Can rich beers like ales raise potassium levels ?

YESSSSS!!!!: 'ol's raise potassium and sodium levels ! (alcohol, like mannit 'ol') (look up mannitol) are both osmotic diuretics-- they make you peeee. This type of diuretic (think 'water pill') can reek havoc on sodium and potassium, and worse cause an acidosis-- which is the headache result in hangovers. In an emergency (heart failure) doctors can rescue a patient by giving alcohol to a person with fluid in.
