What is Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea is a sleep disorder and potentially serious medical condition. OSA causes you to stop breathing for 20+ seconds many times throughout the night, anywhere from 40 to hundreds of times per night. Each time you stop breathing you rouse yourself out of sleep to begin breathing again - this rousing prevents you from entering the deep, restorative stages of sleep. In the morning you will not remember rousing, though you will certainly feel the effects of not having any restful sleep!

The reason OSA causes you to stop breathing is because your throat becomes obstructed:

  • The breathing muscles in the back of your throat relax
  • This causes the back of your throat to collapse fully or partially
  • You collapsed throat, sometimes with the assistance of tonsils or tongue, blocks your airway
  • Your body rouses from sleep to wakefulness to resume breathing
  • You do not remember waking up in the morning

Each blockage/arousal cycle is called an apnea or apnea event. OSA can lead to moderate or catastrophic sleep deprivation, with well-known medical side effects.

OSA can be mild, moderate or severe depending on how many apneas you experience.

Obstructive Sleep Apnea Severities

Obstructive sleep apnea has different severities depending on how many apneas are experienced per hour. These guidelines area guidelines, meaning rough estimates of severity.

  • Mild: 5-14 apneas per hour of sleep
  • Moderate: 15-30 apneas per hour of sleep
  • Severe: 30+ apneas per hour of sleep

The important implication here is that even mild OSA causes you to rouse several dozen times per night in a BEST case scenario, but can be upward of 240 times per night or more.

Severe sleep apnea may cause more noticeable symptoms than mild OSA, and the treatments may be different as well, but the risk factors are generally the same for mild, moderate, and severe sleep apnea.

How to Identify Symptoms of OSA

Obstructive sleep apnea can go unnoticed for many years, especially in the case where you do not have a bed partner. A bed partner can be instrumental in identifying obstructive sleep apnea because the two hallmark symptoms of OSA are things that the OSA sufferer is not going to notice:

  • Repeated episodes of not breathing throughout the night
  • Chronic, loud snoring

If you are awake near someone with sleep apnea, the snoring and periods of not breathing are quite obvious. Beyond this, there are other symptoms that you will likely notice if you have OSA and can be very helpful telltale markers:Sleep-apnea-is-a-factor-in-many-eye-problems,-but-you-can-get-helpOSA is also associated with other medical diseases, such as above

  • Restless sleep
  • Morning headaches
  • Daytime fogginess
  • Severe daytime sleepiness
  • Chronic irritability
  • Depression/anxiety

It is likely that even if you don’t have a bed partner, someone will make you aware of your chronic snoring. If this is the case, you should pay attention to other symptoms to try and identify whether or not you simply have a snoring issue or if there are other causes at work.

Dangers of OSA

Risk of OSA are numerous and serious, and are caused because of chronic sleep deprivation. Some of the main risks are:

  • High blood pressure
  • Diabetes
  • Stroke
  • Heart disease
  • Depression
  • Reduced cognitive performance
  • Reduced stress management
  • Shorter life expectancy
  • Lower quality of life
  • Lower performance in many areas of life

How to Treat OSA

For most cases of OSA, CPAP therapy is what is used to treat OSA. However, CPAP therapy may be prescribed only after other options are explored [resmed] – these other options are dependent on your existing biological makeup and habits, and include:

  • Life style changes, in the case of unhealthy eating, drinking, tobacco use, and exercise habits
  • Losing weight, in the case where you are overweight
  • Changing sleep position, in the case where you sleep on your back
  • Medication changes, in the case where you take certain medications
  • Surgery (rare), in the case where anatomy is the cause

CPAP therapy is a technique used via a CPAP machine. A CPAP device/machine stands for Continuous Positive Airway Pressure and is the primary component of CPAP therapy and sleep apnea treatment. A CPAP machine is a small, rectangular box with a motorized fan inside and an adjacent humidifier. The small fan inside delivers gentle, positive pressure through a connected hose to the breathing mask. The result, no more lapses of breathing at night because the positive air pressure keeps your airway open.
