Understanding Acromegaly: Causes and Symptoms
Is Acromegaly Genetic? Unraveling the Truth In order to explore the genetic factors of acromegaly, it is essential to first understand this rare hormonal condition.
Acromegaly is a disorder that occurs when the pituitary gland produces excessive amounts of growth hormone (GH). This excess GH stimulates the production of insulin-like growth factor-1 (IGF-1), leading to the characteristic symptoms of acromegaly.
Causes: The primary cause of acromegaly is typically a non-cancerous tumor called an adenoma that develops in the pituitary gland. These tumors are usually benign and do not spread to other parts of the body. However, they can cause the pituitary gland to produce excessive amounts of GH, leading to the development of acromegaly.
Symptoms: Acromegaly is characterized by gradual and progressive changes in the body. Some of the common symptoms include:
Enlargement of the hands and feet, with thickened fingers and toes
Coarsening of facial features, such as a protruding jaw and enlarged nose
