A number of conditions can cause esophageal dysphagia, such as:

  • Achalasia —affects the muscles at the bottom of the esophagus
  • Scleroderma —causes thickening and stiffening of tissues, joints, and organs; can lead to problems with the esophageal muscles
  • Esophageal stricture or esophageal ring—causes the esophagus to become more narrow
  • Esophageal tumors
  • Infectious esophagitis
  • Caustic esophagitis
  • Foreign bodies
  • Eosinophilic esophagitis
