Gastritis is an inflammation and injury of the stomach lining. It is a painful condition and also called dyspepsia. It can occur suddenly (acute) or gradually (chronic). Acute gastritis is more common and lasts for a short duration.


Gastritis can be caused by:

  • Helicobacter pylori:A bacteria that lives in the mucous lining of the stomach. Without treatment, the infection can lead to ulcers and, rarely, stomach cancer.
  • Medications:Medications like aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen
  • Pernicious anemia:A form of anemia that occurs when the stomach lacks a naturally occurring substance that is needed to properly absorb and digest vitamin B12
  • Excessive alcohol use
  • Bile reflux:A backflow of bile (a liquid that is secreted by the liver and helps with digestion) into the stomach
  • Infectionscaused by bacteria and viruses
  • Autoimmune disorders


These can vary but the most common symptoms include:

  • Upper abdominal pain (burning, aching, gnawing or soreness)
  • Nausea
  • Abdominal bloating and fullness
  • Vomiting
  • Indigestion
  • Frequent belching


Based on medical history and physical exam, the following tests can be done to diagnose gastritis

  • Upper GI Series.Abdominal X-ray with contrast to evaluate the stomach
  • Procedure using a thin fiber optic tube with a camera to look at the stomach lining and take a biopsy if needed.
  • Blood test.To check for Helicobacter pylori or anemia
  • Stool test.To check for Helicobacter pylori or blood in your stool


  • Antacids, H-2-receptor blockers, and Proton pump inhibitors:Treatment for gastritis usually involves taking antacids and other drugs like H-2-receptor blockers and dose proton pump inhibitors to reduce stomach acid. These medications will help relieve symptoms and promote healing.
  • Avoiding (NSAIDs)
  • For gastritis caused by Helicobacter pylori, antibiotics are used.
