Beer potomania is a condition caused by excessive consumption of beer which can result in low serum sodium levels, called hyponatremia. Given what you have learned about ion concentration, what would cause the low serum sodium levels?
a. The beer binds the sodium ions on the blood and they are eliminated in the urine.
b. The consumption of beer results in dehydration, and this reduces sodium ion concentration.
c. Over-hydration from beer consumption causes the blood serum to be diluted, resulting in low solute concentration.
d. Beer increases the permeability of the cell membranes allowing sodium to cross and resulting in serum concentrations being depleted.
c. Over-hydration from beer consumption causes the blood serum to be diluted, resulting in low solute concentration.
