Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
The thiazides and potassium-sparing diuretics are considered to be calcium-sparing diuretics. [6] The thiazides cause a net decrease in calcium lost in urine. [7] The potassium-sparing diuretics cause a net increase in calcium lost in urine, but the increase is much smaller than the increase associated with other diuretic classes. [7]
Potassium-sparing diuretics act to prevent sodium reabsorption in the collecting tubule by either binding ENaCs (amiloride, triamterene) or by inhibiting aldosterone receptors (spironolactone, eplerenone). This prevents excessive excretion of K + in urine and decreased retention of water, preventing hypokalemia. [10]

Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
Potassium replacement becomes of utmost importance in this setting because potassium is usually lost in urine. If blood levels of potassium are depleted below normal levels, then hypokalemia occurs, which promotes bicarbonate ion retention and prevents bicarbonate excretion, thus interfering with alkalinization of the urine.
Thiazides combined with potassium citrate, increased water intake and decreased dietary oxalate and sodium can slow or even reverse the formation of calcium-containing kidney stones. [18] High-dose therapy with the thiazide-like diuretic indapamide can be used to treat idiopathic hypercalcinuria (high urine calcium with unknown cause). [19]
Abuse of diuretic medications (water pills): The physician must screen urine for multiple diuretics before a diagnosis is made. Magnesium deficiency and calcium deficiency: These patients will also have low serum and urine magnesium and calcium. Patients with Bartter syndrome may also have elevated renin and aldosterone levels. [10]
