Some lifestyle indicators for this disease include stress, unhealthy eating, smoking, drinking, family history, allergies, and immunodeficiency. Types
Reflux esophagitis
Although it usually assumed that inflammation from acid reflux is caused by the irritant action on the mucosa by hydrochloric acid, one study suggests that the pathogenesis of reflux esophagitis may be cytokine-mediated. Infectious esophagitis
Esophagitis happens due to a viral, fungal, parasitic or bacterial infection. More likely to happen to people who have an immunodeficiency. Types include:
Fungal

Candida (Esophageal candidiasis)Viral

Herpes simplex (Herpes esophagitis)
CytomegalovirusDrug-induced esophagitis
Damage to the esophagus due to medications. If the esophagus is not coated or if the medicine is not taken with enough liquid, it can damage the tissues. Eosinophilic esophagitis
Eosinophilic esophagitis is caused by a high concentration of eosinophils in the esophagus. The presence of eosinophils in the esophagus may be due to an allergen and is often correlated with GERD. The direction of cause and effect between inflammation and acid reflux is poorly established, with recent studies (in 2016) hinting that reflux does not cause inflammation. This esophagitis can be triggered by allergies to food or to inhaled allergens. This type is still poorly understood. Lymphocytic esophagitis
Lymphocytic esophagitis is a rare and poorly understood entity associated with an increased amount of lymphocytes in the lining of the esophagus. It was first described in 2006. Disease associations may include Crohns disease, gastroesophageal reflux disease and coeliac disease. It causes similar changes on endoscopy as eosinophilic esophagitis including esophageal rings, narrow-lumen esophagus, and linear furrows. Caustic esophagitis
Caustic esophagitis is the damage of tissue via chemical origin.
Brainerd diarrhea is a sudden-onset watery, explosive diarrhea that lasts for months and does not respond to antibiotics; the cause of Brainerd diarrhea is unknown. Brainerd diarrhea was first described in Brainerd, Minnesota in 1983. It has been associated with the consumption of raw milk and untreated water. Of the ten outbreaks reported since 1983, nine have been in the U.S. The characteristics of each outbreak have been similar to that caused by an infectious agent. Although a comparatively large outbreak (117 patients) occurred in 1996 in Fannin County, Texas., the largest outbreak (122 patients) was the original one in Brainerd, MN. There have been no secondary cases reported in any of the outbreaks, suggesting that the
causative agent cannot be passed from person to person, but boiling water appears to inactivate the Brainerd agent. Although there is no treatment available, the disease does appear to resolve itself, although this process takes months if not years. References
