Gastritis and reactive gastropathy: what does the report mean?

Gastritis and reactive gastropathy describe different changes in the stomach lining. Gastritis means inflammation. Reactive gastropathy is a pattern of injury and repair, often with little inflammation. I check the biopsy, your symptoms, medicines and H. pylori result before recommending treatment.

What I check before recommending treatment

Gastritis is a common finding and is not usually concerning or responsible for significant symptoms on its own. Sometimes gastritis is more significant, so I check for causes such as H. pylori and medicines that may be contributing.

Its upper fundus lies above and to the patient's left of the junction. The lower stomach narrows to the pylorus on the patient's right, then joins the duodenal bulb and C-shaped duodenum. A short continuation is explicitly labelled as later small bowel not shown. No pancreas, gallbladder, entire small bowel or camera route is drawn.

Where is the stomach?

The food pipe enters the stomach. The outlet leads to the duodenum, the first part of the small bowel. Gastroscopy assesses the lining; selected biopsies assess tiny samples under a microscope.

Where is the stomach?

The food pipe enters the stomach. The outlet leads to the duodenum, the first part of the small bowel. Gastroscopy assesses the lining; selected biopsies assess tiny samples under a microscope.

Inflammation or reactive injury?

Gastritis means inflammation. Reactive gastropathy describes an injury-and-repair pattern, often with little inflammation. Mild redness or mild gastritis is common and is usually not concerning on its own. These are independent examples, not stages or diagnoses based on symptoms.

Specific tests are requested to answer a question.

H. pylori testing, biopsies and blood tests are chosen for the question we need to answer. Medicines can affect infection tests. A negative stool test does not replace a gastroscopy recommended for another reason.

What follow-up is useful?

Mild redness or reactive changes are common and do not usually imply any major pathology. Persistent symptoms should be discussed in clinic. Atrophy or intestinal metaplasia is not cancer, but can be relevant to long-term management. Sometimes monitoring is recommended depending on the extent of the changes and your other risks. Your individual recommendation is documented in the endoscopy and/or histology report.

What do gastritis and gastropathy mean?

At gastroscopy, I can see redness, small surface breaks (erosions), ulcers or changes in the folds. Mild redness or mild gastritis is common and is usually not concerning on its own. Redness alone is non-specific: it does not reliably show the cause, prove significant inflammation or tell us how much discomfort you should have.

A biopsy examines tiny samples under a microscope. It can identify inflammation, infection or more specific changes. Not every mildly red stomach needs biopsies. Samples are selected when they can answer a useful clinical question.

Does this explain my indigestion?

Gastritis or gastropathy may cause no symptoms. Some people with gastritis have upper abdominal discomfort, nausea or reduced appetite. You may hear the term dyspepsia used to describe symptoms such as upper abdominal pain or burning, early fullness or uncomfortable fullness after meals. Dyspepsia is not equivalent to gastritis.

If a minor lining change does not explain persistent symptoms, I review the symptom pattern and treatment response. Reflux, functional dyspepsia, gallstones and other conditions may need consideration. We can discuss persistent or changing symptoms in clinic.

How I choose treatment

If a specific cause for gastritis or gastropathy is identified, we can treat or remove that cause where possible. H. pylori is a bacterial infection that can cause chronic gastritis and ulcers.

Anti-inflammatory pain medicines such as ibuprofen or naproxen can damage the protective lining. Alcohol and bile coming back into the stomach can also contribute to reactive changes.

Bring a list of prescribed medicines, pharmacy purchases and supplements. I check the reason for each medicine as well as possible stomach effects. Do not stop prescribed aspirin or a blood thinner yourself. Its benefit and bleeding risk need to be considered together.

Acid medicine does not clear H. pylori

Some people with gastritis have H. pylori infection. This is usually treated with a prescribed course of antibiotics, often with acid suppression. Omeprazole alone is not sufficient to cure H. pylori reliably, although it can suppress the infection and affect test results.

Omeprazole, famotidine and domperidone are among the medicines that may be used to help manage dyspepsia symptoms. Omeprazole may help symptoms and allow erosions or ulcers to heal, but it does not treat every cause of stomach injury.

Current NZ advice is to confirm clearance after H. pylori treatment, even if you feel better. Follow the timing and medicine instructions agreed with your prescriber. The linked H. pylori guide explains this in more detail.

What if the biopsy says atrophy or intestinal metaplasia?

Sometimes biopsies show gastritis and/or findings such as atrophy or intestinal metaplasia. Atrophy means loss of the stomach's usual glands. Intestinal metaplasia means some lining cells have changed to an intestinal type.

This is not cancer, but it can be relevant to long-term management. These findings are different from simple reactive injury. Sometimes monitoring is recommended, depending on how extensive the changes are and your other risks.

Autoimmune gastritis is a separate condition in which the immune system attacks parts of the stomach lining. I may check iron, vitamin B12 and selected antibodies when the findings suggest it. Treating a deficiency and assessing the stomach are separate parts of care.

Food, medicines and the next step

There is no single gastritis diet. Notice foods or drinks that consistently worsen symptoms, but avoid a very restricted diet without a clear reason. Most gastritis is not caused by ordinary food choices. Reducing alcohol and reviewing potentially irritating medicines may help when they contribute.

Mild redness or reactive changes are common and do not usually imply any major pathology. Discuss persistent symptoms in clinic. An ulcer, extensive atrophy, intestinal metaplasia or other findings may justify a different plan.

International guidance considers the extent of changes, family history and other risk factors when deciding whether monitoring is useful. Your recommended endoscopic follow-up will be documented in the endoscopy and/or histology report once tissue results are available.

When to get help

Vomiting blood or material that looks like coffee grounds, black sticky tar-like poo, severe or worsening abdominal pain, or faintness needs urgent medical assessment. Do not assume this is ordinary gastritis or wait for a routine appointment.

Arrange prompt medical review for difficulty swallowing, repeated vomiting, unexplained weight loss or new iron-deficiency anaemia. Tell your GP or our team if symptoms persist or change despite treatment.

Call 111 if you collapse, have significant bleeding with faintness, or are too unwell to travel safely.

Three things to remember

  • Redness on the camera, inflammation on biopsy and reactive injury are different findings.
  • Treatment depends on the cause. Acid suppression alone does not clear H. pylori.
  • I recommend follow-up after reviewing the endoscopy, biopsy result and your history.
