Esophagitis is a general term for any inflammation, irritation, or swelling of the esophagus, the tube that leads from the back of the mouth to the stomach.

Inflammation - esophagus
Causes, incidence, and risk factors
Esophagitis is often caused by fluid that contains acid flowing back from the stomach to the esophagus, a condition called gastroesophageal reflux. An autoimmune disorder called eosinophilic esophagitis also causes this condition.
The following increase your risk of esophagitis:
- Alcohol use
- Cigarette smoking
- Surgery or radiation to the chest (for example, treatment for lung cancer)
- Taking certain medications without plenty of water, especially alendronate, doxycycline, ibandronate, risedronate, tetracycline, and vitamin C
Persons with weakened immune systems due to HIV and certain medications (such as corticosteroids) may develop infections that lead to esophagitis.
Esophageal infection may be due to fungi, yeast (especially Candida infections), or viruses such as herpes or cytomegalovirus.
The infection or irritation may cause the esophagus to become inflamed. Sores called ulcers may form.
Symptoms may include:
- Difficulty swallowing
- Painful swallowing
- Heartburn (acid reflux)
- Sore throat
Signs and tests
The doctor may perform the following tests:
Treatment depends on the cause. For reflux disease, you may need medications to reduce acid. Infections will need to be treated with antibiotics.
The disorders that cause esophagitis usually respond to treatment.
If untreated, esophagitis may cause severe discomfort, and eventual scarring (stricture) of the esophagus. This can cause difficulty swallowing food or medications.
A condition called Barrett's esophagus can develop after years of gastroesophageal reflux. Rarely, Barrett's esophagus may lead to cancer of the esophagus.
Calling your health care provider
Call your health care provider if you have symptoms of esophagitis.
