Brief Summary

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. The Investigators state that the effect of bariatric surgery is significant on severity of OSA. The Investigators state that we can perform a study without a huge number of dropouts.

Secondary Outcomes (3)

  • weight

    Change from baseline in weight at one year

  • Circumference of neck

    Change from baseline in Circumference at neck at one year

  • mean saturation during sleep

    Change from baseline in mean saturation during sleep at one year

Other Outcomes (1)

  • ESS score
