How to Treat Bloating, Indigestion, and Food Stagnation

Gastric distension, food stagnation, and impaired digestion—commonly experienced as persistent upper abdominal fullness, bloating, early satiety, nausea, or belching—are not standalone diagnoses but rather symptomatic manifestations of underlying gastrointestinal dysfunction. These symptoms may arise from functional dyspepsia, gastroparesis, chronic gastritis, small intestinal bacterial overgrowth (SIBO), or even subtle motility disorders affecting gastric emptying.

Effective management begins with thorough clinical evaluation to rule out organic causes—including endoscopy, gastric emptying scintigraphy, breath testing for SIBO, or serologic assessment for celiac disease or Helicobacter pylori infection. Empiric proton pump inhibitor (PPI) therapy is appropriate only if reflux-related features coexist; indiscriminate PPI use in non-erosive, motility-driven cases may worsen symptoms by altering gastric pH and microbiota.

First-line nonpharmacologic interventions include dietary modification—such as reducing intake of fermentable oligo-, di-, monosaccharides and polyols (FODMAPs), limiting high-fat and high-fiber meals, and adopting smaller, more frequent meals. Behavioral strategies like mindful eating, upright posture during and after meals, and avoidance of lying down within three hours of eating support physiological gastric clearance.

Pharmacologic options depend on the presumed pathophysiology. Prokinetic agents—such as low-dose erythromycin (acting on motilin receptors) or prucalopride (a selective 5-HT₄ agonist)—may be considered for documented delayed gastric emptying. In cases linked to visceral hypersensitivity or central modulation, low-dose tricyclic antidepressants (e.g., amitriptyline) or selective serotonin reuptake inhibitors (SSRIs) may provide symptom relief independent of mood effects. Herbal formulations like *Bao He Wan* have shown modest benefit in randomized trials for functional dyspepsia, though evidence remains limited and quality-controlled.

Long-term resolution hinges on identifying and addressing root contributors—whether metabolic (e.g., poorly controlled diabetes), neurological (e.g., Parkinson’s disease), pharmacologic (e.g., anticholinergics, opioids), or psychosocial (e.g., chronic stress, anxiety). Multidisciplinary care involving gastroenterologists, dietitians, and behavioral health specialists often yields superior outcomes compared to isolated pharmacotherapy.
