==Classification==
[[Dyspepsia]] is broadly classified into two major types:
* Ulcer dyspepsia: accounts to 20-30 % of all dyspepsia cases and is caused by [[Peptic ulcer disease]], [[GERD]]. Structural disease of the gastrointestinal tract exists in ulcer dyspepsia and hence endoscopy is abnormal.
* Non-ulcer dyspepsia: also called Functional dyspepsia. Functional dyspepsia (FD) is defined by the Rome III criteria as symptoms of epigastric pain or discomfort (prevalence in FD of 89-90%), postprandial fullness (75-88%), and early satiety (50-82%) within the last 3 months with symptom onset at least 6 months earlier. Patients cannot have any evidence of structural disease to explain symptoms and predominant symptoms of gastroesophageal reflux are exclusionary.<ref>{{cite journal |author=Lacy BE, Talley NJ, Locke GR, ''et al.'' |title=Review article: current treatment options and management of functional dyspepsia |journal=Aliment.

**Gastric motor function
**Visceral sensitivity
**Helicobacter pylori infection
**Psychosocial factors
