A study finds that seniors with sleep breathing issues often have high blood sugar and may be almost twice as likely as sound sleepers to develop type 2 diabetes, reports Reuters.

“Recent evidence suggests that diabetes patients have a higher prevalence of sleep disturbances than the general population,” lead author Linn Beate Strand said by email.

“However, less is known about whether symptoms of sleep-disordered breathing increase the risk of developing type 2 diabetes later, especially in older adults,” said Strand, of the Beth Israel Deaconess Medical Center in Boston.
