Adrenal Gland Hormones - Cushing's Disease Explained

The pituitary gland regulates adrenal gland hormone release via negative feedback. The adrenal glands release aldosterone, cortisol, and testosterone to help us deal with stress.  Aldosterone increases kidney retention of salt and water and therefore can increase blood pressure.  Cortisol mobilizes fat stores and increases blood glucose by stimulating lipolysis and gluconeogenesis.  Testosterone prepares the mind and body for physical conflict.  Too much of these hormones results in Cushing's Disease, and a lack of them results in Addison's Disease.
