When your stomach lining is irritated by bacteria or something you ate or drank, it may swell up (become inflamed) and cause discomfort in your stomach; this reaction is commonly known as gastritis. Gastritis can develop quickly (acute gastritis) or gradually and last for a long time (chronic gastritis).
There are different types of gastritis. In some cases, gastritis can lead to ulcers and an increased risk of stomach cancer. With treatment, however, you can improve quickly and avoid the risk of complications.
The most common symptoms of gastritis include:
- Belching and hiccups
- Belly or abdominal bleeding
- Blood in your vomit or stool (a sign that your stomach lining may be bleeding)
- Feeling of fullness or burning in your stomach
- Gnawing or burning ache or pain in your upper belly that may become either worse or better with eating
- Loss of appetite
- Nausea or vomiting
