The common symptoms of chronic gastritis include upper abdominal bloating, belching, acid reflux, nausea, vomiting, poor appetite, and indigestion. A gastroscopy can be performed to confirm the diagnosis; if the gastroscopic examination reveals redness, swelling, and erosion of the gastric mucosa, a diagnosis of chronic gastritis can be made. The main treatment includes acid suppression and gastric protection, promoting gastric motility, and protecting the gastric mucosa, with a treatment course of about four to six weeks. It is also recommended to conduct a carbon-14 breath test to determine if there is an infection with Helicobacter pylori. If the infection is positive, a 14-day treatment for Helicobacter pylori is necessary, using a proton pump inhibitor plus two antibiotics and a bismuth agent. Additionally, it is advised to consume easily digestible food, increase physical activity, avoid overworking and staying up late, and avoid feelings of anxiety and depression.
