Type 2 Diabetes and Sleep Disordered Breathing
People with type 2 diabetes have in increased risk of sleep disturbed breathing resulting in intermittent night time hypoxia and fragmented sleep. They are also up to 20 times more likely to suffer from obstructed sleep apnea.
Prior studies have suggested that poor sleep is related to a person’s risk of type 2 diabetes. If blood glucose levels are improved during the night, it reduces oxygen desaturation during sleep. A group of resesarchers in Spain found that type 2 diabetes and elevated fasting blood glucose are independent predictors of daytime sleepiness and poor sleep quality . This was a controlled study in which the majority of type 2 diabetics reported poor sleep. They reported additional symptoms such as peripheral neuropathy, restless leg syndrome and sleep apnea.
