What are the first signs of gastritis?

Gastritis means irritation or inflammation of the stomach lining. Early symptoms may include burning or aching [Abdominal Pain](/symptoms/abdominal-pain/), [Indigestion](/symptoms/indigestion/), nausea, belching, feeling full quickly, or [Loss of Appetite](/symptoms/loss-of-appetite/). Some people have few symptoms even when the lining is inflamed.

Possible contributors include infection with [Helicobacter Pylori Infection](/conditions/helicobacter-pylori-infection/), irritation from alcohol, and some medicines. Symptoms alone cannot identify the cause, and persistent discomfort should not automatically be labelled gastritis.

Keep track of pain, meals, alcohol, medicines, nausea, and appetite. Avoid alcohol and foods that clearly worsen your discomfort while arranging an assessment. Do not stop a prescribed medicine without advice, even if you suspect it is irritating your stomach.

A clinician may consider an [H. Pylori Breath Test](/treatments/diagnostics-and-screening/h-pylori-breath-test/) or discuss [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) when appropriate. The right option depends on the symptoms and examination.

Seek urgent help for vomiting blood, black stools, severe or rapidly worsening abdominal pain, fainting, chest pain, or inability to keep fluids down. Arrange prompt medical review for ongoing vomiting, progressive loss of appetite, or unexplained weight loss.

Could an infection, medicine, alcohol, reflux, or another condition explain my symptoms? Do I need testing for H. pylori? Which treatments are suitable, and which warning signs should I watch for?
