Cases in which the urine is dilute include adrenal insufficiency, hypothyroidism, and drinking too much water or too much beer. [4] Cases in which the urine is concentrated include syndrome of inappropriate antidiuretic hormone secretion (SIADH). [4] High volume hyponatremia can occur from heart failure, liver failure, and kidney failure. [4]
40% of all hospitalized adults aged 65 and older have hyponatremia, with an estimated 25–40% of those cases being due to inappropriate antidiuresis. [2] The incidence of SIADH rises with increasing age with residents of nursing homes being at highest risk. [20]
More severe hyponatremia (levels less than 120 mEq/L), particularly if it develops rapidly (defined as occurring over less than 48 hours), can cause confusion, seizures and even lead to death ...
[14] [3] Dilutional hyponatremia can happen in diabetics as high glucose levels pull water into the blood stream causing the sodium concentration to be lower. [14] [3] Diagnosis of the cause of hyponatremia relies on three factors: volume status, plasma osmolality, urine sodium levels and urine osmolality. [14] [3]
The low GFR causes a lowered rate of osmole excretion, and an increase in the amount of water reabsorbed; thus, hyponatremia occurs when the amount of water intake exceeds the renal water excretion capacity. [2] Medications, such as thiazides and antidepressants, may exacerbate symptoms of hyponatremia. [2]

The common advice to drink 8 glasses (1,900 mL or 64 US fl oz) of plain water per day is not scientific; thirst is a better guide for how much water to drink than is a specific, fixed amount. [4] Americans aged 21 and older, on average, drink 1,043 mL (36.7 imp fl oz; 35.3 US fl oz) of drinking water a day, and 95% drink less than 2,958 mL (104 ...
The fractional excretion of sodium (FE Na) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium , rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption .
