Obstructive sleep apnea (OSA) is a common yet serious disorder in which obstruction of the throat (upper airway) causes breathing to repeatedly stop and start, resulting in fragmented sleep, sleep deprivation, daytime tiredness and leaving OSA patients liable to a number of health risks.
Curiously, although obesity is the strongest risk factor for developing OSA, weight loss – while it can improve the severity of OSA – rarely cures it.
