I have read with interest the article published detailing the usefulness of screening questionnaires to detect obstructive sleep apnoea (OSA) in bariatric surgery patients . The data collection and results add to the literature suggesting that clinically significant OSA is both underdiagnosed in bariatric patients and that screening questionnaires lack sensitivity and specificity in this population; however, I found that the conclusion was a missed opportunity to advocate for integrating formal preoperative sleep studies for all bariatric surgical patients.
Despite the knowledge that bariatric surgery patients have a high risk of OSA, preoperative screening is infrequent . The finding that OSA is more common in bariatric surgery patients may be because patients who are at high risk of OSA are less responsive to typical weight loss interventions such as dietary counselling  and hence require a surgical intervention. A number of the diseases that bariatric surgery is attempting...
