may experience obstructive sleep apnea, characterized by physical blockages in the airway. However, after beginning treatment for OSA, central sleep apnea can sometimes emerge. This occurs when the brain fails to send the correct signals to the muscles responsible for breathing. Effective management of complex sleep apnea requires addressing both types of apneas simultaneously. This often involves adjusting treatment approaches, such as using specialized machines, and regular monitoring to ensure both obstructive and central breathing issues are properly managed.
The severity of sleep apnoea depends on how often your breathing is interrupted, usually measured by the Apnoea-Hypopnoea Index (AHI). As a guide:
Normal sleep
Fewer than 5 interruptions per hour (AHI < 5)
Mild sleep apnoea
Between 5 and 15 interruptions per hour (5 ≤ AHI ≤ 15)
Moderate sleep apnoea
Between 15 and 30 interruptions per hour (15 < AHI ≤ 30)
Severe sleep apnoea
More than 30 interruptions per hour (AHI > 30)
Symptom | Specific Manifestations |
Loud Snoring | Frequent, loud snoring is a common symptom, especially in obstructive sleep apnea. It may be accompanied by choking or gasping sounds. |
Excessive Daytime Sleepiness | Persistent drowsiness, fatigue, or the need to nap during the day despite having a full night’s sleep can indicate sleep apnea. |
Pauses in Breathing | Observed by a partner, these pauses can last for several seconds and are often followed by choking or gasping sounds. |
Restless Sleep | Frequent awakenings, restless tossing, or thrashing during sleep can be signs of disturbed sleep due to apnea. |
Morning Headaches | Waking up with headaches may be related to the poor sleep quality and oxygen deprivation associated with sleep apnea. |
Difficulty Concentrating | Problems with memory, concentration, and cognitive function can result from interrupted sleep and lack of restful sleep. |
Irritability and Mood Changes | Increased irritability, mood swings, or depression can occur due to chronic sleep disruption. |
Dry Mouth or Sore Throat | Waking up with a dry mouth or sore throat can be due to breathing through the mouth during sleep. |
The causes of different types of sleep apnea vary. Below are the primary causes of the three most common forms of sleep apnea today.
Obstructive Sleep Apnea (OSA)
Excess Weight: Obesity increases fat deposits around the neck and throat, leading to airway obstruction.
Large Tonsils or Adenoids: Enlarged tonsils or adenoids can block the airway, particularly in children.
Anatomical Features: Structural abnormalities such as a deviated septum, a large tongue, or a narrow throat can obstruct airflow.
Relaxed Throat Muscles: During sleep, the throat muscles may relax excessively, causing the airway to collapse.
Central Sleep Apnea (CSA)
Medical Conditions: Conditions such as heart failure, stroke, or neurological disorders can affect the brain’s ability to regulate breathing.
Heart Disorders: Certain heart conditions can influence the brain’s control of breathing patterns.
Stroke or Brain Injury: Damage to brain areas responsible for controlling breathing can lead to CSA.
Complex Sleep Apnea
Combination of Factors: This occurs when a person initially has OSA, and treatment for OSA leads to the emergence of CSA. It involves a combination of both obstructive and central sleep apnea causes.
Several factors can increase the likelihood of developing sleep apnea. Understanding these risk factors can help in identifying individuals who may be more susceptible to the condition:
Obesity
Excess body weight, especially around the neck and abdomen, can increase the risk of sleep apnea. Fat deposits in these areas can obstruct the airway and contribute to breathing problems during sleep.
Age
The risk of sleep apnea increases with age. This is partly due to changes in muscle tone and airway structure that occur as people get older.
Gender
Men are more likely than women to develop sleep apnea, although the risk for women increases, particularly after menopause.
Family History
A family history of sleep apnea or other sleep disorders can increase susceptibility, suggesting a genetic component to the condition.
Anatomical Features
Certain physical characteristics can contribute to sleep apnea, including a thick neck, a large tongue, enlarged tonsils or adenoids, a deviated septum, or a small upper airway.
Smoking
Smoking can increase inflammation and fluid retention in the upper airway, which can contribute to the development and worsening of sleep apnea.
Alcohol and Sedatives
Consuming alcohol or using sedatives relaxes the muscles of the throat, increasing the likelihood of airway obstruction during sleep.
Medical Conditions
Certain health conditions, such as high blood pressure, heart disease, stroke, diabetes, and hormonal disorders, are associated with an increased risk of sleep apnea.
Posture
Sleeping on the back can exacerbate sleep apnea symptoms, as the position can lead to airway collapse or obstruction.
Ethnicity
Some studies suggest that certain ethnic groups may have a higher prevalence of sleep apnea compared to others.
Gender Differences
Women may develop sleep apnea later in life, especially post-menopause, due to hormonal changes that affect the airway.
Identifying and addressing these risk factors can help in the early detection and management of sleep apnea. If you have several of these risk factors and experience symptoms of sleep apnea, consulting a healthcare professional for evaluation and possible treatment is essential.
