Introduction
A constellation of symptoms alone or in various combinations as outlined under clinical manifestations.
Etiology
- generally occursas a consequence of delayed gastric emptying time
- idiopathic (functional dyspepsia)
- mechanical obstruction
- inflammation & edema with secondary scarring
- tumors in pyloric region
- Crohn's disease involving the stomach or duodenum
- idiopathic hypertrophic pyloric stenosis
- non obstructive processes
- cholecystitis
- pancreatitis
- hepatitis
- appendicitis
- peritonitis
- gastroenteritis
- peptic ulcer disease
- sepsis
- uremia
- vagotomy
- metabolic disorders
- ketoacidosis
- psychosocial factors
- systemic lupus erythematosus
- scleroderma
- hyperplastic gastritis
- sarcoidosis
- neoplasm outside the GI tract
- congestive heart failure
- pulmonary tuberculosis
- paraplegia
- postsurgical immobilization
- electrolyte abnormalities
- diabetic neuropathy
- pharmaceuticals
- NSAIDs
- bisphophonates
- antibiotics
- potassium supplements
- other[2]
Epidemiology
- prevalence is 20-30%
- annual incidence of 1%
Clinical manifestations
- upper abdominal pain or discomfort
- postprandial fullness
- abdominal bloating
- belching
- early satiety
- anorexia
- nausea/vomiting
- pyrosis, epigastric burning (heartburn)
- 'red flags'
- anemia or occult gastrointestinal bleeding
- dysphagia
- weight loss
- new onset dyspepsia age > 55 years
- also see alarm features of dyspepsia
Laboratory
- testing for Helicobacter pylori[11]
Diagnostic procedures
- electrocardiogram prior to upper GI endoscopy (EGD) if acute dyspepsia
- esophagogastroduodenoscopy (EGD) is normal[2]
- testing for specific malabsorption syndromes if indicated
* ref[12] seems to discourage EGD in patients < 60 years even if 'red flags' present[12]
Radiology
- abdominal ultrasound
- computed tomography (CT)
- CT angiography if mesenteric ischemic suspected[2]
Complications
see alarm features of dyspepsia
Differential diagnosis
- functional dyspepsia
- idiopathic
- may occur concurrently with irritable bowel syndrome
- inflammation or infection
- peptic ulcer disease
- gastroesophageal reflux disease (GERD)
- gastric malignancy
- esophageal malignancy
- cholecystitis
- myocardial infarction
- pericarditis
- pancreatitis
- pleurisy
Management
- life-style modification
- tobacco cessation
- weight loss/food restriction
- avoidance of eating 2-3 hours before bedtime
- alcohol avoidance
- avoidance of aggravating foods
- elevating head of bed
- test for H pylori & treat if positive if < 60 years of age[2]
- EGD for elderly > 60 years of age[2]
- test & treat more cost effective[13]
- higher cost, higher patient satisfaction with EGD[13]
- prevalence of H pylori of only 17% suggests EGD may be appropriate regardless of age[14]
- EGD for elderly > 60 years of age[2]
- antacids
- H2-receptor antagonists
- cimetidine (Tagamet)
- ranitidine (Zantac)
- famotidine (Pepcid)
- nizatidine (Axid)
- roxatidine
- proton pump inhibitors (1st line)[2][11]
- omeprazole (Prilosec) superior to ranididine[3]
- lansoprazole no better than placebo[5]; effective[11] & NEJM
- low-dose tricyclic antidepressant if symptoms do not respond to once daily proton pump inhibitor[2]
- promotility agents
- metoclopramide (Reglan)
- delayed gastric emptying does not effect quality of life[4]
- mucosal coating agents - sucralfate
- specific therapies for specific etiologies
- acupuncture may be of benefit for post-prandial dyspepsia[15]
