It occurs as a result of erosions on the gastric mucosa secondary to traction at the hiatus during respiration and\/or gastric acid-related injuries to the mucosa. Even though anaemia occurs as a result of chronic gastrointestinal blood loss, testing for faecal occult blood is often negative and upper gastrointestinal endoscopy normal as the bleeding is intermittent. In children, a hiatus hernia as a rare cause of iron deficiency anaemia and has been described only in case reports. Here, we describe a 5-year-old boy who presented with severe transfusion-dependent iron deficiency anaemia caused by a paraoesophageal hernia. Surgical repair of the hiatus hernia led to complete resolution of anaemia. One should consider a hiatus hernia as a diagnostic possibility when evaluating a child with refractory iron deficiency anaemia.<\/jats:p>","DOI":"10.1136\/bcr-2020-237728","type":"journal-article","created":{"date-parts":[[2021,3,5]],"date-time":"2021-03-05T13:31:15Z","timestamp":1614951075000},"page":"e237728","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Unusual cause of severe iron deficiency anaemia in a child: paraoesophageal hernia"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1505-9761","authenticated-orcid":false,"given":"Rishi","family":"Bolia","sequence":"first","affiliation":[{"name":"Pediatric Gastroenterology, AIIMS Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yash","family":"Srivastava","sequence":"additional","affiliation":[{"name":"Pediatrics, AIIMS Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renu","family":"Yadav","sequence":"additional","affiliation":[{"name":"Pediatric Gastroenterology, AIIMS Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Poonam","family":"Sherwani","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, AIIMS Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,4]]},"reference":[{"key":"2025082801113059000_14.3.e237728.1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2036.2004.01894.x"},{"key":"2025082801113059000_14.3.e237728.2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2014\/479240","article-title":"Transfusion-Dependent anaemia: an overlooked complication of paraoesophageal hernias","volume":"2014","author":"Skipworth","year":"2014","journal-title":"Int Sch Res Notices"},{"key":"2025082801113059000_14.3.e237728.3","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1016\/j.pedneo.2016.05.008","article-title":"Hiatal hernia: a rare cause of iron-deficiency anemia in children","volume":"58","author":"Shih","year":"2017","journal-title":"Pediatr Neonatol"},{"key":"2025082801113059000_14.3.e237728.4","first-page":"76","article-title":"Paraesophageal hernia as a cause of chronic asymptomatic anemia in a 6 years old boy; case report and review of the literature","volume":"60","author":"Patoulias","year":"2017","journal-title":"Acta Medica"},{"key":"2025082801113059000_14.3.e237728.5","first-page":"66","article-title":"A baby with hiatal hernia presenting with severe iron-deficiency anemia","volume":"54","author":"\u00d6zdemir","year":"2019","journal-title":"Turk Pediatri Ars"},{"key":"2025082801113059000_14.3.e237728.6","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2001.118253"},{"key":"2025082801113059000_14.3.e237728.7","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1080\/20469047.2018.1489649","article-title":"Gastroesophageal reflux disease (GERD) in children","volume":"39","author":"Poddar","year":"2019","journal-title":"Paediatr Int Child Health"},{"key":"2025082801113059000_14.3.e237728.8","doi-asserted-by":"crossref","first-page":"22","DOI":"10.4103\/0189-6725.129206","article-title":"Peptic oesophageal stricture in children: management problems","volume":"11","author":"Zouari","year":"2014","journal-title":"Afr J Paediatr Surg"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-237728","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:11:36Z","timestamp":1756368696000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-237728"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":8,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,3,4]]},"published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1136\/bcr-2020-237728"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-237728","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
