Study Notes
Hyposecretion (Addison's Disease)
- Damage to the pituitary gland can lead to reduced ACTH production, causing Addison's disease.
Hypersecretion (Cushing's Syndrome)
- Tumors in the adrenal glands can cause excessive cortisol production, even with normal ACTH levels, leading to Cushing's syndrome symptoms.
Diagnosis
- ACTH measurement blood tests determine if ACTH is elevated (indicating Cushing's syndrome) or suppressed (indicating Addison's disease).
Causes of Pituitary Gland Damage
- Stroke or head injury can damage the blood vessels or tissues of the pituitary gland.
- In rare cases, an infection can damage the pituitary gland.
Treatment
- Surgery, such as thyroidectomy (removal of part or all of the thyroid), may be necessary in severe cases.
