Central Diabetes Insipidus (CDI) is a condition that affects the body's ability to regulate fluid levels. It is commonly referred to as Neurogenic Diabetes Insipidus, which emphasizes the condition's neurological origin rather than its underlying mechanism. Other synonyms for CDI include Vasopressin-Sensitive Diabetes Insipidus, which highlights the hormone vasopressin's role in the condition, and Pituitary Diabetes Insipidus, which specifically implicates the pituitary gland as the culprit. CDI is sometimes confused with another diabetes-related condition called Central Diabetes Mellitus, which occurs when the body is unable to properly process glucose. It is important to understand the distinctions between these disorders and seek proper medical attention if any symptoms occur.
