Doctor's Notes on Gastritis

Gastritis is a term that refers to inflammation of the stomach lining due to any cause. Gastritis may come on suddenly (acute) or develop and persist over time (chronic). There are two main causes of gastritis: infection with a bacterium called Helicobacter pylori (H. pylori) and taking and nonsteroidal anti-inflammatory drugs (NSAIDs).  Other diseases and conditions can less commonly cause the condition.

Some people do not have symptoms of gastritis. When symptoms do occur, signs and symptoms associated with gastritis include:

  • Antacid medications or other medications like H2 blockers or proton pump inhibitors that decrease stomach acid
  • Antibiotics if an H. pylori infection is present
  • Avoiding spicy foods and any other foods that cause symptoms or irritation
  • Vitamin B12 shots, if the gastritis is caused by a condition known as pernicious anemia
  • Avoiding pain relievers that may worsen the condition
