Here’s another study that strengthens the connections between the dots in my sleep-breathing paradigm. About 87% of obese type II diabetics were found to have undiagnosed obstructive sleep apnea. Most diabetes studies give the impression that having diabetes can lead to obstructive sleep apnea due to gradual weight gain, but what I propose is that having even very mild sleep-breathing problems can predispose to elevated glucose levels, insulin resistance, and weight gain. I talk about the specific mechanism in my book, Sleep, Interrupted. What I want to emphasize is the fact that an underlying sleep-breathing condition is what can predispose you to obesity AND diabetes, not the other way around.
