The main symptoms of gastroesophageal reflux disease include upper abdominal pain, chest pain, belching, acid reflux, nausea, and vomiting. A gastroscopy can reveal lesions on the esophageal mucosa, and if such damage is observed, a diagnosis of gastroesophageal reflux disease can be made. The severity of the lesions on the esophageal mucosa can be classified into four grades: A, B, C, and D, with grade A being the mildest and grade D the most severe. Treatment primarily involves acid suppression, promoting gastric motility, and repairing the mucosa. The treatment course usually lasts about six to eight weeks. Moreover, gastroesophageal reflux disease is closely related to poor gastric motility, so regular exercise is recommended. Exercise can enhance gastric motility and promote intestinal peristalsis, which plays a positive role in the treatment of gastroesophageal reflux disease.
