- Gastroesophageal reflux disease – The most common cause, with symptoms resulting from a combination of refluxed gastric acid and pepsin leading to inflammation and ultimately necrosis of the esophageal wall, causing ulcers and erosions.
- Infectious esophagitis – Common in patients with immunodeficiency or those on immunosuppressive medications. Common infections include Candida spp., herpes simplex virus type 1 or 2, varicella zoster virus, and cytomegalovirus, especially in organ-transplant recipients.
- Radiation esophagitis – Develops after treatment for thoracic cancers, especially breast cancer, with the risk proportional to the radiation dosage. Symptoms may last weeks to months after the completion of therapy. Stricture is a common consequence.
- Corrosive esophagitis – Follows ingestion of alkali or acidic materials. Stricture is a common consequence of this time of injury and may require dilation.
