    The Effects of Diuretics on Mineral and Bone Metabolism.
    Pediatr Endocrinol Rev 2018 Mar;15(4):291-297
    Division of Pediatric Nephrology, Children's Mercy Hospital Kansas City, 2401 Gillham Road, Kansas City, MO, USA, E-mail:
    The effects of diuretics on water and electrolyte metabolism are well-established, but less known to the clinician are their effects on bone and mineral metabolism, and in particular on that of calcium homeostasis. In general, and clinically most relevant, diuretics acting at the thick ascending limb of the loop of Henle cause loss of calcium into the urine, thus making them a useful tool in treating hypercalcemia. However the hypercalciuria caused by loop diuretics may lead to the development of urolithiasis and nephrocalcinosis, as well as secondary hyperparathyroidism and bone disease. Read More
