See also diabetes insipidus-central Alternative Names: Nephrogenic diabetes insipidus; Acquired nephrogenic diabetes insipidus; Causes, incidence, and risk factors: Antidiuretic hormone ADH vasopressin ) is a hormone produced in the hypothalamus of the brain. It concentrates the urine by triggering the kidneys to reabsorb water into the blood stream rather than excreting water into the urine. 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. Excessive amounts of water are excreted with the urine, producing a large quantity of very dilute urine. There is little or no response to vasopressin, even though the blood level of this hormone is higher than normal.

Main Search Index Definition Description Causes ... Resources Diabetes insipidus Definition Diabetes insipidus (DI) is a disorder that causes the patient to produce tremendous quantities of urine. The massively increased urine output is usually accompanied by intense thirst. Description The balance of fluid within the body is maintained through a number of mechanisms. One important chemical involved in fluid balance is called antidiuretic hormone (ADH). ADH is produced by the pituitary, a small gland located at the base of the brain. In a healthy person, and under normal conditions, ADH is continuously released. ADH influences the amount of fluid that the kidneys reabsorb into the circulatory system and the amount of fluid that the kidneys pass out of the body in the form of urine. Production of ADH is regulated by the osmolality of the circulating blood. Osmolality refers to the concentration of dissolved chemicals (such as sodium, potassium, and chloride; together called solute) circulating in the fluid base of the blood (plasma). When there is very little fluid compared to the concentration of solute, the pituitary will increase ADH production. This tells the kidneys to retain more water and to decrease the amount of urine produced. As fluid is retained, the concentration of solute will normalize. At other times, when the fluid content of the blood is high in comparison to the concentration of solute, ADH production will decrease. The kidneys are then free to pass an increased amount of fluid out of the body in the urine. Again, this will allow the plasma osmolality to return to normal.

© Diabetes UK 2000 Diabetes Insipidus 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. The inability to retain water is usually due to a shortage of a hormone called antidiuretic hormone (ADH, sometimes called vasopressin), which is made by the pituitary gland situated underneath the brain. Occasionally normal amounts of ADH are present, but the kidneys are not able to use it properly. Diabetes Insipidus is much less common than Diabetes Mellitus. In many cases there is no obvious cause for the inability of the pituitary gland to make ADH. In other people an inflammation, infection around the pituitary gland or a head injury may lead to the loss of ADH secretion. Operations on the pituitary gland may also lead to Diabetes Insipidus, but as in the case of a head injury, this is often temporary. Doctors diagnose Diabetes Insipidus by taking blood and urine samples from patients who have not had anything to drink for several hours. In most people this would lead to the passing of small amounts of concentrated urine, but patients with Diabetes Insipidus continue to pass large amounts of dilute urine. Special x-rays of the pituitary gland may also be performed.

A Case of Diabetes Insipidus by David F. Dean Department of Biology Spring Hill College Case Presentation Amanda Richards is a 20-year-old junior in college. She is majoring in biology and hopes someday to be a pediatrician. Beginning about a month ago, Amanda noticed that she was waking up once, sometimes twice a night, by the need to go to the bathroom. More recently, she has noticed that she needs to go to the bathroom during her school day much more frequently than before, sometimes as often as once every hour. At first Amanda thought that her increased frequency of urination was due to the coffee she drank, but when she reduced her coffee consumption to one cup in the morning, she still needed to go to the bathroom just as often. In addition, Amanda was buying bottled water by the case, and she found herself never without a beverage in her hand or nearby. She also noticed that her urine seemed pale and colorless. Next, a two-hour water deprivation test was performed on Amanda. After two hours of not being able to drink water, the osmolarity of her plasma and urine were measured a second time. This time her urine osmolarity was unchanged; however, the osmolarity of her plasma increased to 315 mOsm/L. She was then injected with a drug called DDAVP . One hour after the injection, the osmolarity of her plasma decreased to 290 mOsm/L and the osmolarity of her urine increased to 425 mOsm/L.

A chronic metabolic disorder characterized by intense thirst and excessive urination, caused by a deficiency of the pituitary hormone vasopressin. [New Latin diabētēs īnsipidus : Latin diabētēs , diabetes + Latin īnsipidus , insipid.] Diagnosis Diabetes Insipidus What is diabetes insipidus? Diabetes insipidus (DI) is an endocrine disorder involving deficient production or lack of effective action of an antidiuretic hormone (ADH or vasopressin). ADH is made in the hypothalamus (lower part of the brain), stored in and secreted by the pituitary gland (a small gland located below the hypothalamus), and works on the kidney to conserve fluid. Deficient production of ADH or lack of effective action of ADH causes large amount of urine output, increasing thirst, dehydration, and low blood pressure in advanced cases. Average urine volume for a normal adult is 1.5 liters daily. In diabetes insipidus, the urine volume can approach 18 liters daily! Diseases of the hypothalamus/pituitary gland causing lack of ADH production is called central DI. Diseases of the kidney causing lack of response of the kidney to fluid conserving action of ADH is called nephrogenic DI.

This condition sometimes occurs in people with insulin-dependent diabetes and (rarely) in people with noninsulin-dependent diabetes. Unlike the Somogyi effect, it is not a result of an insulin reaction. People who have high levels of blood glucose in the mornings before eating may need to monitor their blood glucose during the night. If blood glucose levels are rising, adjustments in evening snacks or insulin dosages may be recommended.

Diabetes insipidus (DI) results from abnormalities in the production or use (two main types) of the hormone arginine vasopressin. The main symptoms are excessive thirst and massive urination. The excess urine flow is devoid of sugar. There are no blood glucose abnormalities, and in fact there is nothing in common with diabetes mellitus except the excess urination when untreated. Diabetes insipidus caused by failure to produce vasopressin. This is known as neurogenic DI (or central DI, or pituitary DI). It can be treated with hormone replacement (by nasal spray or other routes). DI caused by failure to use vasopressin (nephrogenic DI) is more difficult to treat, but several drugs are available which help. DI is much less common than diabetes mellitus, though a few people have discussed it on misc.health.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. American Diabetes Association Diabetes CookBook What Is Diabetes Type One Diabetes Type Two Diabetes ... Weight Loss Secrets
