How Indigestion Remedies Work: Acid Neutralization, Reduction, and Digestive Support

Mechanisms of Common Indigestion (Dyspepsia) Treatments

1. Acid Neutralizers (Antacids)

Calcium carbonate, magnesium hydroxide, aluminum hydroxide. Raise gastric pH instantly. Symptomatic relief for heartburn, sour stomach. Short duration (1–2 hours).

2. Acid Reducers

• H₂ blockers (famotidine, cimetidine): Block histamine H₂ receptors on parietal cells. Onset 30–60 min; duration 8–12 h.
• Proton Pump Inhibitors (PPIs) (omeprazole, esomeprazole): Irreversibly inhibit H⁺/K⁺-ATPase. Max effect after 2–4 days; 24 h coverage. Best for frequent symptoms.

3. Mucosal Protectants

Sucralfate: Forms viscous paste adhering to ulcer/erosion sites, shielding from acid/pepsin. Take on empty stomach.

4. Digestive Enzymes

Pancrelipase, lactase, alpha-galactosidase, bromelain/papain. Aid breakdown of fats, carbs, proteins → less gas/bloating from malabsorption.

5. Prokinetics / Laxatives

• Metoclopramide, domperidone: enhance gastric emptying (gastroparesis)
• Osmotic/stimulant laxatives: relieve constipation-related bloating

Lifestyle Adjuncts

1. Avoid trigger foods (spicy, fatty, caffeine, chocolate, mint, alcohol)
2. Small, frequent meals
3. Hydrate (water, herbal tea)
4. Quit smoking; limit alcohol
5. Head of bed elevated 6–8 inches for nocturnal reflux
6. Regular moderate exercise

If symptoms persist >2 weeks despite OTC use, or alarm features (weight loss, dysphagia, anemia, GI bleeding) appear → endoscopy.
