Most patients have unrecognised signs and symptoms for many years and may be diagnosed through a dental examination or testing done for other reasons.Although their outward appearance may have altered, it is often the symptoms of complications that lead patients to seek medical care.

Diagnostic blood tests

The diagnosis can be confirmed with an Oral Glucose Tolerance Test (OGTT) or measurement of serum IGF-I levels (age and sex-adjusted). Although both growth hormone (GH) and IGF-I levels have been implicated as indicators of mortality, IGF-I is considered to be indicative of persistent clinical disease activity.2,3


Imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI) are used to determine the cause of GH overproduction and provide further confirmation of the acromegaly diagnosis.4
