Acromegaly, or Pierre Marie’s disease as it is sometimes called (after the first doctor to accurately describe the symptoms), is a hormonal disorder characterized by abnormal bone growth, enlarged hands and feet, and thickened, enlarged face. Learn more about this rare endocrine disease, its diagnosis and the different treatment options available.

Acromegaly is a hormonal disorder that is most often diagnosed late. This diagnosis difficulty is due to the gradual appearance of symptoms and physical changes that creep in insidiously over a long period. Sometimes the person seeks medical advice for the back (rachalgia) or joint (arthralgia) pain. Diagnosis can be more than 10 years after the first symptoms appeared.

The following tests confirm a diagnosis of acromegaly:

  • A blood test to confirm elevated insulin-like growth factor-1 (IGF-1) is considered the gold standard indicator of clinical activity of acromegaly.
  • Growth hormone suppression test with glucose to artificially increase the level of glucose in the blood (by drinking a sugary drink) and measuring GH levels. In health individuals, the increased blood sugar depresses growth hormone levels, while in acromegaly growth hormone depression will be absent and the GH level will remain constant.
  • Scan or magnetic resonance imaging (MRI) to pinpoint the pituitary tumor.
