Diabetes is a chronic disease with no cure as of 2010 but a lot of research is underway. It is associated with an impaired glucose cycle, altering metabolism. Management of this disease may include carefully managing diet, exercising, taking oral diabetes medication, using some form of insulin, maintaining proper circulation in extremities and may be further complicated by other external factors such as stress, illness, menses, injection site scarring, and other physiological factors unique to individual patients.
