Indigestion (Dyspepsia): Causes and Effective Treatments
Indigestion (dyspepsia) is a common gastroenterological complaint that presents with upper abdominal pain, burning, bloating, and early satiety, and affects 20–30% of the population. This guide covers the distinction between functional and organic dyspepsia, diagnostic approaches, and evidence-based treatment options.
- Epigastric pain: pain or burning in the central upper abdomen
- Epigastric burning: burning sensation in the stomach region
- Postprandial fullness: uncomfortably full feeling after meals
- Early satiety: feeling full before finishing a normal-sized portion
- Postprandial distress syndrome (PDS): post-meal fullness and early satiety predominate
- Epigastric pain syndrome (EPS): epigastric pain and burning predominate
- Peptic ulcer disease: gastric or duodenal ulcer (the most common cause)
- Gastroesophageal reflux disease (GERD): dyspepsia and GERD frequently overlap
- Gastritis: inflammation of the stomach mucosa (particularly H. pylori–related)
- Gastric cancer: rare but serious — should be considered especially in patients over 55 with alarm symptoms
- Gallbladder disease: gallstones, cholecystitis
- Medications: NSAIDs (ibuprofen, aspirin), antibiotics, iron preparations
- Pancreatitis: acute or chronic pancreatic inflammation
- Celiac disease: should be investigated particularly in refractory dyspepsia
- Urea breath test: non-invasive, high sensitivity and specificity (>95%)
- Stool antigen test: non-invasive, practical
- Endoscopic biopsy: rapid urease test, histology, culture
- Serology: indicates past infection; not suitable for evaluating treatment response
- Unintended weight loss (more than 5%)
- Difficulty swallowing (dysphagia) or painful swallowing (odynophagia)
- Recurrent vomiting
- Signs of gastrointestinal bleeding (melena, hematemesis, iron deficiency anemia)
- Epigastric mass
- Family history of gastric cancer
- Test for H. pylori (urea breath test or stool antigen test)
- If positive, give eradication therapy
- If negative, or if symptoms persist after eradication, start empirical PPI therapy
- If there is no response to 8 weeks of PPI therapy, plan endoscopy
- Clarithromycin-based triple therapy: PPI + clarithromycin + amoxicillin (14 days)
- Bismuth-based quadruple therapy: PPI + bismuth subsalicylate + metronidazole + tetracycline (14 days)
- Concomitant therapy: PPI + amoxicillin + clarithromycin + metronidazole (14 days)
- Use: standard dose, once daily, in the morning on an empty stomach, 30 minutes before food
- Treatment duration: 4–8 weeks
- Assessment of response: if symptoms have not improved at 4 weeks, the dose can be increased or endoscopy planned
- Metoclopramide: dopamine antagonist; effective in nausea and gastroparesis, but carries the risk of extrapyramidal side effects with long-term use
- Domperidone: crosses the blood–brain barrier less so neurological side effects are fewer; however, must be used cautiously because of QT prolongation risk
- Itopride: used in some countries for functional dyspepsia
- Eat small and frequent meals: prefer 5–6 small meals per day; large portions cause gastric distension and worsen symptoms
- Eat slowly: chew each bite well; fast eating leads to swallowing air and early satiety
- Avoid trigger foods: fatty foods, spicy dishes, onions, garlic, tomato sauce, citrus fruits, chocolate, mint, carbonated drinks
- Limit alcohol and caffeine: both increase gastric acid secretion and irritate the gastric mucosa
- Don't lie down right after eating: there should be at least 3 hours between the last meal and going to bed
- Quit smoking: smoking weakens the protective mechanisms of the gastric mucosa and increases ulcer risk
- Stress management: chronic stress increases gastric acid secretion and visceral sensitivity. Regular exercise, meditation, and deep-breathing techniques are helpful.
- Weight control: obesity contributes to dyspepsia and reflux by raising intra-abdominal pressure
- Medication review: drugs that can cause dyspepsia — NSAIDs, aspirin, iron, calcium, bisphosphonates — should be stopped if not necessary, or replaced with alternatives
- Presence of any alarm symptom (weight loss, dysphagia, bleeding, vomiting)
- New-onset dyspepsia in patients over 55
- Persistent symptoms despite 4–8 weeks of treatment
- Frequently recurring complaints
- Family history of gastric cancer
- Persistent complaints that significantly affect quality of life
