Acromegaly is a condition that results from the overproduction of growth hormone, which is primarily secreted by the pituitary gland. In most cases, this excess growth hormone is caused by a benign tumor on the pituitary gland known as an adenoma. The overproduction leads to the abnormal growth of bones and soft tissues, particularly noticeable in the hands, feet, and face.

The role of growth hormone is to regulate growth and metabolism in the body. When present in excess, it can lead to various systemic effects, including enlarged extremities and facial features. Other symptoms of acromegaly may include joint pain, thickened skin, and various metabolic abnormalities.

The other hormones listed do not directly relate to the development of acromegaly. For example, vasopressin primarily plays a role in the regulation of water balance and blood pressure, while prolactin is mainly involved in lactation and reproductive health. Calcitonin is primarily associated with calcium metabolism. Thus, the only hormone linked to the development of acromegaly due to overproduction is growth hormone.
