A Definition Of Sleep Apnea Disorder As Well As Its Causes, Signs and Detection
Sleep apnea is just one of several common sleep disorders and the most widespread form of sleep apnea is known as obstructive sleep apnea and is a condition marked by periods in which breathing ceases while sleeping. On occasions this disorder is called obstructive sleep apnea syndrome or sleep apnea syndrome.
In healthy people the muscles which work the upper part of the throat ensure that the air flow in and out of the lungs is steady and continuous. During sleep these muscles relax a little but still do their job properly. However those people who have sleep apnea often have airways which are narrowed so that when the throat muscles relax the airway partially or completely closes thereby no longer allowing for the passage of air to the lungs. Snoring and labored breathing resulting in a sleep apnea episode will then result.
In some individuals breathing can also cease completely during periods of deep (or REM) sleep and medical experts and researchers are nor clear about just why this happens. These periods during which breathing ceases can last for ten seconds or more in severe cases and are referred to as apneic events or sleep apnea episodes.
These apneic events result in a degree of awareness that you have ceases breathing and you subsequently struggle to breath again which is normally accompanied by choking, gasping or even snorting.
Thereafter it is normal to settle into a period of light sleep before the cycle of sleep apnea episodes starts again.
The effect is that an individual suffers from fragmented sleep which does not allow them the amount of rest that they require on a nightly basis. This in turn leads to a number of health problems including excessive daytime tiredness. One of the reasons for this daytime symptom is simply that the level of oxygen in the blood stream falls tremendously during an apneic event leading to a condition known as hypoxia.
It is most important to realize that a lot of individuals with sleep apnea are unaware that they have a problem and often it must be left to others to point out the problem. Sufferers are generally aware of being very tired throughout the day but do not always know why this is so.
The commonest warning signs of sleep apnea include loud snoring, waking in the morning and still feeling tired, headaches in the morning, problems with memory, alterations in personality, falling asleep at inopportune times, hypertension, excessive levels of activity (in children only) and swelling of the legs in severe cases. The symptoms ought not to be disregarded because the danger of sleep apnea is very real.
The first step in diagnosing sleep apnea ought to a visit to the doctor who will read through your medical history and examine your mouth, throat and neck for signs of any growths or abnormalities. If your doctor suspects that you have sleep apnea he will refer you for a sleep study and what is called a polysomnogram (or PSG). This test records eye movement, brain waves, breathing rate, muscle activity, oxygen levels in the blood, heart rate and the quantity of air that is being both exhaled and inhaled during sleep.
Sleep apnea is an all too common sleep disorder which frequently goes unrecognized but which can be very dangerous and which can also normally be effectively treated.
