Gastritis symptoms

2-minute read

Gastritis is when the stomach lining becomes inflamed. This can happen when something – such as certain bacteria or medicines – irritates the lining.

The irritation may also cause the stomach lining to erode (wear down) and become thinner.

Not everyone with gastritis will experience symptoms. If you have symptoms, they may include:

  • a burning pain in your upper stomach area (such as in heartburn) — which may improve or worsen with eating
  • nausea
  • vomiting
  • loss of appetite
  • bloating and burping
  • hiccups
  • diarrhoea

While most gastritis symptoms aren’t serious, it’s especially important you see your doctor if you have any of the following:

  • gastritis symptoms that last more than a week
  • vomiting blood or black, tarry substance (dried blood)
  • blood in your stool (poo), or stool that is black

These symptoms can suggest stomach ulcers or bleeding, or that there is another serious health underlying health condition. While rare, gastritis can also increase the risk of stomach cancer.

To confirm the cause of your symptoms, your doctor is likely to talk to you and examine you. Your doctor may also ask you to have some tests, such as blood tests, breath tests or stool tests.

Your doctor may also refer you to a specialist who is an expert in the digestive tract (gastroenterologist).

You may also be asked to have an endoscopy. An endoscopy involves inserting a flexible tube with a tiny camera down your throat into your upper digestive tract to have a look for signs of inflammation and ulcers. This is usually done with some sedation.

If you suspect you have gastritis — especially if the symptoms are lasting longer than a week or you suspect blood in your stool — see your doctor as soon as possible.
