Esophagitis is the inflammation of the esophagus, the tube that carries food from the mouth to the stomach. This condition can cause symptoms such as pain when swallowing, difficulty swallowing, and chest pain. It can result from various factors, including acid reflux, infections, or irritants like certain medications. Treatment for esophagitis often involves addressing the underlying cause. For example, if acid reflux is the issue, medications may be prescribed to reduce stomach acid. In some cases, dietary changes or avoiding irritants can help alleviate symptoms and promote healing of the esophagus.
