An investigator at McGill University in Montreal says there's evidence to suggest that sleep apnea therapy can reduce the risk of developing diabetes. In a small study involving 39 overweight middle-aged people considered at risk for developing diabetes, the group being treated for sleep apnea demonstrated lower levels of the stress hormone norepinephrine as well as lower blood pressure than the placebo arm. "Our study showed that CPAP in patients with prediabetes can lower their risk of progressing to diabetes when CPAP is used for eight hours, a full night's sleep," concluded the study's lead author, Sushmita Pamidi.
