The two most common causes of hypercalcaemia, making up around 90% of the cases, are malignancy and primary hyperparathyroidism. Initial investigations are guided by this knowledge. In this case, no underlying malignancy or evidence of a parathyroid adenoma causing primary hyperparathyroidism was found. Instead, on further history, it was found that this patient had troublesome dyspepsia symptoms for which he had ingested 10\u201312 calcium carbonate tablets a day for the preceding 2\u2009years. This amounts to 6.6\u20137.9 g of calcium carbonate per day compared with the guideline daily intake of calcium of 1 g. His presentation of severe hypercalcaemia was therefore diagnosed as milk-alkali syndrome secondary to calcium carbonate tablet abuse.<\/jats:p>","DOI":"10.1136\/bcr-2017-219611","type":"journal-article","created":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T06:05:16Z","timestamp":1493877916000},"page":"bcr-2017-219611","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Antacid abuse: a rare cause of severe hypercalcaemia"],"prefix":"10.1136","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0261-9603","authenticated-orcid":false,"given":"Ben","family":"Stoney","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gautam","family":"Bagchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,5,3]]},"reference":[{"doi-asserted-by":"publisher","key":"2025042706023749000_2017.may03_1.bcr-2017-219611.1","DOI":"10.1136\/bmj.h2723"},{"doi-asserted-by":"crossref","unstructured":"Fern\u00e1ndez-Garc\u00eda M , V\u00e1zquez L , Hern\u00e1ndez JL .
