In hyperkalemia, what happens to urinary output?

Explanation:
High potassium triggers aldosterone release, which acts on the distal nephron to increase sodium reabsorption and potassium secretion. As sodium is reabsorbed, water follows by osmosis, so less fluid reaches the bladder. That means urinary output tends to decrease in hyperkalemia. In cases of substantial kidney impairment, output can be low or very low, but the typical physiologic response with intact renal function is reduced urine volume.
