This document provides information on Addison's disease, including its causes, signs and symptoms, diagnostic tests, treatment, and nursing care. Addison's disease is a condition where the adrenal glands do not produce enough cortisol and aldosterone hormones. It can develop from autoimmune disease, infections, surgery, or other reasons. Left untreated, it can cause low blood pressure, high potassium, and even an adrenal crisis. Treatment involves replacing the missing hormones with medications like hydrocortisone and fludrocortisone. Nurses monitor patients and provide education on managing the condition.
