What is hyperpituitarism?
The pituitary gland produces hormones that regulate many functions in the body. A person with hyperpituitarism has an overactive pituitary gland that leads to high levels of one of the pituitary hormones in the bloodstream. The most common cause of hyperpituitarism is a non-cancerous tumor of the pituitary gland. Hyperpituitarism is very rare.

What are the symptoms of hyperpituitarism?
The symptoms of hyperpituitarism depend on the hormone that is over-produced by the pituitary gland. Symptoms of hyperpituitarism may include hyperprolactinemia symptoms, Cushing's disease symptoms, acromegaly symptoms, and hyperthyroidism symptoms.

How does the doctor treat hyperpituitarism?
The treatment for hyperpituitarism depends upon which hormone is over-produced by the pituitary gland. Treatment for hyperpituitarism may include medications, surgery, and hormone replacement therapy.
