    Pituitary insufficiency


    If hypopituitarism is caused by a tumor, you may need surgery to remove the tumor, with or without radiation therapy. It is often necessary to replace hormones that are lacking, even after successful treatment of a pituitary tumor.

    Hormone therapy is needed to replace hormones that are no longer made by organs under the control of the pituitary gland. These may include:

    • Corticosteroids (cortisol)
    • Growth hormone
    • Sex hormones (testosterone for men and estrogen for women)
    • Thyroid hormone

    Drugs are also available to treat related infertility in men and women.

    Expectations (prognosis)

    Hypopituitarism is usually permanent and requires lifelong treatment. However, you can expect a normal life span.


    Side effects of drug therapy can develop. In severe illness, failing to take extra corticosteroids can be life-threatening.

    Calling your health care provider

    Call your health care provider if you develop symptoms of hypopituitarism.
