What is Gastritis?

Gastritis is a general term for a condition in which the lining of the stomach becomes red and inflamed. A gastritis attack may happen suddenly (acute gastritis) or gradually (chronic gastritis).

Gastritis may cause different symptoms in different people. Some common symptoms include:
  • Steady ache or pain in the upper abdomen
  • Nausea and vomiting
  • A feeling of fullness
  • Loss of appetite
  • Blood in your vomit or stool (which may indicate stomach lining bleeding)

What is the treatment for Gastritis?

For most people gastritis isn't serious and improves quickly with treatment.

Your doctor may order certain tests to determine the cause and extent of the gastritis.

Depending on the specific cause of the gastritis, your doctor may recommend changes in diet or behaviors, or may prescribe medications such as:
