Breathing-Related Sleep Disorder is a condition in which sufferers experience difficulty sleeping due to abnormal breathing. There are three main types of Breathing-Related Sleep Disorder: obstructive sleep apnoea syndrome, central sleep apnoea syndrome and central alveolar hypoventilation syndrome.

The main symptom of the disorder is restless, constantly interrupted sleep, resulting in feelings of tiredness and lethargy during the day. This can lead to headaches, memory difficulties and insomnia. Long-time sufferers of Breathing-Related Sleep Disorder can become depressed because of this. Obstructive sleep apnoea, the most common of the three, is caused by an obstruction in the upper airway. This results in sufferers gasping during sleep and periods of loud snoring. These can last for up to thirty seconds. Central sleep apnoea is caused by the lungs temporarily ceasing to oxygenate the blood, which leads to interruptions in sleep, but not a major snoring problem. The main symptoms of central alveolar hypoventilation are extreme tiredness and insomnia.

Breathing-Related Sleep Disorder is commonly seen in overweight people. There are many serious problems that can develop from sleep apnoea including stroke, high blood pressure and diabetes. Heart failure, heart attacks and irregular heartbeats can also be dangerous consequences for those who do not seek treatment for Breathing-Related Sleep Disorder.
