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.
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 ...
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.
In primary polydipsia, the urine osmolality should increase and stabilize at above 280 mOsm/kg with fluid restriction, while a stabilization at a lower level indicates diabetes insipidus. [18] Stabilization in this test means, more specifically, when the increase in urine osmolality is less than 30 Osm/kg per hour for at least three hours. [ 18 ]
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.
Dementia impacts almost 10% of older adults in the U.S. While scientists haven’t pinpointed exactly what causes it, research is slowly identifying new factors, like diet, that may play a role in ...
Continuous dehydration can cause acute and chronic diseases, but is most often associated with renal and neurological disorders. [1] Excessive thirst, called polydipsia, along with excessive urination, known as polyuria, may be an indication of diabetes mellitus or diabetes insipidus.
