Gastritis

Gastritis is cause by inflammation of the lining of the stomach. It is most often the result of infection with the same bacterium that causes most stomach ulcers. Repetitive use of certain pain relievers and consuming too much alcohol can contribute to gastritis.

Gastritis may occur suddenly (acute gastritis) or appear slowly over time (chronic gastritis). In some cases, gastritis can lead to ulcers and an increased risk of stomach cancer. For most people, however, gastritis isn’t serious and improves quickly with treatment.

Symptoms of gastritis could include: burning ache or pain (indigestion) in the upper abdomen, nausea, vomiting, or a feeling of fullness in your upper abdomen after eating.
