Esophagitis (or oesophagitis) is inflammation of the esophagus. It may be acute or chronic. Acute esophagitis can be catarrhal or phlegmonous, whereas chronic esophagitis may be hypertrophic or atrophic.


  • Heartburn (pain in chest/abdomen and may radiate to neck/jaw)
  • Nausea
  • Postprandial worsening of symptoms

Symptoms may be relieved by antacids.



Forms of infectious esophagitis are typically seen in immunocompromised people. Types include:

Endoscopy can be used to distinguish among these conditions.[1]


  • The most common cause is gastroesophageal reflux disease (GERD, or GORD in Standard English). If caused by GERD, the disease is also called reflux esophagitis.
  • Chemical injury by alkaline or acid solutions may also cause esophagitis, and is usually seen in children, as well as in adults who attempt suicide by ingestion of caustic substances[2]
  • Physical injury resulting from radiation therapy or by nasogastric tubes may also be responsible.
  • Pilel esophagitis
  • Hyperacidity
  • Alcohol abuse
  • Eosinophilic esophagitis is a poorly understood form of esophagitis, which is thought to be related to food allergies.
  • Crohn's disease, an autoimmune disease where the immune system inflames the gastrointestinal tract and a type of IBD, can cause oesophagitis if it attacks the oesophagus.
  • Certain medications, including doxycycline may cause oesophagitis if taken incorrectly.

Grading of severity[edit]

The severity of esophagitis is commonly classified into four grades according to the Los Angeles Classification:[3][4]

Grade A One or more mucosal breaks < 5 mm in maximal length
Grade B One or more mucosal breaks > 5mm, but without continuity across mucosal folds
Grade C Mucosal breaks continuous between > 2 mucosal folds, but involving less than 75% of the esophageal circumference
Grade D Mucosal breaks involving more than 75% of esophageal circumference
