Sleep disorder linked to obesity
An expert has said the NHS is struggling with sleep disorders related to obesity.
Dr Tom Mackay of the Royal Infirmary of Edinburgh has referred to a "tidal wave" of cases.
The number of people being referred for sleep problems in Scotland has risen 25% over the last three years with around 80% of patients overweight.
There are now more new cases of sleep apnoea being diagnosed than lung cancer and emphysema combined.
