2 DEFINITION:   According to the Rome III criteria, dyspepsia is defined as one or more of the following symptoms : ●Postprandial fullness (classified as postprandial distress syndrome) ●Early satiation (inability to finish a normal sized meal, also classified as postprandial distress syndrome) ●Epigastric pain or burning (classified as epigastric pain syndrome)

3 ETIOLOGY: It occurs in approximately 25 percent of the population each year 25 percent of patients with dyspepsia have an underlying organic cause 75 percent of patients have functional (idiopathic or nonulcer) dyspepsia with no underlying cause on diagnostic evaluation(These criteria should be fulfilled for the last three months with symptom onset at least six months before diagnosis.)

4 Dyspepsia secondary to organic disease
 Although there are several organic causes for dyspepsia, the main causes are: peptic ulcer disease gastroesophageal reflux, gastroesophageal malignancy nonsteroidal anti-inflammatory drug (NSAID)-induced dyspepsia

6 INITIAL EVALUATION: History:
A history, physical examination, and laboratory evaluation are the first steps in the evaluation of a patient with new onset of dyspepsia. History: ●A dominant history of heartburn, regurgitation, or cough is suggestive of GERD. ●NSAID use raises the possibility of NSAID dyspepsia and peptic ulcer disease. Radiation of the pain to the back or personal or family history of pancreatitis may be indicative of underlying chronic pancreatitis. ●Significant weight loss, anorexia, vomiting, dysphagia, odynophagia, and a family history of gastrointestinal cancers suggest the presence of an underlying malignancy. ●The presence of severe episodic epigastric or right upper quadrant abdominal pain lasting more than an hour or pain that occurs at any time is suggestive of symptomatic cholelithiasis.

7 Physical examination:
The physical examination in patients with dyspepsia is usually normal, except for epigastric tenderness. The presence of epigastric tenderness cannot accurately distinguish organic dyspepsia from functional dyspepsia. Abdominal tenderness on palpation should be evaluated with the Carnett sign to determine if it is due to pain arising from the abdominal wall rather than due to inflammation of the underlying viscera. Other informative findings on physical examination may include: a palpable abdominal mass (eg, hepatoma) or lymphadenopathy (eg, left supraclavicular or periumbilical in gastric cancer), jaundice (eg, secondary to liver metastasis) or pallor secondary to anemia. Ascites may indicate the presence of peritoneal carcinomatosis. Patients may have evidence of muscle wasting, loss of subcutaneous fat, and peripheral edema due to weight loss.

8 Laboratory tests:   Routine blood counts and blood chemistry including liver function tests should be performed to identify patients with alarm features (eg, iron deficiency anemia) and underlying metabolic diseases that can cause dyspepsia (eg, diabetes, hypercalcemia)

9 DIAGNOSTIC STRATEGIES AND INITIAL MANAGEMENT :
 The approach to and extent of diagnostic evaluation of a patient with dyspepsia is based on the presence or absence of alarm features ,patient age, and the local prevalence of Helicobacter pylori (H. pylori) infection . Patients with gastroesophageal reflux disease (GERD) and nonsteroidal anti-inflammatory drug (NSAID)-induced dyspepsia should be treated with an empiric trial of proton pump inhibitors (PPI) for eight weeks and NSAIDs should be discontinued. Further evaluation should be pursued if these patients continue to have symptoms after eight weeks of PPI therapy or earlier if they have alarm features

12 Test and treat for Helicobacter pylori
The rationale for H. pylori testing in patients with dyspepsia is based upon the recognition of H. pylori as an etiologic factor in peptic ulcer disease. Testing for H. pylori should be performed with a urea breath test or stool antigen assay. Serologic testing should not be used due to their low positive predictive value

13 Antisecretory therapy
Empiric antisecretory therapy without H. pylori testing/treatment should be recommended in areas of low prevalence for H. pylori (<10percent) Proton pump inhibitor therapy is more effective in relieving symptoms of dyspepsia as compared with H2 antagonists

14 EVALUATION OF PERSISTENT SYMPTOMS:
Patients with continued symptoms of dyspepsia should be carefully reassessed, paying specific attention to the type of ongoing symptoms, the degree to which symptoms have improved or worsened, and compliance with medications. Patients with continued symptoms of dyspepsia fall into the following categories: patients with persistent H. pylori infection, patients with an alternate diagnosis, and patients with functional dyspepsia.

15 An upper endoscopy should be performed in patients with persistent dyspepsia .Upper endoscopy allows for testing for H. pylori with biopsies for histology in patients who have not previously been tested and culture and sensitivity testing in patients who have previously been treated. Biopsies of the duodenum should also be performed to rule out celiac disease. In patients with a normal upper endoscopy, further evaluation should be performed based on the type of ongoing symptoms .An ultrasound of the gallbladder should be performed only in patients with pain suggestive of biliary disease .

16 Delayed gastric emptying :A gastric emptying study for gastroparesis should be considered in patients with persistent nausea and vomiting and in patients with risk factors for delayed gastric emptying (eg, diabetes mellitus). Diarrhea, constipation, bloating, and flatulence may be associated with inflammatory bowel disease (colonoscopy and small bowel radiography ). A diagnosis of chronic intestinal ischemia should be considered in patients with severe peripheral vascular disease or coronary artery disease (CT/MR angiography).
