Acute gastritis generally recovers slowly over about a week with active treatment. During the treatment period, attention should be paid to the treatment of the cause and symptomatic treatment. Mainly, the patient should rest in bed and stop all food or medicine that irritates the stomach. Additionally, medications that relieve spasms and pain, protect the gastric mucosa, and suppress gastric acid secretion should be used. Acute gastritis often occurs with enteritis; if vomiting and diarrhea are frequent, oral rehydration should be administered promptly, and more severe cases may require intravenous fluids. During treatment, dietary adjustments should be considered, including eating soft, easily digestible foods. If vomiting is frequent, the patient should refrain from eating and drink more water, consuming more vegetables to supplement dietary fiber.
