Acromegaly is a hormonal disorder characterised by abnormal bone growth, enlarged hands and feet, and thickened, enlarged face.1 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. Some people have symptoms which develop over four to seven years or more before the diagnosis is made.2
The following tests confirm a diagnosis of acromegaly:

  • A blood test to measure the level of IGF-1 is measured if acromegaly is suspected.
  • 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 healthy individuals, the increased blood sugar decreases growth hormone levels. However in acromegaly growth the growth hormone level remains high.
  • Magnetic resonance imaging (MRI) scan to pinpoint the pituitary tumour
  • Eye and visual tests can assess if the tumour is pressing on the optic nerve.
  • If you are confirmed as having acromegaly, other tests will be needed to see if the tumour is causing a lack or excess of other hormones made by the pituitary gland.
  • Other tests may include chest X-ray, electrocardiogram (ECG), echocardiogram and CT scan.2
