Step-by-step explanation:
Adrenal insufficiency, also known as Addison's disease, is characterized by the reduced production of cortisol from the adrenal glands. This can be caused by malfunction of the adrenal glands or decreased availability of ACTH from the pituitary gland. Symptoms of Addison's disease include low blood pressure, paleness, extreme weakness, fatigue, slow movements, lightheadedness, salt cravings, loss of appetite, chronic diarrhea, vomiting, mouth lesions, and patchy skin color. Diagnosis involves blood tests and imaging tests, and treatment typically includes cortisol replacement therapy.
