Symptoms typically occur during or after eating, including uncomfortable fullness after eating (early satiety) and bothersome epigastric burning or pain, without evidence of structural disease (i.e. normal upper endoscopy) to explain the symptoms. Dyspepsia has been classified into two subgroups by the Rome IV group: (1) postprandial distress syndrome; and (2) epigastric pain syndrome. It is estimated that as much as 25% of the world’s population suffers from dyspepsia. ![](https://s3.us-west-2.amazonaws.com/aboutirritablebowelsyndromecom-images/outbreaks/image9.jpeg)Recent studies have also demonstrated that, like post-infectious IBS, gastrointestinal infection may also act as a trigger for symptoms of functional dyspepsia (FD). In one study of individuals who had suffered *Salmonella* infection, 1 in 7 had symptoms of dyspepsia and 1 in 10 had symptoms of IBS. In another, more comprehensive study, physicians following thousands of individuals infected by *E. coli* O157:H7 in a drinking water outbreak found that FD was twice as common in those who had suffered gastrointestinal infection than in those who had not. Risk factors for FD were female sex, smoking, pre-existing IBS, anxiety, depression, and having an acute gastrointestinal illness longer than 7 days. A meta-analysis found the mean prevalence of FD after acute gastroenteritis was 9.55% in adults. Pathogens associated with FD included *Salmonella,* Shiga-toxin producing *E. coli O157:H7;* *Campylobacter jejuni, Giardia lamblia,* and *Norovirus.* ### Gastroparesis Gastroparesis is a condition in which stomach emptying is delayed, resulting in symptoms of nausea, vomiting, early satiety, and weight loss. It is most commonly associated with diabetes, but sporadic cases can occur. There appears to be a relationship with viral gastroenteritis, as studies have shown development after rotavirus infection in children. There are no studies linking gastroparesis to bacterial infection, but a link may exist. ![](https://s3.us-west-2.amazonaws.com/aboutirritablebowelsyndromecom-images/outbreaks/image10_2021-03-03-195848.jpeg?1615505001765) [ Next: IBS Diagnosis › ](https://marlerclark.com/foodborne-illnesses/irritable-bowel-syndrome/ibs-diagnosis) ### More Information [August 13, 2026 ###### Cyclospora and the 2026 Taylor Farms Outbreak: Questions and Answers Marler Clark represents people sickened in the 2026 Cyclospora outbreak and has filed cases naming Taylor Farms entities as defendants.
