[Rapid Resolution of Symptomatic Hypercalcaemia]

Rapid Resolution of Symptomatic Hypercalcaemia Abstract. Milk-alkali syndrome consists of the triad of hypercalcaemia, metabolic alkalosis, and renal insufficiency associated with the ingestion of calcium and absorbable alkali. Older patients, those at risk for volume depletion and those on medications that reduce glomerular filtration rate are at increased risk for the development of this syndrome. Most affected patients are postmenopausal women with chronic kidney disease who take an excessive amount of calcium carbonate. The incidence of milk-alkali syndrome is increasing due to the common supplementation of calcium carbonate. Nowadays, it is the third most common cause of hypercalcaemia. As shown in this case, hypercalcaemia may occur even with small amounts of calcium carbonate in patients with the given risk factors.
