Stomach Pain & Burning: Causes and Treatment

Understanding the Symptoms

⚠️ Red Flag Symptoms — See a Doctor Urgently

• Unintentional weight loss
• Difficulty swallowing (dysphagia)
• Vomiting blood or black/tarry stools
• Iron-deficiency anemia
• Persistent vomiting
• Age >55 with new-onset symptoms

Treatment Approach

1. Lifestyle Modifications (First-Line for All Causes)

• Avoid triggers: NSAIDs (ibuprofen, aspirin), alcohol, spicy foods, fatty meals, caffeine, carbonated drinks
• Smaller, more frequent meals — reduces gastric distension
• Don't lie down within 2–3 hours of eating
• Elevate the head of the bed (for nighttime reflux)
• Quit smoking — worsens acid production and mucosal defense
• Lose excess weight — reduces reflux pressure
• Reduce stress — linked to functional dyspepsia

2. Medications

Antacids (Fastest Relief)

• Examples: aluminum/magnesium hydroxide (Maalox, Mylanta), calcium carbonate (Tums)
• How they work: Neutralize gastric acid immediately
• Best for: Mild, occasional burning; quick symptom relief
• Limitation: Short-acting; not effective for functional dyspepsia

H2 Receptor Antagonists (H2 Blockers)

• Examples: famotidine (Pepcid), ranitidine (largely withdrawn), cimetidine
• How they work: Block histamine-driven acid secretion
• Best for: Mild-moderate GERD, peptic ulcers (healing support), nocturnal acid suppression
• Note: Only marginally effective for functional dyspepsia

Proton Pump Inhibitors (PPIs) — Most Effective Acid Suppressants

• Examples: omeprazole (Prilosec), pantoprazole (Protonix), esomeprazole (Nexium), lansoprazole (Prevacid)
• How they work: Irreversibly block the H⁺/K⁺-ATPase pump, reducing acid production by >90%
• Best for: GERD, erosive esophagitis, peptic ulcer disease, H. pylori regimens, NSAID-associated ulcers
• Use: Typically taken 30–60 minutes before the first meal of the day
• Duration: 4–8 weeks for ulcer healing; longer for GERD maintenance
• Note: Recent evidence confirms PPIs remain superior to H2 blockers for acid-related disorders. A 2024 network meta-analysis (PMID: 39412166) also supports vonoprazan (a newer potassium-competitive acid blocker) as effective for gastric/duodenal ulcer treatment and prevention (PMID: 39294424)

H. pylori Eradication (if H. pylori is present)

• Standard Triple Therapy (7–14 days):
  • PPI + clarithromycin + amoxicillin (or metronidazole)
• Bismuth Quadruple Therapy (preferred in areas of high clarithromycin resistance):
  • PPI + bismuth subcitrate + metronidazole + tetracycline

H. pylori eradication resolves peptic ulcers in most patients and reduces dyspeptic symptoms — Sleisenger and Fordtran's GI & Liver Disease

Prokinetics (for Functional Dyspepsia / Slow Gastric Emptying)

• Examples: metoclopramide, domperidone, acotiamide (Japan/India)
• Best for: Postprandial fullness, early satiation (postprandial distress syndrome subtype of FD)
• The 5-HT1A agonist buspirone and tandospirone have shown benefit for early satiation and impaired gastric accommodation in functional dyspepsia

Antidepressants / Neuromodulators (for Refractory Functional Dyspepsia)

• Low-dose tricyclic antidepressants (e.g., amitriptyline) — modulate visceral hypersensitivity
• SSRIs (escitalopram) have shown mixed results in clinical trials for FD

3. Management by Underlying Cause

4. When to Undergo Endoscopy

• Alarm symptoms are present (see red flags above)
• Age >55 with new-onset dyspepsia
• Symptoms persist after H. pylori treatment and empirical acid-suppression trial
• Recurrent symptoms after treatment

Quick Summary

For mild, occasional burning: try antacids + lifestyle changes. For persistent or frequent symptoms: a PPI trial (4–8 weeks) is the standard empirical first step, with H. pylori testing in most adults. For no structural cause found (functional dyspepsia): combination of H. pylori eradication, PPI, and prokinetics/neuromodulators guided by symptom subtype.
