Antibiotics – doxycycline and tetracycline
Quinidine
Bisphosphonates – used to treat osteoporosis
Steroids
Potassium chloride

Chemical injury by alkaline or acid solutions
Physical injury resulting from nasogastric tubes. Alcohol use disorder – Can wear down the lining of the esophagus. Crohns disease – a type of IBD and an autoimmune disease that can cause esophagitis if it attacks the esophagus. Stress – Can cause higher levels of acid reflux
Radiation therapy - Can affect the immune system. Allergies (food, inhalants) – Allergies can stimulate eosinophilic esophagitis. Infection - People with an immunodeficiencies have a higher chance of developing esophagitis. Vitamins and supplements (iron, vitamin C, and potassium) – Supplements and minerals can be hard on the GI tract. Vomiting – Acid can irritate esophagus. Hernias – A hernia can poke through the diaphragm muscle and can inhibit the stomach acid and food from draining quickly. Surgery
Eosinophilic esophagitis, a more chronic condition with a theorized autoimmune component

Mechanism
The esophagus is a muscular tube made of both voluntary and involuntary muscles. It is responsible for peristalsis of food. It is about 8 inches long and passes through the diaphragm before entering the stomach. The esophagus is made up of three layers:  from the inside out, they are the mucosa, submucosa, muscularis externa. The mucosa, the inner most layer and lining of the esophagus, is composed of stratified squamous epithelium, lamina propria, and muscularis mucosae. At the end of the esophagus is the lower esophageal sphincter, which normally prevents stomach acid from entering the esophagus.
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.
