Stomach Ulcers and GERD: The Real Link, Symptoms, and Treatment

You feel burning in your chest, maybe a gnawing ache under the ribs, and you’re wondering: is this reflux, an ulcer, or both? People mix these up all the time. They’re different conditions, but they collide in real life-symptoms overlap, the same meds get used, and one problem can hide the other. Here’s the plain-English version of how they connect, how to tell them apart, when to get tested, and what to do next without wasting months guessing.

• GERD and ulcers are not the same: GERD is acid washing up into your oesophagus; ulcers are sores in the stomach or duodenum, usually from H. pylori or NSAIDs.
• They can coexist: ulcer pain can mimic heartburn, and scarring from ulcers can worsen reflux. PPIs help both, but you shouldn’t stay on them forever without a plan.
• Think H. pylori if you have upper stomach pain, nausea, or use anti-inflammatory painkillers. Test before long-term PPIs, and confirm eradication after antibiotics.
• Red flags need urgent care: trouble swallowing, vomiting blood, black stools, fainting, persistent vomiting, anemia, or weight loss.
• Smart first steps: pause NSAIDs if possible, start a short PPI trial for classic reflux, elevate the bedhead, and talk to your GP about testing.

What connects GERD and ulcers (and what doesn’t)

Here’s the blunt truth: GERD does not usually cause stomach ulcers. Ulcers mainly come from an infection (H. pylori) or from regularly using nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen. Acid is the accomplice, not the mastermind. GERD, on the other hand, is about weak pressure at the lower oesophageal sphincter and other factors letting acid (and sometimes bile) flow back up.

Where’s the link then? First, symptoms overlap. A burning behind the breastbone screams reflux, but a deep, gnawing ache high in the abdomen-especially if it comes and goes with meals-leans ulcer. The catch: either can cause upper abdominal burning, nausea, early fullness, and even chest pain. Second, one problem can amplify the other. Ulcer scarring near the pylorus (the stomach’s outlet) can slow emptying, which increases back-pressure and reflux. NSAIDs can both cause ulcers and aggravate reflux. Finally, PPIs (acid-suppressing meds) treat both, which helps-but also muddies the water if you never test for H. pylori.

What about H. pylori and reflux? In some people, long-standing H. pylori reduces acid production, which can blunt reflux symptoms. After eradication, acid output may rise slightly and uncover reflux that was already poised to happen. Most modern guidelines don’t see this as a reason to skip treatment. If you have H. pylori, treating it is the right move because it prevents ulcers and bleeding (ACG GERD guideline 2022; RACGP H. pylori guidance 2022; NICE Dyspepsia guideline 2019).

So the practical link is this: separate conditions, overlapping symptoms, shared treatments-with H. pylori and NSAIDs sitting at the center of the ulcer story, not GERD. Getting the sequence right-test, treat, then reassess-is what stops the cycle.

Note on Australia: urea breath testing and stool antigen testing for H. pylori are widely available; PPIs are PBS-subsidised when prescribed. Local GPs typically use a “test-and-treat” strategy for uninvestigated dyspepsia without alarm features.

What to do next: self-checks, tests, and treatments

If you’re trying to figure out your next move, use this simple decision path. It won’t replace your GP, but it stops the guesswork.

1. Spot the dominant pattern

   • More heartburn and sour regurgitation, worse when lying down? Think GERD first.
   • More upper stomach ache/gnawing, nausea, or pain that tracks with meals? Think ulcer/dyspepsia and H. pylori testing.
   • Using NSAIDs or aspirin regularly? Assume higher ulcer risk until you’re tested.

2. Check for red flags (urgent care if any)

   • Difficulty or pain with swallowing, food sticking
   • Vomiting blood or coffee-ground material
   • Black or maroon stools, fainting, severe anemia
   • Unintentional weight loss, persistent vomiting
   • Severe chest pain with sweating/shortness of breath (call emergency-heart first)

3. Testing strategy

   • Classic GERD (heartburn/regurgitation) without red flags: reasonable to do a 2-4 week PPI trial.
   • Dyspepsia or ulcer-sounding pain, or you’re an NSAID/aspirin user: test for H. pylori before committing to long-term PPIs.
   • If you’re 50+ with new-onset upper gut symptoms, have significant weight loss, or anemia, your GP may prioritise endoscopy per local guidance.

4. How to prepare for H. pylori testing

   • Stop PPIs for 2 weeks before urea breath or stool antigen tests.
   • Avoid antibiotics and bismuth for 4 weeks before testing.
   • Confirm eradication 4+ weeks after finishing antibiotics (and off PPI for 2 weeks).

5. Treatment moves

   • GERD: PPI once daily 30 minutes before breakfast for 4-8 weeks; add an alginate at bedtime for regurgitation; elevate the bedhead 10-20 cm; target weight loss if overweight; avoid late, large, fatty meals.
   • Ulcer/H. pylori: your GP will prescribe a 14-day regimen (often quadruple therapy) based on local resistance; always confirm eradication; continue a PPI for healing as advised.
   • NSAID-related risk: if possible, stop NSAIDs; if you must use them, your doctor may consider a COX-2 selective agent plus PPI; weigh risks if you’re also on low-dose aspirin or blood thinners.

Heuristics that save time and trouble:

• If your main symptom is regurgitation, alginates are underrated-they form a raft on top of stomach contents and reduce splash-back.
• Night-time symptoms? Sleep on your left side and raise the bedhead; both reduce nocturnal reflux episodes.
• Not all “triggers” matter equally. Weight loss and bed elevation have the strongest evidence. Coffee, chocolate, and spicy food are personal-test, don’t guess.
• Don’t stop PPIs cold turkey. Taper over 2-4 weeks to avoid rebound acid: alternate-day dosing for a week or two, then step down to H2 blockers as needed.
• Smokers heal ulcers slower and reflux more-quitting helps both conditions.

