Hyperpituitarism

Hyperpituitarism

Hyperpituitarism (pronounced: hi-per-pi-too-i-tar-ism) is a medical condition characterized by the excessive secretion of pituitary hormones by the pituitary gland.

Etymology

The term "Hyperpituitarism" is derived from the Greek words "hyper" meaning over or above, "pituita" meaning phlegm (which the Greeks believed to be produced by the pituitary gland), and "ism" denoting a condition or disease.

Causes

Hyperpituitarism is most commonly caused by noncancerous tumors in the pituitary gland known as pituitary adenomas. Other causes can include certain genetic disorders, hypothalamic disease, and excessive intake of certain medications.

Symptoms

The symptoms of hyperpituitarism can vary greatly depending on which hormones are overproduced. Common symptoms can include gigantism or acromegaly, Cushing's syndrome, hyperthyroidism, hyperprolactinemia, and hypogonadism.

Diagnosis

Diagnosis of hyperpituitarism typically involves blood tests to measure hormone levels, MRI or CT scan to identify any pituitary tumors, and a physical examination to assess for symptoms of hormone overproduction.

Treatment

Treatment for hyperpituitarism typically involves managing the underlying cause. This can include surgery to remove pituitary tumors, medication to reduce hormone production, and radiation therapy.
