Hypercalcaemia due to the milk-alkali syndrome
This case report is about an 87-year-old woman with Alzheimer’s disease and the milk-alkali syndrome, who took calcium carbonate as osteoporosis prophylaxis. We describe, how the milk-alkali syndrome can result in a triad of hypercalcaemia, metabolic alkalosis, and renal insufficiency. The syndrome is now the third most common cause of hypercalcaemia because of the use of calcium carbonate in osteoporosis prophylaxis and treatment, and the syndrome should be considered in patients with hypercalcaemia, as it may result in permanent renal impairment.