Pitfalls to avoid:

• Masking H. pylori with indefinite PPI use. Treating the infection prevents future ulcers and bleeding.
• Using NSAIDs to dull ulcer pain. That’s petrol on the fire.
• Assuming chest pain is reflux. If it’s exertional or comes with breathlessness or sweating, get cardiac causes ruled out first.
• Repeating the same antibiotic bundle for H. pylori after it fails once. Your GP may switch to a different regimen based on resistance patterns.

Evidence notes, minus the alphabet soup: ACG (2022) supports PPI trials for typical GERD and emphasises endoscopy for alarm features. RACGP and NICE endorse test-and-treat for H. pylori in uninvestigated dyspepsia under an age threshold and without alarms. Meta-analyses show global H. pylori prevalence around the 40% mark and strong reductions in ulcer recurrence after eradication. PPI therapy controls typical reflux in most patients, especially alongside weight loss and bed elevation.

Cheat-sheets, scenarios, and FAQ

Spot-the-difference checklist (use this when your symptoms blur together):

• Heartburn/regurgitation dominant, worse after big or late meals, or when lying flat → more likely GERD.
• Gnawing epigastric pain, nausea, pain tied to meals, relief with antacids/food → more likely ulcer/dyspepsia.
• Regular NSAIDs/aspirin use, prior ulcer, or positive H. pylori test → higher ulcer probability.
• Nocturnal cough, hoarseness, sour taste in mouth → reflux pointers.
• Melena (black stools), vomiting blood, or sudden severe pain → emergency until proven otherwise.

Doctor discussion cheat-sheet (bring this to your GP):

• My main symptoms are: [heartburn/regurgitation] or [upper stomach pain/nausea].
• Medications I take: [NSAIDs/aspirin/blood thinners], [PPIs/H2 blockers], [others].
• I’d like H. pylori testing before long-term PPIs if dyspepsia dominates.
• Plan if positive: treatment and test-of-cure. If negative: GERD-focused plan.
• Any reason I need endoscopy now? (age, alarms, anemia, weight loss, long-standing reflux)

Common scenarios and what to do:

• Regular NSAID user (e.g., for knee pain): ask if you can switch pain strategies; consider COX-2 selective plus PPI; test for H. pylori before stopping PPI long-term.
• On a PPI but still symptomatic: check timing (take 30 minutes before breakfast); add an alginate at bedtime; consider twice-daily dosing short term with your GP; assess for H. pylori and for non-acid reflux or functional heartburn if symptoms don’t fit.
• After H. pylori treatment, reflux flares: that can happen; optimise lifestyle, run a short PPI course, and confirm eradication before assuming treatment failed.
• Night-time reflux: left-side sleeping, bedhead elevation, lighter evening meals, alginate at bedtime, and avoid alcohol late.
• Pregnancy: start with lifestyle measures, antacids, and alginates; PPIs have reassuring safety data but still discuss with your obstetrician.
• On blood thinners or low-dose aspirin: never stop them without medical advice; your GP will balance clotting risk vs ulcer risk and may add gastroprotection.

Mini-FAQ:

• Can GERD cause ulcers? Not typically. Ulcers are chiefly from H. pylori or NSAIDs. GERD irritates the oesophagus, not the stomach lining where most peptic ulcers form.
• Can an ulcer feel like heartburn? Yes. Ulcers can cause burning in the upper abdomen that’s easy to mistake for reflux. That’s why testing matters.
• Does H. pylori make reflux better or worse? It can dampen acid in some people, so eradicating it may unmask reflux. Treat it anyway; it prevents ulcers and bleeding. Any reflux uptick is usually manageable.
• Do spicy foods cause ulcers? No. They may sting an existing ulcer or irritate reflux, but they don’t cause ulcers.
• Is stress the cause? Stress doesn’t directly cause ulcers, but it can nudge habits (smoking, NSAIDs) and pain perception. Critical illness is a separate scenario with true stress ulcers.
• How long can I stay on a PPI? Use the lowest effective dose, and try to step down once symptoms are controlled and H. pylori is addressed. Long-term use is fine when clearly indicated (e.g., severe oesophagitis), monitored by your doctor.
• When do I need an endoscopy? Alarm features, persistent symptoms despite good therapy, recurrent vomiting, bleeding/anemia, unintended weight loss, or if your doctor worries about complications or alternative diagnoses.

Next steps and troubleshooting by persona:

• If you’re under 50 with classic heartburn/regurgitation, no red flags: 2-4 week PPI trial + lifestyle changes; reassess. If better, plan a taper and on-demand strategy.
• If you have dyspepsia dominant symptoms or take NSAIDs: request H. pylori testing before long-term PPIs; if positive, treat and confirm cure; if negative, treat symptomatically and reassess.
• If you’re 50+ with new upper gut symptoms, or you have anemia/weight loss: see your GP soon to discuss endoscopy rather than a long blind trial.
• If you need daily NSAIDs or aspirin: talk gastroprotection-PPI co-therapy, H. pylori test, and whether a COX-2 selective is safer for you.
• If symptoms persist despite correct PPI use: double-check timing, try alginate add-on, consider twice-daily dosing short term with your GP, and evaluate for non-acid reflux, motility issues, or functional disorders.

Why trust this? The approach above mirrors major guidelines: ACG 2022 for GERD management and when to scope; RACGP and NICE for H. pylori test-and-treat and dyspepsia; and large meta-analyses showing the global footprint of H. pylori and ulcer prevention after eradication. Ask your local GP to tailor it to your meds, age, and risk factors.
