In gastrointestinal diseases, chronic gastritis is probably the most common. Its treatment primarily depends on whether there is an infection by Helicobacter pylori. If there is a Helicobacter pylori infection, the treatment mainly involves antibacterial therapy. If there is no infection, symptomatic treatment is sufficient, such as protecting the gastric mucosa and suppressing stomach acid, etc. As for whether chronic gastritis requires intravenous fluids, if the patient does not exhibit significant vomiting symptoms and is able to eat on their own, intravenous fluids are generally not advocated, as oral medications can usually achieve the therapeutic goals. If chronic gastritis acutely flares up with significant vomiting that affects eating, intravenous fluid treatment may be appropriate.
