Gastritis
How is gastritis diagnosed?
After asking about your symptoms and medical history, your doctor may recommend the following diagnostic tests:
Helicobacter pylori (H. pylori) breath test
To test if you have H. pylori bacterial infection, you will take a capsule or liquid with urea. Urea is a radioactive material that is safe to ingest.
You will then breathe into a balloon-like bag. If there is an increase in carbon dioxide levels, this means that you have an H. pylori infection.
Upper endoscopy
In this procedure, a long thin tube with a camera called an endoscope will be inserted into your throat, down your oesophagus and stomach. Endoscopy allows your doctor to:
- View and examine your stomach lining
- Gather some stomach tissue samples to test for infection
Blood test
Blood tests may be required to check your red blood cell count. In some cases, gastritis causes gastrointestinal bleeding that may lead to anaemia. Blood tests can also help screen for a H. pylori infection.
Stool test
Your doctor may also require a stool test. Blood in the stools can be a sign of gastritis.
Upper gastrointestinal tests
Upper gastrointestinal (GI) exams are useful in checking your oesophagus, stomach, and part of the small intestine. Types of upper GI tests include:
- Oesophagography or X-ray of the oesophagus
- X-ray examination of the stomach
- X-ray examination of the small intestine
How is gastritis treated?
Depending on the cause of your gastritis, your doctor will suggest the most suitable treatment. Treatment options can include:
Acid control medication
You may be given acid control medications to neutralise acid levels in the stomach. Examples of these medications include antacids, histamine (H2) blockers, and proton pump inhibitors.
Antibiotics
If your gastritis is caused by the H. Pylori bacteria, you will be given antibiotics.
Pain relief
To manage your gastritis symptoms, you may be given pain medications, such as those containing acetaminophen.
