Question: can drinking too much alcohol cause hyponatremia?
Answer: Electrolyte abnormalities are common findings in patients with a history of heavy alcohol use. Excessive consumption of beer in particular, which has a low solute content (sodium concentration, 1.8 mEq/L and potassium concentration, 7.2 mEq/L), to the exclusion of other solute intake may result in severe hyponatremia.
