What Is Sleep
Apnea
by Scott Fromherz, MD
Are
you feeling sleepy all the time? Do you snore? Is your doctor
having a difficult time treating your high blood pressure? If
you answered “yes” to any of these questions, then you might have
Sleep Apnea (also called Obstructive Sleep Apnea or OSA).
Sleep
Apnea is a condition involving pauses or decreases in breathing
during sleep. It is usually due to airway collapse. This collapse
occurs in the nose and/or the throat – anywhere from where air
enters the nostrils to the back of the tongue. Imagine a straw
collapsing when trying to suck on a thick milkshake. Frequently,
this airway collapsibility problem is inherited and starts in
childhood. In the daytime, it is not a problem because there is
good muscle-tone in the airway and the brain monitors breathing.
But at night, the throat muscles become relaxed and the brain
is not as attentive to the airway. So on inhalation, the airway
walls can either completely collapse or significantly narrow.
This is a problem because 1) the body must struggle to breathe
and 2) the brain has to “wake up” to reopen the airway.
These
frequent awakenings lead to fragmentation of nighttime sleep.
You may not remember them because they are so short. In fact,
patients with sleep apnea can wake-up more than 30 times an hour
and think that they slept uninterrupted through the night. Since
sleep must be continuous and consolidated in order to be restorative,
a number of cognitive problems can occur with sleep fragmentation:
daytime sleepiness, memory problems, concentration difficulties,
emotional instability, irritability, slowed reaction time, and
most importantly, an increased risk of motor vehicle accidents.
There
are also cardiovascular consequences of this constant “struggling
to breathe.” This puts a strain on the heart and blood vessels,
leading to increased risk of high blood pressure, heart disease
and stroke.
Finally,
there are social implications to Sleep Apnea. The snoring associated
with sleep apnea can disrupt the sleep of others. In fact, one
study showed that when a person treats his/her sleep apnea, the
sleep partner gets the equivalent of one hour more sleep per night.
Sleep
apnea is a progressive disease and often gets worse with age.
Weight gain, alcohol, and other sedating/relaxing substances exacerbate
it.
Who
Gets Sleep Apnea?
A
common misconception is that only overweight men that snore loudly
have sleep apnea, but the facts are:
Even
skinny women. Even children.
I
Think I Might Have Sleep Apnea, How Do I Find Out If I Have It?
Make
an appointment with your primary care physician, or if your insurance
allows it, go straight to a sleep specialist. If your physician
thinks you might have sleep apnea, then he/she can refer you for
a sleep study or comprehensive sleep evaluation.
How
Is Sleep Apnea Treated?
There
are four main categories of treatment for sleep apnea: Continuous
Positive Airway Pressure (CPAP), Surgery, Oral Appliances, and
Behavioral Modification. The most effective way to treat sleep
apnea is with CPAP. CPAP is a mask worn over the nose attached
by a hose to an air compressor. The air compressor gently and
quietly blows room-air into the nose, which “stents” the airway
open, preventing airway collapse. This is the most effective way
to treat sleep apnea, and all patients diagnosed with sleep apnea
should at least try it before considering other options.
Surgery
can be an effective way to treat sleep apnea. A number of different
procedures can be performed. These range from nasal septum repair
to jaw reconstruction. Talk to your doctor about whether surgery
is the right option for you.
An
oral appliance is a device made by a dentist or an orthodontist
designed to pull your lower jaw forward. By pulling your lower
jaw forward, the tongue is pulled away from the back of the throat.
If your airway obstruction is occurring behind the tongue, then
this can be an effective way to treat your sleep apnea. The treatment
of sleep apnea with oral appliance should be a coordinated effort
between the sleep physician, the dentist/orthodontist, and the
patient.
Behavioral
modifications can help in the treatment of sleep apnea, but are
usually the least effective. These include such techniques as
weight loss, sleeping on your side, and avoiding alcohol before
bedtime. None of these treatment options is ideal, but they all
can be useful in treating sleep apnea and resulting in more restful
sleep. With risks like heart attack and stroke, you should do
everything you can to get your sleep apnea under control.
If you think you have sleep apnea, contact your doctor or go to
a sleep center. It could be the best decision you ever made.
