“…In order to produce 1 liter of maximally dilute urine, the kidneys require 50 mOsmol of solutes. This solute load is produced by urea generated from protein breakdown (10 g of protein produces around 50 mOsm of urea) [4]. Dietary sodium and potassium make up the remaining portion of the solute load.…”

“…A person with normal renal function and normal dietary intake removes about 600-900 mOsm/day. With the maximal urinary dilation of 50 mOsm/L, a person can excrete about 20 L of water without becoming hyponatremic, allowing for broad range of water intake (reaching up to 20 L) [ 5 - 7 ]. As free-water clearance in a person with normal diluting capacity is dependent on osmole excretion, a decrease in daily dietary osmole intake can have a vast decrease in the excretory capacity of the kidney.…”

“…In our two cases, patients with nine to 20, 12 oz cans of beer daily, their approximate osmole intake was 225-250 mOsm/L per day. Assuming normal urinary dilation capability, any fluid intake more than 3-4 L will result in water retention and subsequently dilutional hyponatremia in these patients [ 4 - 5 ]. In beer potomania patients, the ability to reabsorb free-water from the collecting tubules is decreased due to suppressed antidiuretic hormone [ 2 ].…”

“…The extreme manifestation of this is the rare condition of beer potomania, in which alcoholics who drink large amounts of fluid that is low in electrolytes, and have minimal protein intake, develop hyponatremia despite a normal urinary diluting ability [3,4,5,6,7,8,9,10,11,12]. This has also been described in patients on extreme weight-reducing diets that are very low in protein and high in water intake (e.g.…”
