Symptoms of chronic indigestion and retching are mainly considered indicative of chronic gastritis. Common symptoms of chronic gastritis include upper abdominal bloating, belching, acid reflux, nausea, vomiting, poor appetite, indigestion, and heartburn. Gastroscope examination revealing mucosal congestion, edema, or erosion confirms the diagnosis of chronic gastritis. It is also advisable to undergo a Carbon-14 breath test to determine the presence of Helicobacter pylori infection. Helicobacter pylori has been confirmed as a major cause of chronic gastritis, peptic ulcers, and even gastric cancer. If Helicobacter pylori infection tests positive, a 14-day anti-Helicobacter pylori treatment is required, involving a proton pump inhibitor, two antibiotics, and a bismuth agent. Additionally, for chronic gastritis, acid suppression, gastric protection, enhancement of gastric motility, and mucosal repair treatments are also necessary. With standardized treatment, symptoms can disappear, and the disease can be effectively cured.
