Eosinophilic Oesophagitis is caused by too many eosinophils in the Oesophagus. This happened when your body overrespond to an allergen. In children, this can make eating difficult. According to the Boston Children’s Hospital, 1 in 10,000 children has this form of Oesophagitis. Common triggers include:
- tree nuts
Inhaled allergens, such as pollen, can also contribute to this form of esophagitis.
Reflux Oesophagitis is usually due to a condition known as gastroesophageal reflux disease (GERD). GERD occurs when stomach contents like acids, frequently back up into the Oesophagus. This causes chronic inflammation and irritation of the Oesophagus.
Drug-induced Oesophagitis can occur when you take certain medications without enough water. This causes medications to linger in the Oesophagus too long. These medications include:
- pain relievers
- potassium chloride
- bisphosphonates (drugs that prevent bone loss)
Infectious Oesophagitis is rare and can be due to bacteria, viruses, fungi, or parasites. You are at increased risk for this type of Oesophagitis if you have a weakened immune system due to disease or medications. This type is common in people with HIV or AIDS, cancer, and diabetes.
