Esophagitis is a condition characterized by inflammation or irritation of the esophagus, which is the tube that connects the throat to the stomach. This inflammation can be caused by various factors such as acid reflux, infections, allergies, or certain medications. Symptoms of esophagitis may include difficulty swallowing, chest pain, heartburn, and a feeling of food being stuck in the throat. Treatment for esophagitis typically involves addressing the underlying cause, such as avoiding trigger foods, taking medications to reduce stomach acid, and making lifestyle changes. In severe cases, procedures or surgery may be necessary to repair any damage to the esophagus.
