Alcoholics get a moderate amount of their calories via beer consumption and do not experience this endogenous protein breakdown or its resultant low urea/solute level. With low solute intake, dramatically lower fluid intake (about 14 cans of beer) will overwhelm the kidneys’ ability to clear excess free water in the body. 2 Fortunately, most heavy beer drinkers continue to eat at least modestly, which is sufficient to avoid this rare type of hyponatremia. Chronic alcoholics who go on a drinking binge beyond their normal baseline alcohol consumption, or who develop a flulike illness that causes electrolyte depletion (via diarrhea or vomiting), are at higher risk for beer potomania.
