Gastritis is an inflammation of the lining of the stomach. It has many possible causes.[1] The main causes are drinking too much alcohol, or using nonsteroidal anti-inflammatory drugs (also known as NSAIDs) such as aspirin or ibuprofen for too long. Sometimes gastritis starts after major surgery, serious injury, burns, or infections. People who have had weight loss surgery may also get gastritis. Long term causes are infection with bacteria, mainly Helicobacter pylori. Certain diseases, such as pernicious anemia, chronic bile reflux, stress and certain autoimmune disorders can cause gastritis as well. The most common symptom is abdominal pain. Other symptoms are indigestion, abdominal bloating, nausea, and vomiting. Some may have a feeling of fullness or burning in the upper abdomen.[2][3] A gastroscopy, blood test, complete blood count test, or a faeces test may be used to diagnose gastritis.[4] Treatment includes taking antacids or other medicines, such as proton pump inhibitors or antibiotics, and avoiding hot or spicy foods. For those with pernicious anemia, B12 injections are given.[5]
