Editing Gastroenteritis (section)

===Non-infectious===
There are a number of non-infectious causes of inflammation of the gastrointestinal tract.<ref name=EBMED2010/> Some of the more common include medications (like [[NSAIDs]]), certain foods such as [[lactose]] (in those who are intolerant), and [[gluten]] (in those with [[Coeliac disease|celiac disease]]). [[Crohn's disease]] is also a non-infectious cause of (often severe) gastroenteritis.<ref name=EBMED2010/> Disease secondary to [[toxin]]s may also occur. Some food-related conditions associated with nausea, vomiting, and diarrhea include: [[Ciguatera|ciguatera poisoning]] due to consumption of contaminated predatory fish, [[scombroid food poisoning|scombroid]] associated with the consumption of certain types of spoiled fish, [[Tetrodotoxin#Poisoning|tetrodotoxin poisoning]] from the consumption of [[puffer fish]] among others, and [[botulism]] typically due to improperly preserved food.<ref>{{cite journal|last=Lawrence|first=DT|author2=Dobmeier, SG |author3=Bechtel, LK |author4= Holstege, CP |title=Food poisoning|journal=Emergency Medicine Clinics of North America|date=May 2007 |volume=25|issue=2|pages=357–73; abstract ix|pmid=17482025|doi=10.1016/j.emc.2007.02.014}}</ref>

In the United States, rates of emergency department use for noninfectious gastroenteritis dropped 30% from 2006 until 2011. Of the twenty most common conditions seen in the emergency department, rates of noninfectious gastroenteritis had the largest decrease in visits in that time period.<ref>{{cite journal | vauthors = Skiner HG, Blanchard J, Elixhauser A | title = Trends in Emergency Department Visits, 2006–2011 | journal =HCUP Statistical Brief |issue=179 | publisher = Agency for Healthcare Research and Quality | location = Rockville, MD | date = September 2014 | url = https://www.hcup-us.ahrq.gov/reports/statbriefs/sb179-Emergency-Department-Trends.jsp | url-status=live | archive-url = https://web.archive.org/web/20141224224220/http://www.hcup-us.ahrq.gov/reports/statbriefs/sb179-Emergency-Department-Trends.jsp | archive-date = 2014-12-24 }}</ref>
