Insomnia, obstructive sleep apnea, or daytime sleepiness is linked to insulin resistance

This article discusses research showing that patients with insomnia, obstructive sleep apnea (OSA), or excessive daytime sleepiness are more likely to have insulin resistance. This is no surprise to me, as research has shown a link between OSA and diabetes before. But this research may prompt primary care physicians to test their patients for diabetes if they also experience insomnia or daytime sleepiness, or have known OSA.
