Primary polydipsia may have physiological causes, such as autoimmune hepatitis. Since primary polydipsia is a diagnosis of exclusion, the diagnosis may be made for patients who have medically unexplained excessive thirst, and this is sometimes incorrectly referred to as psychogenic rather than primary polydipsia.
In the absence of diabetes mellitus, the most common causes are the decreased secretion of aldosterone due to adrenal cortical tumor, primary polydipsia (excessive fluid drinking), central diabetes insipidus, and nephrogenic diabetes insipidus. [6] Polyuria may also be due to various chemical substances, such as diuretics, caffeine, and ethanol.
Zinc is also known to reduce symptoms of polydipsia by causing the body to absorb fluids more efficiently (reduction of diarrhea, induces constipation) and it causes the body to retain more sodium; thus a zinc deficiency can be a possible cause. The combination of polydipsia and (nocturnal) polyuria is also seen in (primary) hyperaldosteronism ...
The most obvious cause is a kidney or systemic disorder, including amyloidosis, [2] polycystic kidney disease, [3] electrolyte imbalance, [4] [5] or some other kidney defect. [2] The major causes of acquired nephrogenic diabetes insipidus that produce clinical symptoms (e.g., polyuria) in the adult are lithium toxicity and high blood calcium.
Dipsogenic DI or primary polydipsia results from excessive intake of fluids as opposed to deficiency of arginine vasopressin. It may be due to a defect or damage to the thirst mechanism, located in the hypothalamus, [11] or due to mental illness. Treatment with desmopressin may lead to water intoxication. [12]
When this happens, it’s known as essential hypertension or primary hypertension. High blood pressure can be caused by a combination of lifestyle factors like: Having overweight or obesity
Polyuria (excessive urine production) of which, in turn, the most frequent causes are: uncontrolled diabetes mellitus, primary polydipsia (excessive fluid drinking), central diabetes insipidus and nephrogenic diabetes insipidus. [20] Polyuria generally causes urinary urgency and frequency, but does not necessarily lead to incontinence.
It differentiates primary polydipsia from diabetes insipidus and central diabetes insipidus from nephrogenic diabetes insipidus. Diabetes insipidus is treated by restoring free water deficit, replacing the missing hormone, and addressing the underlying ailment. Desmopressin, an arginine vasopressin analog, is used to treat central diabetes ...
