Five had presented with steatorrhoea of various causes while six had post-gastrectomy osteomalacia. Post-absorption levels of 25-OHD were low in four of the patients with steatorrhoea but normal in five of those with post-gastrectomy osteomalacia. There was a significant inverse correlation between peak post-absorption 25-OHD levels and faecal fat excretion. All patients with active post-gastrectomy osteomalacia had subnormal baseline plasma 25-OHD levels, which indicates that the condition is due to a deficiency of vitamin D. Only two of the patients with osteomalacia had estimated dietary vitamin D intakes ofer 1-75 microng\/day. These findings suggest that an oral 25-OHD absorption test may be a valuable measure of small intestinal function and that poor dietary vitamin D intake rather than impaired absorption of the vitamin may be the major cause of post-gastrectomy osteomalacia.<\/jats:p>","DOI":"10.1136\/bmj.1.6072.1310","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T18:32:30Z","timestamp":1238697150000},"page":"1310-1312","source":"Crossref","is-referenced-by-count":40,"title":["25-Hydroxycholecalciferol absorption in steatorrhoea and postgastrectomy osteomalacia."],"prefix":"10.1136","volume":"1","author":[{"given":"J M","family":"Gertner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Lilburn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Domenech","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1977,5,21]]},"container-title":["BMJ"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/data.bmj.org\/tdm\/10.1136\/bmj.1.6072.1310","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bmj.1.6072.1310","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,19]],"date-time":"2025-11-19T20:26:19Z","timestamp":1763583979000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bmj.com\/lookup\/doi\/10.1136\/bmj.1.6072.1310"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1977,5,21]]},"references-count":0,"journal-issue":{"issue":"6072","published-online":{"date-parts":[[1977,5,21]]},"published-print":{"date-parts":[[1977,5,21]]}},"alternative-id":["10.1136\/bmj.1.6072.1310"],"URL":"https:\/\/doi.org\/10.1136\/bmj.1.6072.1310","relation":{},"ISSN":["0007-1447","1468-5833"],"issn-type":[{"value":"0007-1447","type":"print"},{"value":"1468-5833","type":"electronic"}],"subject":[],"published":{"date-parts":[[1977,5,21]]}}}
