Does medication thats used for asthma cause diabetes?

Steroids: Taking steroids (eg. Prednisone) will certainly bring on diabetes in susceptible people. Inhaled steroids will not. The stress of a chronic disease can also raise blood sugar. Otherwise, metabolic syndrome (abdominal obesity, hypertension, family history, abnormal blood lipids, Insulin resistance) are all risk factors for diabetes, and are often found in asthmatics.
