Gastritis is divided into acute gastritis and chronic gastritis. Common types of chronic gastritis include chronic superficial gastritis and chronic atrophic gastritis, which do not affect eating. Treatment plans are determined based on diagnostic results and whether there is a Helicobacter pylori infection. Treatment can be achieved through oral medication, so in these cases, infusion therapy is generally not necessary. If it is acute gastritis, accompanied by severe vomiting and inability to eat, this situation often requires infusion therapy, such as proton pump inhibitors for infection control, and supplementation of water and electrolytes to achieve therapeutic effects.
