A general term referring to disorders characterized by excessive urine excretion (polyuria).Diabetes Insipidus
A disease of the pituitary gland or kidney, not diabetes mellitus. Diabetes insipidus is often called "water diabetes" to set it apart from "sugar diabetes." The cause and treatment are not the same as for diabetes mellitus. "Water diabetes" has diabetes in its name because most people who have it show most of the same signs as someone with diabetes mellitus-they have to urinate often, get very thirsty and hungry, and feel weak. However, they do not have glucose (sugar) in their urine. It is a metabolic disorder due to injury of the neurohypophyseal system, which results in a deficient quantity of antidiuretic hormone being released or produces, and thus in failure of tubular reabsorption of water in the kidney. There is a passage of a large amount of urine of low specific gravity, and great thirst; it is often attended by voracious appetite, loss of strength, and emaciation. It may be inherited, acquired, or idiopathic.Diabetes Mellitus
A disease that occurs when the body is not able to use sugar as it should. The body needs sugar for growth and energy for daily activities. It gets sugar when it changes food into glucose (a form of sugar). A hormone called insulin is needed for the glucose to be taken up and used by the body. Diabetes occurs when the body cannot make use of the glucose in the blood for energy because either the pancreas is not able to make enough insulin or the insulin that is available is not effective. The beta cells in areas of the pancreas called the islets of Langerhans usually make insulin.
