In clinical practice, the diagnosis of esophagitis mainly relies on gastroscopy. Therefore, it is generally believed that patients with esophagitis are advised to undergo a comprehensive gastroscopy to confirm the diagnosis. Patients with esophagitis usually consult the gastroenterology department, presenting typically with symptoms like acid reflux and heartburn. Some patients may also experience nausea, belching, or dysphagia. Heartburn typically manifests as a burning pain in the chest or esophageal area, occurring episodically and generally related to diet, with episodes more commonly occurring after meals. The diagnosis of esophagitis relies on gastroscopy. Treatment options include dietary adjustments and selecting appropriate medications. Dietary recommendations involve consuming easily digestible and clean foods, avoiding overeating, and cultivating good living habits. Medications can include acid reducers, mucosal protectants, and agents that improve gastrointestinal motility. (The use of medications should be under the guidance of a doctor.)
