Sleep Apnea

Obstructive Sleep Apnea (OSA) occurs when your airway temporarily collapses during sleep. You continue to make efforts to breath but are unable to move air in and out of your lungs because of the obstruction at the back of your throat. During the collapse, which can last from 10 seconds to over a minute, your breathing muscles continue to work with a progressive effort until you awaken and resume normal breathing. After a few breaths, your oxygen levels return to normal. You fall back to sleep and the airway obstruction occurs again. This cycle may continue throughout the night, disrupting your normal sleep pattern.  As a result, you may complain of un-refreshing sleep and excessive daytime sleepiness.

What is the cycle of Obstructive Sleep Apnea?

cycle-of-ocaThe cycle of OSA starts with snoring and continues until the airway collapses or closes off. The person tries to breathe but is unable to get air into their lungs through the collapsed airway and an apnea (cessation of breathing) occurs. The brain realizes that it is not getting enough oxygen and fresh air so it wakes the person from a deep level, to a lighter level, of sleep. The airway then opens and normal breathing resumes. The person falls back into a deeper sleep, begins snoring again and the cycle repeats.

 

How common is sleep apnea?
  • 1 in 15 people have moderate to severe OSA (Young et al. JAMA 2004)
  • 9% women and 25% men in the middle-aged working population have OSA (Marshall et al. Sleep 2008)
  • Sleep apnea is as common as diabetes and asthma.
  • Most OSA sufferers remain undiagnosed and untreated.
  • 50% of patients with Type II Diabetes have OSA
  • 35% of patients with high blood pressure have OSA 6
What causes the airway to collapse during sleep?
  • Extra tissue in the back of the airway such as large tonsils
  • Decrease in the tone of the muscles holding the airway open
  • The tongue falling back and closing off the airway
  • Abnormal anatomy such as a recessed jaw
What are the common signs and symptoms?

For many sleep apnea patients, it is usually their partner or family members that suspect something is wrong.  They may complain about their snoring and apparent struggle to breath at night. The typical sleep apnea patient may have the following symptoms:

  • Excessive daytime sleepiness (EDS)
  • Loud irregular snoring
  • Witnessed apneic or choking periods
  • Morning headaches
  • Frequent awakenings during the night
  • Rapid onset of sleep
  • Leg cramps
  • Weight gain
  • Sleepiness while driving
  • Frequent need to urinate at night

Some patients have reported dry nose and throat while using this treatment. You may also experience some gastric bloating or irritation of the skin on your face.

Mouthpieces If you have a mild sleep apnea a mouthpiece, also sometimes called an oral appliance, may be the proper solution for you. A dentist or orthodontist can make a custom fit appliance that helps keep your lower jaw and tongue positioned to keep your airway open. You may need to visit your doctor periodically to get adjustments to the mouthpiece so that it will fit better. CPAP Treatment Continuous Positive Airflow Pressure (CPAP) is a common treatment for sleep apnea, especially in moderate to severe cases of obstructive sleep apnea. The CPAP is a machine hooked up to a mask that provides a consistent stream of airflow that keeps your airways open while you sleep and ensures you are getting enough oxygen. It is important that your CPAP machine is correctly set for your comfort. If it is incorrectly set, you may experience some bloating or discomfort wearing the mask. Some people have reported having headaches, dry mouth, irritated skin on the face, or a dry or stuffy nose. If you are experiencing any of these effects, speak with your doctor about tuning the machine to reduce these discomforts.

Keeping a steady sleep schedule will reduce the episodes of apnea, particularly when you are getting enough sleep. Sleep on your side. Try to avoid sleeping on your back as gravity increases the chance of your soft tissues dropping to obstruct your airway Prop your head up. Raise the head of your bed by approximately 4 to 6 inches to help keep your airway open Keep your nasal passages open. Help relieve allergies or nasal blockages with breathing strips, nasal sprays, or a saline spray.   Throat Exercises to Reduce Snoring Stronger throat muscles may help reduce the severity of snoring.  Try these exercises to strengthen the muscles and keep them from collapsing Hold your tongue flat against the bottom of your mouth and brush the top and sides with a toothbrush.

Dangers & Seriousness of Sleep Apnea

Sleep apnea is an illness that needs to be taken seriously. It impacts more than your ability to get a good night sleep. Long term effects can be severe if it is left untreated. Studies have shown that those with sleep apnea were three times more likely to die sooner than those who did not have it or received treatment. Long Term Effects of Untreated Sleep Apnea The consequences of sleep apnea range from both annoying to life threatening. Symptoms range from depression, irritability, sexual dysfunction, increased weight gain to learning and memory difficulties. You may find yourself falling asleep at work, on the phone or even while driving. In fact, untreated sleep apnea patients are 3 times more likely to have automobile accidents. If left untreated, sleep apnea can cause any one of these conditions: Weight gain. Increased fat deposits around the neck can increase your risk of sleep apnea but if you already have sleep apnea it can lead to additional weight gain. Sleep apnea impairs your body’s endocrine system. This disruption causes the release of the hormone ghrelin, which makes you crave sweets and carbohydrates. High blood pressure. When you’re sleep is constantly interrupted, it places your body in a fight or flight mode that causes your blood pressure to spike. Over time this leads to a consistent higher blood pressure Heart disease. Sleep apnea causes a lower amount of oxygen to be in your bloodstream. This impacts brain function and ability to regulate the flow of blood. Atrial fibrillation – heartbeat rhythm problems – is also associated with obstructive sleep apnea. These issues cause people... read more

The Three Types of Sleep Apnea

What Kinds of Sleep Apnea are There? There are three types of sleep apnea, obstructive, central, and complex. If you have obstructive sleep apnea, it is caused by the muscles of the your throat relaxing while sleep. When this occurs, the muscles provide less support to the tonsils, the uvula (the triangular piece of tissue that hangs from your soft palate), and the side walls of the throat. When these areas get less support, it narrows your airway and you can’t get an adequate breath in. If you have central sleep apnea, your brain is not sending the correct signals to the muscles that control your breathing. This causes you to have shallow breathing or to stop breathing for intervals of time.  This type of apnea is more common after a stroke, with heart disease, or with narcotic or sedative use. Complex sleep apnea is a combination of the obstructive and central forms. Risk Factors for Sleep Apnea Anyone can get sleep apnea including women, men, and children. There are a number of things that do increase your risk of sleep apnea such as: Age. Sleep apnea tends to be more common in adults older than 60 Excess weight. Thin people develop sleep apnea as well but anyone who has excess fat around the upper airway is at increased risk of having their breathing obstructed Neck thickness. Anyone who has a thicker neck tends to have a narrower airway, making it easier to become blocked Narrowed Airway. If you have inherited a naturally narrow throat or your tonsils or adenoids are enlarged, this can block your airway Smoking. Anyone... read more
