[2] Psychogenic polydipsia caused by psychiatric disorders—oftentimes schizophrenia —is frequently accompanied by the sensation of dry mouth. Some conditions with polydipsia as a ...
A confirmed diagnosis has seven elements: 1) a decreased effective serum osmolality - <275 mOsm/kg of water; 2) urinary sodium concentration high - over 40 mEq/L with adequate dietary salt intake; 3) no recent diuretic usage; 4) no signs of ECF volume depletion or excess; 5) no signs of decreased arterial blood volume - cirrhosis, nephrosis, or ...
Treatment. Depends on cause [5] (See cause) Polyuria (/ ˌpɒliˈjʊəriə /) is excessive or an abnormally large production or passage of urine (greater than 2.5 L [1] or 3 L [6] over 24 hours in adults).

hypocalcemia. Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance, oxygen delivery, acid–base balance and much more.
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 .
