Sleep Apnea is a condition marked by abnormal breathing during sleep. People with Sleep Apnea have multiple extended pauses in breath when they sleep.
These temporary breathing lapses cause lower-quality sleep and affect the body’s supply of oxygen, leading to potentially serious health consequences.
Sleep Apnea is one of the most common and undetected sleep disorders in Trinidad and Tobago. It can affect children and adults of both sexes, although it is more common in men.
Because of Sleep Apnea’s prevalence and potential health impact, it is important for people to be aware of what Sleep Apnea is and to know its types, symptoms, causes, and treatments.
There are three types of sleep apnea:
Because the underlying causes are distinct, there are important differences in the symptoms, causes, and treatments of OSA and CSA.
Obstructive Sleep Apnea is estimated to affect approximately 300,000 adults in the Trinidad and Tobago, but many cases are believed to go undiagnosed, which fits with studies that have found considerably higher rates of OSA. Precise prevalence is hard to determine because studies have used different criteria for diagnosing the condition. A consistent finding, though, is that OSA affects men more than women. It can occur in people of any age but is more common in older adults.
Central sleep apnea has been found to affect around 0.9% of adults over the age of 40. It is found much more frequently in men than in women.
As this data demonstrates, OSA is much more common than CSA. For this reason, when people talk about “sleep apnea”, they are generally referring to OSA.
Obstructive Sleep Apnea occurs when a person’s airway becomes blocked during sleep. Multiple factors have been found to increase the risk of blockage and OSA:
In CSA, breathing is affected in a different way than in OSA. Instead of an obstruction causing breathing lapses, the problem arises in how the brain communicates with the muscles responsible for respiration. In particular, the brain stem fails to adequately perceive the levels of carbon dioxide in the body, leading to breathing that is slower and shallower than it should be.
CSA is typically connected to an underlying medical condition. For example, a stroke, infection of the brain, or in rare cases a brain tumor may damage the brain stem. Pain medicines like opioids can also interfere with this normal process of breathing.
Heart failure is considered to be a risk factor for CSA, and CSA can also arise when a person’s oxygen levels are thrown off because they are at high altitude.
Sleep Apnea can lead to sleep deprivation from constant nightly interruptions and shallower overall sleep. Lack of sleep is associated with far-reaching health consequences that affect a person physically, mentally, and emotionally, and as a result, it comes as no surprise that sleep apnea has been tied to diverse health problems.
Because of how it affects oxygen balance in the body, untreated sleep apnea raises dangers for various types of cardiovascular issues including high blood pressure, heart attack, heart disease, and stroke.
If you have symptoms of sleep apnea, you should make sure to talk with a doctor. Without understanding the root causes of your sleep apnea, it is difficult to treat. When necessary, the doctor can recommend an overnight sleep study to analyze your sleep, including your breathing.
If a person is diagnosed with OSA or CSA, treatment is often effective at improving sleep and reducing the risks of long-term health complications. A doctor familiar with a patient’s situation is in the best position to address potential benefits and risks of treatments and make specific recommendations.
Lifestyle changes, such as losing weight, reducing the use of sedatives, and sleeping on your side, can resolve some cases of OSA. Another common treatment is the nightly use of a continuous positive airway pressure (CPAP) or bi-level positive airway pressure (BiPAP) machine. These devices push air through a mask and into the airway to keep it open during sleep.
Some types of mouthpieces that hold the jaw or tongue in a specific position are an option for people with certain anatomical features that trigger mild OSA. In addition, though usually not the first treatment option, surgery to remove tissue and expand the airway can be considered. Medications may be prescribed to help with daytime sleepiness in people with this symptom.
Treatment for CSA typically centers on managing the underlying condition, such as a brain infection, heart failure, or altitude adjustment, that causes disordered breathing. CPAP or BiPAP machines or supplemental oxygen may help some patients as well.
