  Diabetes insipidus - Wikipedia, the free encyclopedia
Diabetes insipidus (DI) is a disease characterized by excretion of large amounts of severely diluted urine, which cannot be reduced when fluid intake is reduced.
Symptoms of diabetes insipidus are quite similar to those of severely deranged diabetes mellitus, with the distinction that the urine is not sweet and there is no hyperglycemia (elevated blood glucose).
Central diabetes insipidus is due to damage to the hypothalamus or pituitary due to a tumor, stroke, neurosurgery or some rather rare causes (which include hemochromatosis, sarcoidosis, histiocytosis and some genetic disorders).

 The Facts About Diabetes Insipidus
It is not possible to diagnose diabetes insipidus until the symptoms of excessive thirst and urination are present.
Diabetes insipidus is caused by the lack of antidiuretic hormone (vasopressin), and sugar diabetes is caused by lack of the hormone insulin.
If a child has diabetes insipidus and is in school, it is important for the teacher and school officials to be aware of this problem and the sometimes "immediate" need to drink water and go to the bathroom.

 Diabetes Insipidus
Diabetes insipidus is the excretion of a large volume of hypotonic, insipid (tasteless) urine, usually accompanied by excessive polydipsia.
Hypothalamic diabetes insipidus (or neurogenic DI) is the inability to secrete (and usually to synthesize) vasopressin in response to increased osmolality.
As in hypothalamic diabetes insipidus, the dilute filtrate entering the collecting duct is excreted as a large volume of hypotonic urine.

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.
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.

 Diabetes Insipidus: Encyclopedia of Medicine
Diabetes insipidus (DI) is a disorder that causes the patient to produce tremendous quantities of urine.
Diabetes insipidus occurs when either the amount of ADH produced by the pituitary is below normal (central DI), or the kidneys' ability to respond to ADH is defective (nephrogenic DI).
Uncomplicated diabetes insipidus is controllable with adequate intake of water and most patients can lead normal lives.

 Diabetes Insipidus
Diabetes insipidus is a metabolic disorder that causes the patient to produce enormous quantities of urine accompanied by excessive thirst.
Diabetes insipidus can occur after an injury to the head; brain surgery; cancer; sarcoidosis, causing destruction of the pituitary gland; the use of certain medications that decrease ADH production; excessive use of alcohol; and any condition or illness that causes decreased oxygen delivery to the brain.

 DIABETES INSIPIDUS
Diabetes insipidus can be caused either by a defect in the pituitary gland in the brain (central diabetes insipidus) or a defect in the kidney (nephrogenic diabetes insipidus).
In cases of nephrogenic diabetes insipidus, medications are used to reduce the volume of urine passed, while the levels of potassium in the blood must be monitored closely.

Diabetes insipidus is characterised by extreme thirst and the passing of vast amounts of urine.

Thus the name Diabetes Mellitus implies that patients with this condition lose large amounts of urine which is sweet and full of sugar, whereas in the case of Diabetes Insipidus the urine, although passed in excess, is tasteless and does not contain sugar.
Diabetes Insipidus is not related to Diabetes Mellitus except that patients with either condition are thirsty and pass a lot of urine.
In the case of Diabetes Insipidus increased amounts of urine are passed because the body cannot retain water; the body has normal amounts of sugar and insulin.

Nephrogenic diabetes insipidus is a disorder characterized by the passage of large volumes of urine due to a defect of the kidney tubules.
Nephrogenic diabetes insipidus involves a defect in the kidney tubules (the portion of the kidneys that causes water to be excreted or reabsorbed).
The specific kidney defect is usually a partial or complete failure of special receptors located on or within the kidney tubules to respond to ADH, the hormone that transmits the instruction to concentrate the urine to the inside of the cells.

 Central Diabetes Insipidus: Pituitary Gland Disorders: Merck Manual Home Edition
Another type of diabetes insipidus, nephrogenic diabetes insipidus, may be caused by abnormalities in the kidneys (see Tubular and Cystic Kidney Disorders: Nephrogenic Diabetes Insipidus).
The diagnosis of central diabetes insipidus is confirmed if, in response to antidiuretic hormone, the person's excessive urination stops, the urine becomes more concentrated, the blood pressure rises, and the heart beats more normally.
The diagnosis of nephrogenic diabetes insipidus is made if, after the injection, the excessive urination continues, the urine remains dilute, and blood pressure and heart rate do not change.

diabetes insipidus, central - A metabolic disorder due to injury of the neurohypophyseal system, which results in a deficient quantity of antidiuretic hormone being released or produced, and thus in failure of tubular reabsorption of water in the kidney.
diabetes insipidus, nephrogenic - A syndrome of polyuria and hyposthenuria caused by the failure of the renal tubules to reabsorb water in response to antidiuretic hormone, without disturbance in the renal filtration and solute excretion rates; the condition does not respond to exogenous vasopressin.
It may be inherited as a rare X-linked trait or be acquired as a result of drug therapy or systemic disease.

 Diabetes Insipidus - The Merck Veterinary Manual
The lesions responsible for the disruption of ADH synthesis or secretion in hypophyseal diabetes insipidus include large pituitary neoplasms (endocrinologically active or inactive), a dorsally expanding cyst or inflammatory granuloma, and traumatic injury to the skull with hemorrhage and glial proliferation in the neurohypophyseal system.
These include nephrogenic diabetes insipidus (an inability of the kidneys to respond to ADH), psychogenic diabetes insipidus (a polydipsia in response to some psychological disturbance but a normal response to ADH), and hypercortisolism (which results in a partial deficiency of ADH activity due to the antagonistic effect of cortisol on ADH activity in the kidneys).
The most common are diabetes mellitus with glycosuria and high urine specific gravity, and chronic nephritis with a urine specific gravity that is usually low and shows evidence of renal failure (protein, casts, etc).
