What is the difference between acute and chronic gastritis?

The difference between acute and chronic gastritis includes different etiologies, different course of disease, different typical symptoms, different treatment methods and different prognosis. Details are as follows: 1. Different etiologies Acute gastritis is generally caused by pathogenic microbial infection, drug stimulation and food stimulation. Chronic gastritis is due to Helicobacter pylori infection, immune abnormalities and other reasons, the two factors are different. 2, the length of the course of acute gastritis patients are mostly acute onset, treatment cycle is shorter. Chronic gastritis has a longer course of disease, treatment cycle is relatively long. 3. Different typical symptoms The typical symptoms of patients with acute gastritis are fever, vomiting, diarrhea, etc., most of which are accompanied by systemic symptoms. Chronic gastritis is generally rarely accompanied by systemic symptoms such as fever, headache, myalgia, etc., which are mainly caused by gastrointestinal tract Discomfort symptoms are the main symptoms, and common symptoms include dull upper abdominal pain, loss of appetite and postprandial fullness. 4. Patients with acute gastritis caused by virus infection generally need symptomatic treatment without antiviral treatment or surgical treatment. However, patients with chronic gastritis generally need radical treatment of Helicobacter pylori, and those with irreversible focal high-grade intraepithelial neoplasia should be treated immediately by surgery. The commonly used surgical treatment methods include mucosal dissection and mucosal resection under gastroscope. 5. Prognosis is different. Most acute gastritis belongs to self-limiting diseases with good prognosis. The prognosis of chronic nonatrophic gastritis patients after treatment is better, once intestinal metaplasia occurs, the prognosis is poor.
