Difficulty Swallowing (Dysphagia)

Dysphagia — difficulty swallowing — is a symptom that always warrants evaluation. It can range from a benign Schatzki ring to malignancy, and the workup approach depends on whether the difficulty is with solids, liquids, or both, and whether symptoms are intermittent or progressive.

Types of Dysphagia

Oropharyngeal dysphagia

Difficulty initiating a swallow, coughing, choking, or nasal regurgitation. Often related to neurologic conditions (stroke, Parkinson's, ALS), structural problems (Zenker's diverticulum), or muscle weakness. Initial workup typically includes a videofluoroscopic swallow study with a speech-language pathologist.

Esophageal dysphagia

Sensation of food sticking after swallowing — usually a few seconds after the swallow begins. The pattern of symptoms helps narrow the differential:

• Solids only, intermittent: Schatzki ring, esophageal web, or eosinophilic esophagitis
• Solids only, progressive: peptic stricture (from chronic GERD) or esophageal cancer — especially with weight loss or alarm features
• Solids and liquids, intermittent or progressive: motility disorder — achalasia, distal esophageal spasm, ineffective motility

Common Causes

Eosinophilic esophagitis (EoE)

An immune-mediated inflammatory condition increasingly recognized as a major cause of dysphagia and food impaction in young adults. Diagnosis requires endoscopy with biopsies (≥15 eosinophils per high-power field). Treatment includes PPI, topical steroids (budesonide, fluticasone), dietary elimination, and dilation when stricture is present.

Peptic stricture

A narrowing of the lower esophagus from chronic GERD-related inflammation. Treated with PPI plus endoscopic dilation. See the esophageal dilation page for procedure details.

Schatzki ring

A thin mucosal ring at the squamocolumnar junction. Classically presents with intermittent solid-food dysphagia. Treated with single-pass dilation, usually with excellent durability.

Achalasia

A primary motility disorder with failure of LES relaxation and absent peristalsis. Diagnosed by high-resolution manometry and timed barium esophagram. Treated with pneumatic dilation, peroral endoscopic myotomy (POEM), or laparoscopic Heller myotomy.

Esophageal cancer

Progressive solid-food dysphagia with weight loss in a patient over 50 — particularly with chronic GERD or Barrett's history — warrants prompt endoscopy. Risk factors: chronic GERD, Barrett's esophagus, smoking, alcohol, obesity (adenocarcinoma); smoking and alcohol especially for squamous cell carcinoma.

Diagnostic Approach

• Upper endoscopy (EGD) — first-line study; allows direct visualization, biopsies, and immediate dilation when needed
• High-resolution esophageal manometry — when motility disorder is suspected (achalasia, spasm, ineffective motility)
• Barium esophagram (timed) — useful for achalasia, large hiatal hernia, anatomic abnormalities
• Videofluoroscopic swallow study — for oropharyngeal dysphagia
• pH or pH-impedance testing — when GERD-related symptoms remain unclear

When to Seek Evaluation

Get evaluated promptly for any of the following:

• Progressive dysphagia, especially for solids
• Unintentional weight loss
• Food impaction (food stuck and not passing)
• Coughing or choking with swallowing
• Anemia or GI bleeding
• Chest pain with swallowing

For new dysphagia, do not wait — particularly if you are over 50 or have a history of chronic GERD, Barrett's esophagus, or smoking.
