GERD and PUD are among the most common GI diagnoses — and among the most commonly overtreated. The key clinical skill is recognizing alarm features that demand endoscopy before empiric acid suppression. PPIs are effective, but they are not a substitute for diagnosis.
CLINICAL PRINTABLE
Coming Soon.
A one-page GERD / Peptic Ulcer Disease clinical reference is on the way.
1 · Recognition / Alarm Features
- GERD: heartburn, regurgitation, chest discomfort, chronic cough, laryngitis, or dental erosion — symptoms worse after meals, lying down, or with certain foods.
- PUD: epigastric pain, often postprandial (gastric ulcer) or relieved by food (duodenal ulcer), nausea, early satiety, or GI bleeding.
- Alarm features requiring urgent endoscopy: dysphagia, odynophagia, unintentional weight loss, GI bleeding (hematemesis, melena, hematochezia), iron deficiency anemia, persistent vomiting, palpable abdominal mass, age >60 with new symptoms.
- Test for H. pylori in all patients with PUD — H. pylori is present in approximately 70–80% of duodenal ulcers and 50–60% of gastric ulcers.
2 · Treatment Pathway
Lifestyle modifications
Elevate head of bed, avoid late meals, reduce alcohol/caffeine/fatty foods, lose weight if overweight, avoid NSAIDs. Lifestyle alone is rarely sufficient for moderate-severe GERD but is an important adjunct.
PPI therapy
PPIs are the most effective acid suppression for GERD and PUD. Take 30–60 minutes before the first meal of the day for maximum efficacy. Use the lowest effective dose for the shortest necessary duration.
H. pylori eradication
Test and treat H. pylori in all PUD patients. Confirm eradication with urea breath test or stool antigen at least 4 weeks after completing therapy and 2 weeks after stopping PPI.
H2 receptor antagonists
H2RAs are less potent than PPIs but appropriate for mild-intermittent GERD, nocturnal acid breakthrough, or as step-down therapy.
NSAID-induced PUD
Stop the NSAID when possible. If NSAID must continue, use the lowest effective dose with a PPI. Consider COX-2 selective agents in high-risk patients.
3 · Expected Response
- GERD symptoms typically improve within 1–2 weeks of PPI therapy; complete healing of erosive esophagitis takes 4–8 weeks.
- PUD healing with PPI therapy: duodenal ulcers typically heal in 4–6 weeks; gastric ulcers in 8–12 weeks.
- H. pylori eradication reduces ulcer recurrence from >80% to <5% at 1 year — confirm eradication.
- Failure to respond to PPI therapy should prompt reassessment: is the diagnosis correct? Is the PPI being taken correctly? Is there a complication?
4 · Escalation
- GI bleeding from PUD: IV PPI, endoscopy for hemostasis, resuscitation. High-dose IV PPI infusion after endoscopic hemostasis reduces rebleeding.
- Perforated peptic ulcer: acute abdomen, free air on imaging — emergency surgical consultation.
- Barrett's esophagus: metaplastic change in esophageal mucosa from chronic GERD — endoscopic surveillance per guidelines.
- GI/surgery referral for refractory GERD, Barrett's esophagus, complicated PUD, or alarm features.
Apply It · Change One Detail
APPLY IT
A 45-year-old with 3 months of heartburn and regurgitation, no alarm features, no prior endoscopy. Empiric PPI trial for 4–8 weeks is appropriate. If symptoms resolve and recur on stopping, consider maintenance therapy or further evaluation.
CHANGE ONE DETAIL
Change one detail — the same patient has dysphagia and 10 lb weight loss over 2 months. Empiric PPI is not the next step. Urgent upper endoscopy is required to exclude malignancy.
Bottom Line
Alarm features in GERD or dyspepsia demand endoscopy before empiric acid suppression — do not treat your way past a cancer.
