Treatment for gastritis depends on the root cause but may include antibiotic medications, acid-blocking medications, proton pump inhibitors and antacids, states Mayo Clinic. If the gastritis results from alcohol or nonsteroidal anti-inflammatory drugs, treatment may include halting use of the substance. Lifestyle changes can also treat gastritis.
In cases of chronic gastritis resulting from an H. pylori infection, a 10- to 14-day course of antibiotics, such as amoxicillin and clarithromycin, may be necessary, according to Mayo Clinic. The doctor may also prescribe proton pump inhibitors to block the acid-producing action of cells, although long-term use of these medications may increase the risk of certain fractures. Prescription and over-the-counter histamine blockers are another option, reducing the release of acid in the digestive tract. Antacids may be useful in relieving symptoms quickly by neutralizing existing stomach acid, but side effects may include diarrhea and constipation.
Certain lifestyle remedies, such as eating smaller, more frequent meals, may provide symptom relief, confirms Mayo Clinic. Avoiding alcohol as well as acidic, spicy and fatty foods that irritate the stomach may also be helpful. Managing stress with calming activities, such as meditation or yoga, can help manage gastritis symptoms, and patients can avoid aggravating stomach issues by switching to alternative pain relievers, such as acetaminophen, under a doctor's supervision.
