Esophagitis is often caused by stomach fluid that flows back into the food pipe. The fluid contains acid, which irritates the tissue. This problem is called gastroesophageal reflux (GERD). An autoimmune disorder called eosinophilic esophagitis also causes this condition.
The following increase your risk of this condition:
- 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
People who have a weakened immune system may develop infections. Infections may lead to swelling of the food pipe. Infection may be due to:
- Fungi or yeast (most often Candida)
- Viruses, such as herpes or cytomegalovirus
Esophagitis is present when the lining of the esophagus becomes swollen, inflamed, or irritated. The esophagus is the tube that leads from the back of the mouth to the stomach. It is also called the food pipe.
Exams and Tests
The doctor may perform the following tests:
Most of the time, the disorders that cause swelling of the food pipe, respond to treatment.
If not treated, this condition may cause severe discomfort. Scarring (stricture) of the food pipe may develop. This can cause swallowing problems.
A condition called Barrett esophagus (BE) can develop after years of GERD. Rarely, BE may lead to cancer of the food pipe.
The infection or irritation may cause the food pipe to become inflamed. Sores called ulcers may form.
Symptoms may include:
- Difficulty swallowing
- Painful swallowing
- Heartburn (acid reflux)
- Sore throat
Treatment depends on the cause. Common treatment options are:
- Medicines that reduce stomach acid in case of reflux disease
- Antibiotics to treat infections
- Medicines and diet changes to treat eosinophilic esophagitis
- Medicines to coat the lining of the food pipe to treat damage related to pills
When to Contact a Medical Professional
Call your health care provider if you have symptoms of esophagitis.
