A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. [1] The amount of urine produced can be nearly 20 liters per day. [ 1 ] Reduction of fluid has little effect on the concentration of the urine. [ 1 ]
This is in contrast to central or neurogenic diabetes insipidus, which is caused by insufficient levels of vasopressin (also called antidiuretic hormone, ADH). Nephrogenic diabetes insipidus is caused by an improper response of the kidney to vasopressin, leading to a decrease in the ability of the kidney to concentrate the urine by removing ...
This means that psychogenic polydipsia may lead to test results (e.g. in a water restriction test) consistent with diabetes insipidus or SIADH, leading to misdiagnosis. [14] Dry mouth is often a side effect of medications used in the treatment of some mental disorders, rather than being caused by the underlying condition. [15]
Central diabetes insipidus, recently renamed arginine vasopressin deficiency (AVP-D), [1] is a form of diabetes insipidus that is due to a lack of vasopressin (ADH) production in the brain. Vasopressin acts to increase the volume of blood (intravascularly), and decrease the volume of urine produced.
The use in SIADH actually relies on a side effect; demeclocycline induces nephrogenic diabetes insipidus (dehydration due to the inability to concentrate urine). [ 10 ] [ 12 ] [ 13 ] The use of demeclocycline in SIADH was first reported in 1975, [ 14 ] and, in 1978, a larger study found it to be more effective and better tolerated than lithium ...
Syndrome of inappropriate antidiuretic hormone secretion (SIADH), also known as the syndrome of inappropriate antidiuresis (SIAD), [2] is characterized by a physiologically inappropriate release of antidiuretic hormone (ADH) either from the posterior pituitary gland, or an ectopic non-pituitary source, such as an ADH-secreting tumor in the lung. [1]
Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent feelings of thirst. [1] [2] It involves an increased osmolality or concentration of solute in the urine, which stimulates secretion of antidiuretic hormone (ADH) from the hypothalamus to the kidneys.
