Patients with esophagitis can experience pain in the anterior chest area, known as heartburn, which manifests as burning pain in the anterior chest or esophageal region. It usually occurs in episodic attacks, so it is generally believed that esophagitis can cause chest pain, which needs to be differentiated from chest pain caused by coronary heart disease. The diagnosis of esophagitis mainly relies on gastroscopy. For some typical patients, it is recommended that they complete a gastroscopy in a timely manner. Under gastroscopy, inflammatory changes in the esophageal mucosa can be observed, manifested as congestion, edema, erosion, or even ulcer formation. The treatment of esophagitis mainly involves adjusting medication choices and dietary adjustments. Dietary recommendations include a light diet, and medications may include those that reduce acid and protect the mucosa and improve gastrointestinal motility. A typical course of treatment would be two to four weeks, and most patients can achieve relief. (The use of medications should be carried out under the guidance of a doctor.)
