What Is Sleep Apnea?

Sleep apnea is a potentially harmful medical condition where your breathing repeatedly starts and stops throughout your sleep. This is what is sleep apnea. One of the main symptoms of sleep apnea can be loud snoring and experiencing fatigue in the daytime. These breathing lapses can wake you up with a choking sensation or leave you gasping for air. There are mainly three types of sleep apnea;

• Obstructive sleep apnea
• Central sleep apnea 
• Complex sleep apnea syndrome 

Obstructive Sleep Apnea 

Obstructive sleep apnea (OSA) is when you experience a blockage in the back of your throat that obstructs the airways and causes loud snoring. The most common response in people suffering from OSA is that they may wake up gasping while making choking noises.

Central Sleep Apnea

In central sleep apnea (CSA), the communication between the brain and muscles responsible for breathing is disrupted. Therefore, people suffering from CSA experience shallow breathing with frequent pauses during their slumber. 

Complex sleep apnea is a condition where you experience a combination of both OSA and CSA. 

What causes sleep apnea?

Several factors can obstruct the airways. 

• Muscles and tissues in the mouth and throat become relaxed
• Nasal congestion
• Underlying medical disorder 
• Fat storage near the airways 
• Thick throat tissues 

These factors can result from genetics, colds, allergies, thyroid problems, obesity, heart or liver failure, and swollen or large tonsils. 

Symptoms of Sleep Apnea

Sometimes, you may notice the signs of sleep apnea of both OSA and CSA, making it harder for you to understand the type of sleep apnea you suffer from. However, the most common sleep apnea symptoms;

• Snoring loudly 
• Your partner may notice that you have stopped breathing for a while during your sleep
• You wake up gasping for air
• Waking up with a dry mouth 
• Insomnia
• Experiencing excessive daytime sleepiness
• Frequent headaches
• Unable to concentrate

Sleep Apnea in Children

Paediatric sleep apnea is when children go through the symptoms of sleep apnea due to narrowing or blockage of the upper airways. However, there are differences between adult and paediatric sleep apnea. Adults experience excessive daytime sleepiness as a symptom, whereas children display behavioural problems. 

In children, sleep apnea usually occurs due to large tonsils or adenoids. This ailment can be combated with timely diagnosis and treatment, and adverse effects on growth and cognitive behaviour can be averted.
