DRUGS
LUMINAL CAUSES
SYSTEMIC DISEASES
 No evidence of structural disease on endoscopy or
imaging or basic evaluation.
Functional Dyspepsia
 1. Epigastric pain
 2. Epigastric burning
 3. Early satiation
 4. Bothersome postprandial fullness
1 or more
Epigastric Pain Syndrome
 1. Pain or burning - epigastrium -moderate severity, 1/week
 2. Intermittent
 3. Not generalized or localized to other abdominal or chest
regions
 4. Not relieved by defecation or passage of flatus
 5. Not fulfilling criteria for gallbladder or sphincter of Oddi
disorders
all the above.
 Supportive Criteria
1. Pain may be of a burning quality but without a retrosternal
component
2. Pain is commonly induced or relieved by ingestion of a
meal but may occur while fasting
3. Postprandial distress syndrome may coexist
Postprandial Distress Syndrome
 1. Bothersome postprandial fullness, after ordinary sized
meals, at least several times/week
 2. Early satiation that prevents finishing regular meal, at least
several times/week
Supportive Criteria:
1. Upper abdominal bloating or nausea or belching
2. Epigastric pain syndrome may coexist
PATHOPHYSIOLOGY
 Hypersensitivity to gastric distention
 Delayed gastric emptying
 Impaired gastric accommodation to a meal
 Altered duodenal sensitivity to lipids or acid
 Abnormal intestinal motility
 Central nervous system dysfunction
GASTRIC EMPTYING
 Distal stomach-grinding and sieving until particles are small
enough to pass through pylorus
 Delayed gastric emptying ranges from 20% to 50%
 Solid gastric emptying- 30-40%
 Postprandial fullness, nausea and vomiting
IMPAIRED GASTRIC ACCOMMODATION
 Impaired in 40%
 Proximal stomach-reservoir during and after ingestion
of a meal.
 Relaxation- vagally mediated
 Rise in intragastric pressure
 Meal-induced satiation
 Activation of tension-sensitive mechanoreceptors
Hypersensitivity to Gastric Distension
 To isobaric gastric distention
 Tension-sensitive mechanoreceptors
 Altered visceral afferent nerves and the central
nervous system
Altered Duodenal Sensitivity to Lipids or Acid
 Gastric distention- cholecystokinin
 Duodenal hypersensitivity to acid
 Increased postprandial duodenal acid exposure-
impaired clearancE of acid
OTHERS
 Rapid gastric emptying
 Phasic fundic contractions
 Lack of suppression of phasic contractility of the proximal
stomach
 Duodenal retrograde contractions
 Genetic predisposition-G-protein beta polypeptide 3
 Hp Infection
 Postinfection Functional Dyspepsia-acute Salmonella
gastroenteritis
 Anxiety, depressive,somatoform disorders, physical or sexual
abuse
DIABETIC GASTROPARESIS
 Loss of ICCs
 Reduced receptive relaxation and accommodation
 Antral hypomotility.
 Isolated pyloric contractions-Pylorospasm.
 Gastric dysrhythmias-abnormal intragastric distribution of
food.
 Antral dilation
 Impaired action of prokinetic drugs.
 Modifies upper GI sensations
 Gastric smooth muscle dysfunction
General measures
 Lifestyle and dietary measures
 Eat smaller, more frequent meals
 Avoiding meals with a high fat
 Avoid spicy foods- capsaicin
 Avoid- coffee
 Cessation of smoking and consumption of alcohol
 Avoidance of aspirin and other NSAIDs
 Treat- coexisting anxiety disorder or depression
APPROACHES
 (1) Prompt diagnostic endoscopy followed by targeted
medical therapy
 (2) Noninvasive testing for Hp infection, followed by
treatment based on the result (“test-and-treat”
strategy)
 (3) Empirical anti-secretory drug therapy
Not Recommended= empirical therapy with a
prokinetic agent
Prompt Endoscopy and Directed Treatment
 Family history of gastric cancer
 High rate of gastric cancer country
 Had a partial gastrectomy
 Peptic ulcer, erosive esophagitis, or malignancy
 Reassures-patients and physicians
 Diagnosis of Hp infection- eradication therapy
 Functional dyspepsia and GERD recurs after
discontinuing PPI
Test and Treat for Hp Infection
 Hp- associated with peptic ulcers & gastric cancer
 Young patients- noninvasive testing
 Eliminates chronic gastritis
 The test and- treat strategy= Hp infection rate is high
Empirical Antisecretory Drug Therapy
 Beneficial in 1/3rd of functional dyspepsia
 Response usually within 2 weeks of therapy
 Economically- equally or more cost-effective than test
& treat strategy
Acid-Suppressive Drugs
 Both therapeutic and diagnostic value
 H2RAs & PPI are effective
 Half-dose=full-dose=double-dose PPI therapy
 Hp status did not affect the response
 Most effective for GERD also.
 Less effective- epigastric pain & dysmotility
Eradication of Hp Infection
 Induce sustained remission of dyspepsia
 Low number of responder
 Delayed symptomatic benefit
 Protects against- peptic ulcer, gastric cancer
 Short duration and low cost of treatment.
Prokinetic Agents
 Dopamine receptor agonists-upper GI motility
 5-hydroxytryptamine 4 (5-HT4) receptor agonism
 Motilin receptor agonist ABT-229
 Mixed 5-HT4 receptor agonist and 5-HT3 receptor
antagonist mosapride
 5-HT4 receptor agonist tegaserod
 Dopamine D2 antagonist/acetylcholinesterase inhibitor
itopride
Antidepressants
 Functional GI disorders not initially responding
 Anxiolytics and antidepressants-TCA
 The effect- independent of the presence of depression,
decrease visceral sensitivity
 SSRI- increased gastric accommodation
OTHERS
 M1 and M2 muscarinic receptor antagonist & inhibits
cholinesterase- Acotiamide
 Bismuth salts
 Simethicone
 5-HT1A, 5-HT3, 5-HT4- agonists-enhance gastric
accommodation
 Neurokinin receptor antagonists and peripherally kappa
opioid receptor agonists-Visceral hypersensitivity
 Alleviating postprandial fullness, early satiation and upper
abdominal bloating.
Psychological Interventions
 Group support with relaxation training
 Cognitive therapy
 Psychotherapy
 Hypnotherapy
