Sleep is meant to recharge and refresh your mind and body. However, for many people, sleep doesn’t bring the rest their body needs. Loud snoring, interrupted breathing, and frequent waking can turn your sleep into a frustrating experience.
No matter how long you stay in bed, you still wake up tired, drained, and unable to perform at your best throughout the day.
Uninterrupted sleep can be frustrating at times, especially when you don’t understand what is happening. You may think you are just a “light sleeper” or that tiredness or staying lethargic are a part of daily life. But, sometimes, the real reason is Sleep Apnea.
Now, let’s understand what Sleep Apnea is.
Sleep Apnea is more than just snoring. It is a sleep-related breathing disorder that can hamper your sleep cycle, affect your breathing pattern, lower your oxygen levels, and take a negative toll on your overall health, if left untreated for a long time.
But, The good news is that with the right sleep apnea diagnosis and treatment, most of the people can sleep better, breathe comfortably, and feel active throughout the day.
In medical terms, it is a condition where your breathing repeatedly stops, becomes shallow, or gets interrupted while you sleep. These are the frequent pauses that can happen many times during the night. This can happen so quickly that you may not remember it the next morning.
The problem of sleep apnea can affect both adults and children, and it is a condition that should not be ignored at any cost. It is treatable, but even after a proper medical evaluation. After knowing what sleep apnea is, this blog will walk you through sleep apnea symptoms, sleep apnea treatment, sleep apnea causes, types of sleep apnea, and sleep apnea diagnosis.
Sleep Apnea symptoms can be easy to miss as many of them happen while you are asleep. In fact, many people live with this problem for years without even realising it.
The symptoms differ during the day and at night.
First, let’s start with Nighttime symptoms
Some of the common nighttime symptoms of sleep apnea are:
Snoring is one of the most common warning signs, but not everyone who snores has sleep apnea. At the same time, not everyone with sleep apnea snores loudly. That’s the reason a proper sleep diagnosis is important.
Many people blame stress, age, or a busy lifestyle. But if poor sleep and tiredness persist for a longer period of time, sleep apnea may be the reason.
After, knowing the symptoms, let’s know its types
There are different types of sleep apnea, and understanding the type is important because treatment for each one is different in one way or another.
1. Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea, also known as OSA is the most common type. It happens when your upper airway becomes partly or completely blocked during sleep. The symptoms for this type are basically loud snoring, stoppage in breathing, waking up gasping, or feeling extremely exhausted during the day.
OSA is commonly treated with CPAP therapy, lifestyle changes, oral appliances, or in some cases, even surgery.
2. Central Sleep Apnea (CSA)
Central sleep apnea is less common than obstructive sleep apnea. In this, the problem is not usually a blocked airway. Instead, the brain does not send proper signals to the muscles that control breathing. It needs a proper medical evaluation on time. The treatment depends on the main cause and the person’s overall health.
3. Complex/Mixed Sleep Apnea
Complex or mixed sleep apnea includes features of both obstructive and central sleep apnea.
In some people, central breathing pauses may appear after treatment starts for obstructive sleep apnea.
This type can be more cumbersome and may require close monitoring by a sleep specialist at the right time.
Now, let’s understand what causes Sleep Apnea.
Sleep apnea causes can vary, depending on the type of sleep apnea.
In obstructive sleep apnea (OSA), the main issue is blockage or narrowing of the airway during sleep.
This may happen because your throat muscles relax too much, the tongue moves backwards, or there is some extra tissue around your airway.
Some of the other possible causes that contribute to Sleep Apnea are:
In central sleep apnea, the main cause is related to how your brain controls breathing. It may be associated with heart conditions, stroke, nervous system disorders, high altitude, or certain medications.
Sometimes, sleep apnea has more than one contributing factor. This is why its treatment is personalised rather than symptom-based.
Coming to how sleep apnea is diagnosed.
Sleep apnea diagnosis usually starts with a conversation with your doctor. You may be asked about the symptoms, sleep routine, snoring, daytime tiredness, medical history, and whether your partner noticed some pauses in breathing during sleep.
Your doctor may also examine your throat, nose, jaw, neck size, and other physical features that could affect your breathing patterns.
If sleep apnea is suspected, a sleep study may be recommended.
After the diagnosis of sleep apnea, it’s time to know about how this problem is treated.
Sleep apnea treatment depends on the type, severity, symptoms, and underlying causes.
Treatment may include CPAP therapy, lifestyle changes, oral appliances, surgery, or a combination of approaches available in the market.
CPAP Therapy
The first and foremost is the CPAP therapy. It is one of the common ways to treat Obstructive sleep apnea.
CPAP stands for Continuous Positive Airway Pressure. A CPAP machine sends a continuous flow of air through a mask while you are asleep. This gentle air pressure by the machine helps keep your airway open and prevents repeated breathing pauses.
Lifestyle Changes
Lifestyle changes may help reduce sleep apnea symptoms, especially if your problem is mild or when excess weight, alcohol, or sleeping position contributes to the problem.
Helpful changes may include:
Oral Appliances
Oral appliances are tailor-made dental devices that are worn during sleep. They help keep the airway open by moving the lower jaw or tongue into a better position.
Surgical Treatments
Surgery may be considered when other treatments do not work or when there is a complete physical blockage contributing to sleep apnea.
Some of the most common Surgical options may involve:
Sleep Apnea may sound confusing and exhausting. You may wake up tired, hear complaints about your snoring from your partner, or wonder why you always feel lethargic.
But, you are not alone, and you don’t have to keep living your life this way
The right sleep apnea treatment can help you breathe better, sleep more peacefully, and feel more active in your daily life.
If you suspect sleep apnea, speak with your doctor or sleep specialist. A proper sleep apnea diagnosis can give you answers, relief, and a clear path to move forward.
