The main symptoms of reflux esophagitis include upper abdominal pain, chest pain, belching, acid reflux, nausea, and vomiting. By conducting an endoscopy, the diagnosis of reflux esophagitis can be confirmed if the mucous membrane of the esophagus shows signs of hyperemia, edema, erosion, and ulcers. Treatment mainly involves acid suppression and gastric protection, promoting motility, and mucosal repair, which generally takes six to eight weeks. Dietary adjustments are also important, focusing on a bland and easily digestible diet. It is recommended to avoid spicy, stimulating, fried, grilled, and baked foods, as well as reducing sweet foods. Consumables such as porridge, soup, or noodles, which are easier to digest, are advised.
