How is acromegaly diagnosed?

When a doctor notices signs or symptoms that suggest acromegaly, he or she will order one or more tests to confirm the diagnosis. These may include:

  • A blood test for elevated IGF-I levels
    • This is the best way to diagnose acromegaly. High IGF-I levels almost always indicate acromegaly.
  • A blood test for elevated growth hormone (GH) levels
    • A series of blood samples are taken over several hours. This test requires that the patient avoid food overnight, skip breakfast, and drink a glucose solution on the morning of the test.
  • A magnetic resonance imaging (MRI) scan of the head
    • This test allows the physician to look for a pituitary tumor that may be causing excess GH production.

What happens if acromegaly is not controlled?

If acromegaly is not controlled, it can cause diseases, such as arthritis, diabetes, high blood pressure, and heart disease. Some of these diseases can even shorten your life.

The good news is that there are ways to control acromegaly and reduce some of the associated risks.
