The most common causes of secondary diabetes are as follows:

  • Diseases of the pancreas that destroy the pancreatic beta cells (eg, hemochromatosis, pancreatitis, cystic fibrosis, pancreatic cancer)

  • Hormonal syndromes that interfere with insulin secretion (eg, pheochromocytoma)

  • Hormonal syndromes that cause peripheral insulin resistance (eg, acromegaly, Cushing syndrome, pheochromocytoma)

  • Drugs (eg, phenytoin, glucocorticoids, estrogens)
