OSA is obstructive sleep apnoea, a common cause of severe snoring in middle aged men. Very loud snoring is the commonest sign of the condition. Sufferers are often told by their sleeping partners that they stop breathing while they are asleep. They then splutter, wake up and carrying on breathing and snoring.
The abdomen may see-saw with the chest due to airway obstruction. Air shunts back and forth within the chest and doesn't leave the body whilst this is happening.
Affected individuals often find that they are very tired during the day. This is due to their repeated waking at night, to the point that they fall asleep during meetings, at work or whilst driving.
Risk factors include diabetes, smoking, middle age, being a man, alcohol consumption and large collar size. Sufferers must visit their doctor for investigations to find out whether they have the condition. This is so that risk factors can be addressed and the problem treated. This is because it can cause strokes and heart attacks, both of which can reduce the quality and duration of life.
