side by side comparison
GERD vs Peptic Ulcer Disease: Acid in the Wrong Place — Esophagus vs Stomach/Duodenum
All three conditions involve acid destroying tissue, but the pain patterns are mirror images of each other. Pick the wrong pain-meal relationship on the NCLEX and you'll select the wrong teaching, wrong medication timing, and wrong complication to monitor.

Dimension
GERD
Gastric Ulcer
Duodenal Ulcer
Pathophysiology & risk
- Reflux past incompetent LES
- Lower esophageal mucosa injured
- Mucosal erosion, stomach body/antrum
- H. pylori present in ~70%
- Erosion in duodenal bulb past pylorus
- H. pylori present in ~90%
Signs & symptoms
- ★Substernal burning (heartburn)
- Regurgitation
- Symptoms worse lying flat
- Epigastric gnawing pain
- ★Pain WITH eating, 30 min–1 hr after
- ★Pain BETWEEN meals, 2–4 hr after
- Night pain
- Epigastric gnawing pain
- Food or antacids relieve pain
Diagnostics & labs
- 24-hr esophageal pH monitoring
- EGD to screen for Barrett
- EGD + biopsy to rule out malignancy
- H. pylori: urea breath or stool antigen
- H. pylori: urea breath or stool antigen
Nursing priorities
- Elevate HOB 30°
- Stay upright after meals
- No food 2–3 hr before bed
- Monitor for GI bleed
- Stop NSAIDs/aspirin
- Monitor for GI bleed
- Stop NSAIDs/aspirin
Management
- PPI or H2 blocker
- PRN antacids
- No antibiotics needed
- PPI + triple therapy if H. pylori+
- Bismuth quadruple therapy (14 days)
- PPI + triple therapy if H. pylori+
- Bismuth quadruple therapy (14 days)
Patient teaching
- Limit alcohol
- Avoid caffeine, large/fatty meals
- Weight loss
- Avoid tight clothing
- Smoking cessation
- Limit alcohol
- Smoking cessation
- Limit alcohol
- Smoking cessation
- Regular meal schedule
Red flags — escalate
- Dysphagia or weight loss: needs EGD
- Hematemesis or melena: GI bleed
- Rigid, boardlike abdomen: perforation
- Hematemesis or melena: GI bleed
- Rigid, boardlike abdomen: perforation
Complications
- ★Barrett esophagus
- Esophageal adenocarcinoma risk
- Hemorrhage, perforation
- Higher malignancy risk — always biopsy
- Hemorrhage, perforation
- Gastric outlet obstruction from scarring

- TopicGERDThat persistent "heartburn" your patient ignores could be silently destroying esophageal tissue — and the nursing interventions that stop it have nothing to do with antacids alone.
- TopicPeptic Ulcer DiseaseA patient reports burning epigastric pain that worsens with eating versus one whose pain improves with food — that single distinction tells you which ulcer type you're dealing…
