What is the cause of esophageal blockage?

Esophageal blockage is mostly caused by esophageal tumor or esophagitis. Patients will feel dysphagia when eating. Such symptoms are typical symptoms of esophageal tumor and esophagitis, and may also be caused by reflux gastritis. Patients with this disease are mainly due to too loose cardia sphincter. Long-term acid reflux will stimulate esophagus, causing esophageal function to decline and showing dysphagia. Therefore, patients will often show esophageal blockage feeling.
