People with esophagitis tend to experience emaciation. Esophagitis, medically referred to as gastroesophageal reflux disease (GERD), is characterized by symptoms such as upper abdominal distension, chest pain, belching, acid reflux, nausea, vomiting, and indigestion. Due to the long-term presence of these symptoms, appetite can decrease, leading to emaciation in patients with GERD. During an endoscopy, if erosions in the gastric mucosa are observed, a diagnosis of gastroesophageal reflux disease can be made. Based on the extent of these erosions, the condition can be classified into four grades, from A to D, with grade A being the mildest and grade D the most severe. Treatment mainly involves promoting gastric motility, repairing the mucosa, and acid-suppressing and stomach-protecting therapies, generally requiring about an eight-week treatment period.
