Painful Swallowing (Dysphagia): 9 Causes and When to See a Doctor

Odynophagia (painful swallowing) and dysphagia (difficulty swallowing) signal esophageal or oropharyngeal pathology. Persistent symptoms warrant prompt evaluation.

Common Causes

1. Infectious/Inflammatory: Tonsillitis, pharyngitis, candidiasis (thrush), herpes esophagitis.
2. GERD/Reflux Esophagitis: Acid/pepsin damage causes burning, pain, strictures over time.
3. Eosinophilic Esophagitis (EoE): Allergic/immune-mediated; food impaction, dysphagia, chest pain.
4. Pill Esophagitis: Medication-induced (bisphosphonates, NSAIDs, antibiotics, potassium) from inadequate water/recumbency.
5. Structural Obstruction: Strictures (peptic, caustic, radiation), Schatzki ring, webs, tumors (benign/malignant).
6. Motility Disorders: Achalasia (failed LES relaxation), diffuse esophageal spasm, jackhammer esophagus, scleroderma.
7. Zenker's Diverticulum: Pharyngeal pouch causing regurgitation, halitosis, aspiration risk.
8. Neuromuscular: Myasthenia gravis, Parkinson's, stroke, ALS affecting swallow coordination.
9. Esophageal Cancer: Progressive dysphagia (solids→liquids), weight loss, odynophagia — urgent evaluation needed.

Diagnostic Workup

• Barium swallow / videofluoroscopic swallow study (VFSS)
• Upper endoscopy (EGD) with biopsy
• Esophageal manometry (motility)
• pH-impedance monitoring (reflux)

Red Flags: Immediate Evaluation

• Unintentional weight loss
• Food sticking/regurgitation
• Hematemesis or melena
• Age >50 with new-onset dysphagia
