Esophagitis refers to any inflammation, irritation, or swelling of the esophagus. The esophagus is the tube that leads from the back of the mouth to the stomach.


Esophagitis is often caused by stomach fluid that flows back into the esophagus. The fluid contains acid which irritates the tissue. This problem is 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 medicines without drinking plenty of water. These medicines include alendronate, doxycycline, ibandronate, risedronate, tetracycline, potassium tablets, and vitamin C
  • Vomiting

People who have a weakened immune system may develop infections that lead to esophagitis. Infection may be due to:

  • Fungi or yeast (most often Candida)
  • 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:

  • Cough
  • Difficulty swallowing
  • Painful swallowing
  • Heartburn (acid reflux)
  • Hoarseness
  • Sore throat

Exams and Tests

The doctor may perform the following tests:


Treatment depends on the cause.

  • For reflux disease, you may need to take medicines that reduce stomach acid.
  • Infections will need to be treated with antibiotics.
  • Eosinophilic esophagitis is treated with medication and possibly eliminating certain foods from your diet.

Outlook (Prognosis)

Most of the time, the disorders that cause esophagitis respond to treatment.

Possible Complications

If untreated, esophagitis may cause severe discomfort. Scarring (stricture) of the esophagus may develop. This can cause swallowing problems.

A condition called Barrett's esophagus can develop after years of gastroesophageal reflux. Rarely, Barrett's esophagus may lead to cancer of the esophagus.

When to Contact a Medical Professional

Call your health care provider if you have symptoms of esophagitis.
