Role of Sleep Apnea and Gastroesophageal Reflux in Severe Asthma.

Gastroesophageal reflux and obstructive sleep apnea syndrome are conditions that practitioners have been encouraged to evaluate and treat as part of a comprehensive approach to achieving asthma control. In this review, the author looks at the evidence linking these two conditions as factors that may impact difficult-to-control asthma and looks critically at the evidence suggesting that evaluation and treatment of these conditions when present impacts asthma control.
