Abstract Acromegaly is a rare, chronic disease that is, in more than 95% of cases, caused by growth hormone (GH)-secreting pituitary adenoma. Overproduction insulin-like factor-1 (IGF-1) due to GH hypersecretion leads various clinical features characterized somatic overgrowth, physical changes, multiple comorbidities, and increased mortality. The average age at diagnosis 40 50 years, with no se...
