Reflux esophagitis can be diagnosed when an endoscopy reveals damage to the gastric mucosa. Its main symptoms include upper abdominal pain, chest pain, belching, acid reflux, nausea, and vomiting. Treatment primarily involves acid suppression, promoting gastric motility, and protecting the mucosa. Since reflux esophagitis is greatly related to poor gastric motility, in addition to pharmacological treatments, increasing physical activity is also necessary because exercise can enhance gastrointestinal motility and strengthen gastric dynamics, playing a crucial role in the treatment and symptom relief of reflux esophagitis. Furthermore, the diet should be light and easy to digest, avoiding spicy, stimulating, fried, grilled, cold, and sweet foods.
