Acute gastritis is a relatively common disease, and if not treated actively, the symptoms can be quite severe. This is because acute gastritis can lead to damage to the gastric mucosa, causing erosion of the mucosa, or symptoms such as bleeding and perforation of the gastric mucosa, leading to severe symptoms. For acute gastritis, active treatment is necessary, primarily involving the use of medications to protect the gastric mucosa and inhibit gastric acid secretion, as well as appropriately selecting antibiotics. If there is an associated Helicobacter pylori infection, it is necessary to completely eradicate the Helicobacter pylori. Additionally, dietary adjustments should be made, such as eating more vegetables and fruits and avoiding spicy foods.
