Studies have shown high prevalence (60-94%) of obstructive sleep apnoea (OSA) among patients undergoing bariatric surgery. Fifteen studies are published investigating the effect of bariatric surgery on OSA. All of them conclude a highly positive effect on OSA by bariatric surgery and weight loss. However these studies are biased by a huge number of drop outs. The drop out rate in the studies are around 60 percent. The Investigators state that the prevalence of OSA among patients undergoing bariatric surgery in Denmark is high.
