Sleep Apnea Symptoms And Risks
With sleep apnea the muscles located in the back of the throat relax and obstruct the airway cutting off your breath
. Because the muscles in the back of the throat also support the uvula, the tonsils and the tongue itself any of these can also become an obstructive source. This is the most common type of apnea and is called obstructed sleep apnea.
Sleep apnea is a sleep disorder that consists of pauses in breathing during sleep that involves the sleeping person missing one or more breaths repeatedly throughout night. The shortness of breath can cause low blood oxygen saturation and increased neurological activity, which can lead to daytime sleepiness and fatigue due to the lack of restful sleep.
Sleep apnea is a broad term, since there it has subtypes. The most common is called sleep apnea. It is considered as an obstructive disorder since it results from the obstruction of the respiratory system that leads to difficulty in breathing. Another form of apnea is called central sleep-apnea, wherein the damage is in the area of the brain which controls breathing during sleep. There is also something called mixed apnea. As the name suggests, it is a combination of the symptoms of obstructive and central apnea.
Snoring can be a sign of sleep apnea. We should keep in mind that not all episodes of snoring are indicative of sleep apnea or any other potentially life-threatening malady. Snorer with serious snoring problems must be aware of the symptoms obstructive sleep apnea and its risks. It is important to distinguish between serious and mild sleep apnea.
Complications that are associated with central sleeping issue are: daytime fatigue and cardiovascular problems. Central sleeping issue is associated with repeated awakening throughout your sleep cycle. These repeated awakening make it virtually impossible to get a good night's sleep; therefore, daytime fatigue is usually the result and a complication of central sleeping issue.
Mixed sleep disease is usually diagnosed when the patient not only has physical blockage of the airway, but also experiences reduced or erratic brain activity in the area that controls breathing. This can cause treatments that are used to reduce one of the normal types of sleep apnea to be ineffective. Treating the symptoms of obstructive sleep apnea, for instance, may still result in the brain being unable to control breathing properly. The patient, while treated for obstructive sleep disease, is still suffering from central sleep apnea.
Sleep apnea causes a person to experience all sorts of signs and symptoms, but he may not necessarily be able to remember what these signs and symptoms are, primarily because they happen mostly at night while the person is supposed to be sleeping. Because of this, many people who suffer from sleep apnea are not even aware of their situation, which makes it even more dangerous since apnea can lead to all sorts of other health problems when left undiagnosed and untreated for a very long time.
Unfortunately, only a few patients with sleep-related breathing disorders succeed in maintaining their weight reduction after dieting. One study found that only 3% of patients with OSA who had a significant improvement in their sleep apnea symptoms after dieting were able to maintain their weight loss after 5 years. In fact, many patients regained all the weight they lost and added more.
Sleep apnea is generally categorized as one of three types. Obstructive sleep apnea involves a physical blockage of your airway; central sleep apnea means that your brain is failing to send the proper "breathe now" signals to your respiratory system; and mixed sleep apnea is a combination of the two. Obstructive is by far the most common of the three and mixed is exceedingly rare.
The symptoms of sleep apnea are loud snoring, hyper somnolence (excessive daytime sleepiness), and restless sleep.
Snoring is a sign of upper-airway obstruction to a critical degree. During snoring the inability to inhale oxygen and exhale carbon dioxide upsets the balance of oxygen and carbon dioxide in the blood. The brain senses the low level of oxygen and increased levels of carbon dioxide and sends a signal to resume breathing and cause an arousal. The frequent arousals inhibit the normal sleep cycle and results in fragmented sleep. This makes the patient feel very sleepy during the day and complain of a very unrefreshing sleep at night.
