Gastritis is very common. It occurs when the lining of your stomach becomes swollen (inflamed). Gastritis is usually mild and resolves without any treatment. However, gastritis can cause pain in the upper part of your tummy (abdomen) and may lead to a stomach ulcer.

Some simple changes to your lifestyle and using over-the-counter antacid medicines are often all that is required. Other medicines to reduce the acid in your stomach are sometimes needed. Gastritis usually resolves without any problems. However, if not treated properly, gastritis can last a long time or may lead to a stomach ulcer or anaemia.
