Treatment starts with taking charge of the factors responsible for the onset of gastritis (when we know them!). Thus, the doctor may suggest stopping the NSAIDs involved until the symptoms disappear. 

In acute gastritis, which usually lasts only a few days, the doctor may encourage his patient to take liquid meals, which allow the stomach to rest. Antacids can provide relief. 

In the event of chronic gastritis, the management is different. If it is due to the presence of the bacteria Helicobacter pylori, antibiotic treatment is started (eg amoxicillin and clarithromycin). To this can be added gastric dressings, pain medications or drugs that reduce gastric acidity such as histamine H2 receptor inhibitors also called H2 antihistamines or proton pump inhibitors (PPIs such as esomeprazole, lansoprazole, omeprazole, pantoprazole and rabeprazole).
