Secondary diabetes is diabetes caused by another condition or a medical treatment. Dozens of conditions can damage the body’s complex regulation of glucose and insulin levels. For example:

• Pancreatitis, cystic fibrosis or hemochromatosis can disrupt pancreas function.
  
  
• Endocrine disorders such as acromegaly or Cushing’s syndrome may alter the production of hormones.
  
  
• Certain drugs and chemicals promote insulin resistance or hyperglycemia.
  
  
• Genetic mutations can interfere with the body’s ability to produce and use the hormones that control glucose.

Unlike most forms of diabetes, secondary diabetes is sometimes temporary. However, some cases of secondary diabetes, such as those resulting from a total pancreatectomy, will be chronic.

Secondary diabetes is similar to other forms of diabetes in its signs and symptoms, as well as its diagnosis. However, the primary condition may mask indicators of secondary diabetes in some cases. Patients who experience possible symptoms of diabetes, such as unexplained weight loss and excessive urination and thirst, are advised to see their physician. The disease is diagnosed with glucose tests.
