does hyperkalemia cause acidosis
The form of renal tubular acidosis associated with hyperkalemia is usually attributable to real or apparent hypoaldosteronism. It is therefore a common feature in diabetes and a number of other conditions associated with underproduction of renin or aldosterone. In addition, the close relationship between potassium levels and ammonia production dictates that hyperkalemia per se can lead to acidosis.
The roles of aldosterone and hyperkalemia in the physiology of human hyperkalemic acidosis were considered in a case report in the New England Journal of Medicine. The case concerned a patient with hyperkalemic hypoaldosteronism but only moderate renal impairment.
