Dyspepsia
1. Definition
Dyspepsia = Chronic or recurrent pain or discomfort centered in the upper abdomen (epigastrium).
It includes one or more of:
- Epigastric pain
- Epigastric burning
- Early satiety
- Postprandial fullness
- Bloating
- Nausea
Heartburn alone = GORD, not dyspepsia (though overlap is common).

2. Pathophysiology
Dyspepsia may be:
A. Organic (structural cause)
- Peptic ulcer disease
- Malignancy
- Pancreatic disease
- Biliary disease
- Drug-induced
B. Functional (most common)
Functional Dyspepsia (FD)
Defined by Rome IV Criteria
Requires:
- ≥1 symptom:
- Postprandial fullness
- Early satiety
- Epigastric pain
- Epigastric burning
- No structural disease on endoscopy
- Symptoms ≥3 months, onset ≥6 months before diagnosis
Subtypes:
- Postprandial distress syndrome (PDS)
- Epigastric pain syndrome (EPS)

3. Causes of Dyspepsia
— Gastric Causes
- Peptic Ulcer Disease
- Gastritis
- Gastric carcinoma
- Lymphoma
— Infection
- Helicobacter pylori
— Drug-Induced
- NSAIDs
- Steroids
- Bisphosphonates
- Iron
- Metformin
— Reflux Disease
- Gastroesophageal Reflux Disease
— Pancreatic
- Chronic pancreatitis
- Pancreatic carcinoma
— Biliary
- Gallstones
- Biliary colic
— Malignancy Red Flags
- Gastric cancer
- Pancreatic cancer
4.Alarm Features
Immediate endoscopy if:
- Age ≥55 (UK NICE cutoff; may vary regionally)
- Unintentional weight loss
- Dysphagia
- Persistent vomiting
- GI bleeding
- Iron deficiency anemia
- Epigastric mass
- Family history of upper GI cancer
5. Clinical Assessment
History
Ask about:
- Relation to meals
- NSAID use
- Weight loss
- Vomiting
- Dysphagia
- Alcohol
- Smoking

6. Investigation Strateg
Stepwise Approach (NICE-based)
# Age <55, No Alarm Features
➡ Test and treat for H. pylori
Tests:
- Urea breath test (best)
- Stool antigen
- Serology (not preferred)
# Age ≥55 OR Alarm Features
➡ Urgent OGD (endoscopy)

7. Management
A. Lifestyle
- Weight reduction
- Stop smoking
- Reduce alcohol
- Avoid NSAIDs
- Small frequent meals
- Avoid trigger foods
B. H. pylori Eradication
Triple therapy (14 days):
- PPI
- Amoxicillin
- Clarithromycin
OR metronidazole if penicillin allergy
Confirm eradication after 4 weeks.
C. Acid Suppression
First line:PPI for 4–8 weeks
If relapse:
- Long-term lowest effective dose
D. Functional Dyspepsia Management
- PPI trial
- H. pylori eradication if positive
- Prokinetics (limited use)
- Low-dose TCA (e.g., amitriptyline)
- Psychological therapy if refractory
8. Complications of Untreated Organic Dyspepsia
- GI bleeding
- Perforation
- Gastric outlet obstruction
- Malignancy progression
9. Specia Scenarios
# NSAID User
Stop NSAID + PPI
Test for H. pylori
# Elderly New-Onset Dyspepsia
Always scope
# Persistent Symptoms After PPI
- Check compliance
- Test H. pylori
- Consider functional dyspepsia
- Consider biliary or pancreatic cause
