Obstructive sleep apnoea (OSA) is increasing in parallel with the worldwide rise in obesity. Recent studies suggest that moderate to severe OSA (defined as an apnoea–hypopnoea index, AHI, >15 events/h of sleep) affects more than 25% of the adult population.1, 2 The population‐based Wisconsin Sleep Cohort study found that ecological weight gain of 10% increases the risk of developing OSA and results in about a 30% increase in the severity of OSA when it is present.3 The body mass index (BMI) of OSA patients presenting to sleep clinics is typically between 30 and 40 kg/m2.
