	Polydipsia (The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter) - WrongDiagnosis.com
		Polydipsia is a symptom that can be attributed to medical or psychogenic causes and has a prevalence of 3% to 39% among chronic psychiatric inpatients (1).
		Polydipsia usually starts abruptly in central DI and patients often have a preference for ice cold water (3).
		Patients with mild polydipsia are placed on fluid restriction starting at midnight prior to testing, but fluids are restricted in those with severe polydipsia during the day only.

		It is often, and characteristically, found in (Someone who has diabetes) diabetics, often as one of the initial symptoms, and in those who fail to take their anti-diabetic medications or whose dosages have become inadequate.

	Polydipsia and Polyuria - PetPlace.com
		The term polydipsia refers to excessive thirst manifested by excessive water intake, which in turn usually leads to polyuria, which is the formation and excretion of a large volume of urine.
		One of the first steps in the evaluation of a dog with polyuria and polydipsia is to determine the urine concentration by a test called “urine specific gravity.” The specific gravity of pure water is 1.000.
		The occurrence of polyuria and polydipsia usually does not constitute an emergency, but several potentially serious diseases (such as diabetes mellitus, kidney failure, liver failure or high blood calcium caused by a malignancy) may be the underlying cause of the symptoms.

		Finally, polydipsia has been found to be associated with high doses of neuroleptics as well as with moderate doses of anticholinergic medications (OR=1.8 and 1.9, CI =1.02-3.1 and 1.2-3.2).

		The causes of polyuria and polydipsia generally are related because the body tries to maintain a normal fluid volume.
		Polyuria and polydipsia themselves rarely cause serious problems for the pet, if free access to water is provided and the animal is willing and able to drink.
		Same cases of primary polydipsia are treated by restricting water intake; however, water restriction should be done only with directions from the veterinarian.

		The perceived increase in water intake or urine output may be a physiological response to alterations in the environment temperature, dietary changes (from moist to dry food or visa versa), or unrecognized water deprivation.
		Polydipsia may manifest itself as drinking from sources other than the water bowl, such as from toilets.

		Psychogenic polydipsia is an uncommon clinical disorder characterized by excessive water-drinking in the absence of a physiologic stimulus to drink.
		The diagnosis of psychogenic polydipsia is one of exclusion and requires specialist investigation and management; the most important test is the water deprivation test which should be undertaken carefully.
		Note that chronic psychogenic polydipsia may actually impair the response of the kidneys to ADH, and therefore reduce the renal concentrating ability.

	Polydipsia and Polyuria (Site not responding. Last check: 2007-11-03)
		Although diabetes mellitus is widely recognized as the commonest cause of polyuria and polydipsia, the possibility of diabetes insipidus (DI) is too often overlooked by physicians.
		It is very important to bear DI in mind because missing the diagnosis can lead to needless suffering by patients and their families; indeed, failure to make the diagnosis can result in severe dehydration with irreversible brain damage, even death.
		Forms of DI The term Diabetes Insipidus refers to an abnormal state of water diuresis (as opposed to an abnormal state of osmotic diuresis, as in diabetes mellitus); DI is characterized by a large volume of dilute urine (hypotonic polyuria) associated with increased fluid intake (polydipsia).

		Even if the estimated prevalence of polydipsia of between 6 and 17% in psychiatric inpatients is an over estimate, it is a common enough, and a serious enough condition to merit considerable clinical concern.

		It is presumed that a central defect in thirst regulation plays an important role in the pathogenesis of polydipsia [1,4].
		As an example, schizophrenic patients who are polydipsic are much more likely to be unable to normally suppress cortisol release after the administration of dexamethasone than those without polydipsia (38 versus 5 percent in one study) [8].

	Dear Dr Bandelow,
		During this episode of polydipsia, the patient presented headache, weakness, and diarrhoea.
		All the symptoms of polydipsia regressed after a brief period of strict fluid restriction, an anxiety-relieving treatment by slow intravenous administration of benzodiazepines and supportive psychotherapy.
		Thus, we concluded that the clinical signs of headache, weakness, and diarrhoea presented by this patient during the episode of polydipsia were not related to water sub-intoxication as we first thought.

	Daughter experiencing periods of extreme thirst.
		Your daughter has a symptom called polydipsia, in which there is extreme thirst with consumption of large amounts of water.
		Excessive thirst and water consumption- polydipsia and excess urine production- polyuria, are also the primary symptoms in nephrogenic diabetes insipidus, but the amount of urine produced is much less than in pituitary diabetes insipidus.
		Prolonged psycholgenic polydipsia can disrupt the normal kidney response to ADH as well as temporarily decreasing the release of ADH, and it may take several weeks for the kidneys to return to normal with restriction of fluid intake.

	Word! Polydipsia
		If someone's diabetes isn't under control, he or she might be really thirsty and drink a lot of fluids.
		In diabetes, polydipsia happens because the person's blood sugar levels are high and the kidneys are working overtime to get rid of the sugar.
		To do this, the kidneys produce more urine (pee).

		She does not have a diabetic history and she did not develop this condition until after she became symptomatic for depression.
		There is also a correlation between excessive water drinking (polydipsia) and psychosis--though this is usually seen in the context of schizophrenia.
		There is no strong evidence of an adrenaline surge in ordinary depression, but changes in the brain's neurochemical make up during either depression or psychosis (or psychotic depression) may be partly responsible for this unusual drinking behavior.

		The polydipsia had been present for several months before the owner noticed the lymphadenopathy.
		However, cushingoid signs remained (polydipsia, alopecia and muscle weakness) and the prednisolone dose was reduced significantly.
		In this case the urea concentration is probably low as a result of polydipsia (and ‘medullary washout’) — however, low urea concentrations are often seen in dogs with cushings disease and it has been suggested that this is a result of anabolic effects of the disease.

		These distinctions are usually easy when the deficiency of AVP is so severe that the patient is unable to concentrate his or her urine during a dehydration test.
		In this case, primary polydipsia is excluded and determining the change in urine concentration after injecting the AVP analogue, DDAVP, will usually distinguish pituitary from nephrogenic DI.
		However, if the dehydration test results in concentration of the urine, the distinction is more difficult because the patient can have either primary polydipsia or a partial defect in AVP secretion or action and the subsequent response to a conventional diagnostic dose of DDAVP does not differentiate between them.
