This insulin restriction, in turn, leads to further health problems—one study shows they are three times more likely to die of diabetes-related complications than those who follow their medication regimen.
Treating diabetes patients with eating disorders comes with unique, complex challenges, says Marcia Meier, a diabetes nurse educator at the Melrose
