Gastric bypass surgery as a cause of fat soluble vitamin deficiency is generally under-reported. Copper deficiency has been reported after gastric bypass surgery. Vitamin A deficiency after gastric bypass surgery has also been reported in the literature, but the reported cases again fall below the actual figures. B<jats:sub>12<\/jats:sub> and folate deficiencies can produce a type of myelopathy similar to that produced by copper deficiency, and differentiation on the basis of laboratory tests, neurophysiology and improvement of symptoms after replacement therapy might be the hallmark of diagnosis. Combinations of vitamin deficiencies were previously reported, but no cases of combined vitamin A and copper deficiency could be found in the literature.<\/jats:p>","DOI":"10.1136\/bcr-2013-202478","type":"journal-article","created":{"date-parts":[[2014,4,29]],"date-time":"2014-04-29T07:26:46Z","timestamp":1398756406000},"page":"bcr2013202478","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Night blindness due to vitamin A deficiency associated with copper deficiency myelopathy secondary to bowel bypass surgery"],"prefix":"10.1136","volume":"2014","author":[{"given":"Ali","family":"Abdul Jabbar AlHassany","sequence":"first","affiliation":[{"name":"Department of Neuroscience, East Kent Hospitals NHS Foundation Trust, Canterbury, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,4,29]]},"reference":[{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.1","doi-asserted-by":"crossref","first-page":"760695","DOI":"10.1155\/2011\/760695","article-title":"Clinical study: vitamin A deficiency after gastric bypass surgery: an underreported postoperative complication","volume":"2011","author":"Zalesin","year":"2011","journal-title":"J Obes"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.2","doi-asserted-by":"publisher","DOI":"10.1177\/0148607106030005446"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.3","doi-asserted-by":"publisher","DOI":"10.1097\/SMJ.0b013e3181b62614"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.4","doi-asserted-by":"crossref","first-page":"1196","DOI":"10.1177\/000313480607201209","article-title":"Incidence of vitamin deficiency after laparoscopic Roux-en-Y gastric bypass in a university hospital setting","volume":"72","author":"Clements","year":"2006","journal-title":"Am Surg"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.5","doi-asserted-by":"publisher","DOI":"10.1381\/096089299765553395"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.6","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000132644.52613.FA"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.7","doi-asserted-by":"publisher","DOI":"10.4065\/81.10.1371"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.8","first-page":"e330","article-title":"Reversible myelopathy with vitamin B12 deficiency","volume":"49","author":"Senol","year":"2008","journal-title":"Singapore Med J"},{"key":"2025082801261745000_2014.apr29_1.bcr2013202478.9","first-page":"339","article-title":"Myelopathy and macrocytic anemia associated with a folate deficiency.
