Understanding Obstructive Sleep Apnoea (OSA)

Obstructive Sleep Apnea (OSA) is a sleep problem that many people face. It happens when you have trouble breathing during your sleep. Your throat is a little tunnel that air passes through when you breathe. With OSA, this tunnel sometimes gets blocked, like when something is in the way, and that disturbs your sleep. If you leave OSA alone, it can lead to serious health problems. So, it’s important to know what it is and what you can do about it.

What is OSA?

Obstructive Sleep Apnea (OSA) is a unique sleep disorder characterized by the intermittent cessation and resumption of breathing during sleep. Unlike other sleep issues, OSA primarily results from an obstruction in the throat, which can be likened to a partially open door repeatedly closing and opening throughout the night.

For patients with obstructive sleep apnea, this condition disrupts their sleep cycle and can have serious health implications. The American Academy of Sleep Medicine plays a crucial role in defining and standardizing diagnostic criteria and treatment protocols for OSA.

One prominent symptom of OSA is snoring, which often accompanies obstructive sleep events. When individuals with OSA sleep, their airway becomes partially blocked, leading to snoring as air struggles to pass through the narrowed passage. This persistent snoring is often a red flag for the presence of OSA.

Unlike central sleep apnea, where the brain fails to send proper signals to control breathing, OSA is more common among adults. It is estimated that a significant number of adults suffer from obstructive sleep apnea syndrome, and it’s essential to recognize the signs and seek appropriate treatment.

The management of obstructive sleep apnea involves various approaches, depending on the severity of the condition. One of the most effective treatments is Continuous Positive Airway Pressure (CPAP) therapy, where a machine delivers a steady stream of air to keep the airway open during sleep.

In cases of mild sleep apnea, lifestyle changes, such as weight loss and positional therapy (avoiding sleeping on the back), can significantly improve sleep quality and reduce the severity of OSA.

Surgical treatment options may be considered for patients with obstructive sleep apnea who do not respond well to non-surgical therapies. These surgeries aim to address the physical obstructions in the airway during sleep.

It’s worth noting that OSA is associated with an increased risk of metabolic syndrome, which includes conditions like obesity, high blood pressure, and abnormal cholesterol levels. Proper diagnosis and treatment of OSA can help manage and mitigate these associated health risks

Why Does It Matter?

Now, you might wonder, “Why should I care about OSA?” Well, if you have OSA and don’t take care of it, it can mess with your health. That’s why it’s important to notice the signs of sleep apnea and talk to a doctor if you think you have it. They can help you figure out what to do.

Symptoms

Symptoms of obstructive sleep apnea (OSA) occurring during sleep can be challenging for an individual to self-diagnose, often taking years before recognizing the symptoms and seeking medical advice.

Night-time Signs:

Some initial noticeable signs of OSA may include:

Experiencing excessive daytime fatigue:

OSA stands as the leading medical cause of extreme daytime drowsiness. Individuals with obstructive sleep apnea in adults might find themselves dozing off during mundane activities such as reading or watching television. To combat persistent sleepiness, they may resort to consuming caffeine.

Observations from others:

Typically, a loved one, caregiver, or bed partner becomes the first to detect signs of obstructive sleep apnea syndrome. They may report instances of loud, disruptive snoring or instances where the sleeper gasps, chokes, snorts, or ceases to breathe during sleep.

Loud snoring

Imagine snoring really loudly, like a chainsaw. That’s what it’s like for some folks with OSA.

Moving a lot during sleep

You might keep turning and shifting in your sleep, like a restless sleeper.

Waking up to pee often

You might find yourself needing to go to the bathroom more than usual at night.

Breathing through the mouth while asleep

Instead of breathing quietly through your nose, you breathe through your mouth, which can be a sign.

Daytime Signs

Waking up with a headache, dry mouth, or the urge to urinate could be indicative of underlying OSA. Morning headaches may persist for hours and occur frequently.

Feeling tired when you wake up

Even after a whole night’s sleep, you still feel tired, like you didn’t rest well.

Morning headaches

Sometimes, you wake up with a headache.

Dry or sore throat

Your throat might feel dry or scratchy when you wake up.

Feeling super sleepy during the day

You could feel extremely tired during the daytime, almost like you want to take a nap.

Trouble with memory or thinking

It might be hard to remember things or think clearly.

Problems with sex drive

Your desire for intimacy might decrease, which can be concerning.

The causes of obstructive sleep apnea primarily stem from the natural relaxation of the muscles encircling the throat during sleep. These muscles, which keep the airway open and aid in breathing during the day, tend to relax during sleep, potentially leading to the narrowing or closure of the airway, thereby restricting airflow.

