Overt bleeding is further categorized into hematemesis (vomiting blood, red or coffee-ground), melena (black, tarry stools indicating altered blood and prolonged GI tract presence), and hematochezia (passage of red or maroon blood from the rectum, generally suggesting a lower GI source but occasionally an upper GI source in unstable patients). Occult bleeding, in the absence of overt signs, may manifest as symptoms of blood loss, iron deficiency anemia, or a positive fecal occult blood test. The document highlights acute upper GIB as a common gastrointestinal emergency in the UK, with a significant mortality rate. Peptic ulceration accounts for 30-50% of cases, and varices for 5-10%, necessitating distinct management strategies. Etiologies of Upper GIB discussed include gastric cancer and aorto-enteric fistula. The text emphasizes the importance of distinguishing between upper and lower GI sources due to differing management protocols.",{"@graph":14,"@context":55},[15,34],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/gastrointestinal-bleeding/26569/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/gastrointestinal-bleeding/26569.png","ImageObject",300,407,{"name":42,"@type":43},"Ezra","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-18","2026-05-08",true,{"@type":52,"interactionType":53,"userInteractionCount":22},"InteractionCounter",{"@type":54},"ViewAction","https://schema.org",{"og:url":57,"og:type":58,"og:title":10,"og:site_name":45,"og:description":12},"https://docshare.wps.com/document/gastrointestinal-bleeding/26569","article",{"robots":60,"canonical":57},"index,follow",{"doc_id":62,"site_id":7},26569,1778198879,{"code":4,"msg":65,"data":66},"success",[67,71,75,79,84,89,93,98,103,106,110],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":68,"show_sort_weight":69,"slug":70},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":72,"show_sort_weight":73,"slug":74},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":76,"show_sort_weight":77,"slug":78},"Exam",70,"exam",{"id":80,"doc_module":4,"doc_module_name":25,"category_name":81,"show_sort_weight":82,"slug":83},5,"Comic",60,"comic",{"id":85,"doc_module":4,"doc_module_name":25,"category_name":86,"show_sort_weight":87,"slug":88},6,"Technology",50,"technology",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":91,"slug":92},7,40,"healthcare",{"id":94,"doc_module":4,"doc_module_name":25,"category_name":95,"show_sort_weight":96,"slug":97},8,"Research & Report",30,"research-report",{"id":99,"doc_module":4,"doc_module_name":25,"category_name":100,"show_sort_weight":101,"slug":102},9,"Religion & Spirituality",20,"religion-spirituality",{"id":101,"doc_module":4,"doc_module_name":25,"category_name":104,"show_sort_weight":101,"slug":105},"World Cup","world-cup",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":108,"show_sort_weight":107,"slug":109},10,"Lifestyle","lifestyle",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":80,"slug":113},19,"General","general",{"code":4,"msg":65,"data":115},{"doc_id":62,"user_id":116,"nickname":42,"user_avatar":117,"doc_module":4,"category_id":90,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":11,"file_id":118,"file_url":119,"file_type":120,"file_size":121,"view_count":22,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":122,"language":123,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":11,"faqs":11,"seo_title":124,"seo_description":12,"update_tm":63,"read_time":125},1099514068035,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","cbCaipFskSi6xab1","https://ap.wps.com/l/cbCaipFskSi6xab1","pdf",3520708,29,"English","Gastrointestinal bleeding | PDF",73]
