Which condition causes symptoms based on the hormones affected?

Hyperpituitarism is a condition characterized by the excessive secretion of hormones from the pituitary gland due to various factors such as tumors or hyperplasia. The symptoms of hyperpituitarism arise directly from the excess production of specific hormones, which can lead to distinct clinical manifestations.

For example, if the pituitary gland produces too much growth hormone, it can cause symptoms like acromegaly or gigantism, depending on the age of onset. Excess prolactin can lead to galactorrhea, amenorrhea, and infertility. High levels of adrenocorticotropic hormone (ACTH) can result in Cushing's disease, characterized by weight gain, hypertension, and other glucocorticoid-related symptoms. Therefore, the clinical presentation of hyperpituitarism is highly dependent on the hormone that is overproduced, leading to a wide range of symptoms related to the specific hormonal imbalances affecting various organs and systems in the body.

In contrast, conditions like hypopituitarism, gigantism, and acromegaly, while related to pituitary function, do not encompass the broad range of symptoms resulting from hormone excess seen in hyperpituitarism. Hypopituitarism typically results in hormone deficiencies rather than
