Acute gastritis is an acute lesion occurring in the gastric mucosa, which can cause significant abdominal pain. Mucosal rupture and bleeding can lead to gastric bleeding, and if there is a substantial amount of bleeding, it may cause vomiting blood. Chronic gastritis is a long-term, diffuse inflammation of the stomach, with the main symptoms being loss of appetite, abdominal pain, belching, and acid reflux.

Relatively speaking, the symptoms of acute gastritis are more severe. The treatment for acute gastritis primarily involves the use of medications that suppress gastric acid secretion and protect the gastric mucosa. In terms of diet, it is important to eat cautiously, avoiding spicy and greasy foods, consuming more vegetables, and eating meals regularly and in moderation.

(The use of medications should be under the guidance of a doctor.)