In most cases, this narrowing of the airway during sleep does not pose any issues. However, in individuals susceptible to OSA, such as those with a naturally constricted throat, more pronounced narrowing can result in obstructions and unsuccessful attempts to inhale. Struggling to inhale against a closed or narrowed airway can lead to abnormal levels of oxygen and carbon dioxide in the blood, along with fragmented sleep.

Airway obstructions can be categorized as either hypopneas or apneas, depending on their severity. When airflow diminishes by at least 30% for a duration of 10 seconds or more, it is termed hypopnea. If airflow reduces by 90% or more for at least 10 seconds, it is described as an apnea.

A medical diagnosis of OSA may be made when apneas or hypopneas occur more than five times per hour and are either witnessed by a loved one or result in adverse health effects. Treatment for obstructive sleep apnea often involves the use of continuous positive airway pressure (CPAP) devices, prescribed after a sleep study or sleep apnea test conducted in a sleep center. Managing this sleep disorder may also include adopting sleep hygiene practices. For severe sleep apnea cases, a diagnosis of obstructive sleep apnea should prompt medical intervention and consideration of home sleep apnea test options for a more convenient assessment. Sleep medicine specialists play a vital role in the diagnosis and treatment of obstructive sleep apnea in adults.

Factors Increasing the Risk of Obstructive Sleep Apnea:

Age

The likelihood of developing OSA tends to rise with age, peaking around 60 to 70 years old before stabilizing.

Gender

Men and individuals assigned male at birth face the highest risk of OSA. For women and individuals assigned female at birth, the risk is highest during peri- or postmenopausal stages.

Body Mass Index (BMI) OSA risk increases with a higher BMI, which measures body fat based on height and weight.

Physical Features That Can Contribute to OSA:

Certain physical characteristics can make someone more susceptible to OSA, including:

A small or backwards-positioned lower jaw.
An enlarged tongue at its base.
Large tonsils.
A neck circumference exceeding 17 inches.
Excess fat around the throat.
Additional Risk Factors Under Study:

Some risk factors for OSA are still under investigation but may elevate the risk:

Cigarette Smoking

Smoking can raise the risk of OSA by up to three times compared to non-smokers or those who have quit.

Family History

Relatives of individuals with OSA are twice as likely to develop the condition. This heightened risk could result from shared anatomical traits, similar lifestyles, or a common environment.

Nasal Congestion

Having a stuffy nose can double the chances of experiencing OSA. Nasal congestion can occur due to various factors, including colds, sinus infections, or the flu.

Understanding these risk factors is crucial in identifying individuals who may be at higher risk of developing OSA, allowing for proactive measures and timely medical intervention when necessary.

Diagnosing Obstructive Sleep Apnea

To find out if you have obstructive sleep apnea (OSA), doctors follow these steps:

Medical History

They ask about your health history and nighttime/daytime symptoms. Sometimes, you might need to fill out a questionnaire. Your roommates or loved ones can also share observations.

Physical Exam

Doctors check for signs like obesity or physical features that can increase OSA risk.

Sleep Study

A sleep study confirms OSA. It involves spending a night in a sleep lab with sensors on your body to measure breathing, heart rate, and sleep stages. There are two types: full-night and split-night studies.

Home Testing

Some may qualify for a home sleep apnea test, which can be prescribed by a doctor. It’s like a simplified sleep study done at home.

Treating Obstructive Sleep Apnea

The main treatment is Positive Airway Pressure (PAP) therapy, which involves using a machine to keep your airway open while you sleep. There are three types of PAP therapy:

CPAP: A machine maintains a constant air pressure during both inhaling and exhaling.
BiPAP: This machine adjusts the air pressure between inhaling and exhaling.
APAP: The machine changes pressure based on your breathing patterns.

Behavior changes can also help:

Change sleeping position to avoid sleeping on your back.
Lose weight if necessary.
Avoid alcohol and certain medications that can worsen OSA.
For those who can’t use PAP therapy, doctors may recommend oral appliances, surgery, or medications.

Complications of Untreated OSA

Drowsy driving accidents.
Mental health changes like irritability and depression.
Cardiovascular problems like high blood pressure and heart disease.
Increased diabetes risk.
Nonalcoholic fatty liver disease.

Living with OSA

While OSA can’t be cured, treatment can greatly improve life. Follow these tips:

Connect with support groups for guidance.
Be cautious when driving or operating machinery.
Keep in touch with your doctor or sleep specialist.
Avoid substances that worsen OSA.
Inform all doctors about your OSA diagnosis.

Follow good sleep habits like avoiding caffeine at night and keeping your bedroom comfortable.
