Gastritis: Symptoms, Causes, Treatment and When to Seek Help

That burning feeling in your upper stomach is not always “just gastrik.” Learn what gastritis is, why it happens and when a medical assessment matters.

Key points at a glance

Gastritis means inflammation of the stomach lining, and some people have no symptoms at all.

Helicobacter pylori (H. pylori) infection and certain painkillers are important causes.

Treatment depends on the cause. Vomiting blood, black tarry stools or sudden severe pain require emergency attention.

In Malaysia, people often use the word gastrik to describe upper abdominal discomfort. But indigestion, acid reflux, peptic ulcers and gastritis are not the same condition. Understanding the cause of your symptoms can help you get the right treatment.

What is gastritis?

Gastritis is inflammation of the protective lining inside your stomach. It may be acute, appearing suddenly, or chronic, developing gradually or persisting over time. Inflammation can sometimes damage the lining and increase the risk of ulcers or bleeding.

AcuteAppears suddenly
ChronicDevelops gradually or persists over time

Not every episode of stomach discomfort is gastritis. Acid reflux (GERD), functional indigestion and peptic ulcers may produce similar sensations but require different approaches. A clinician can help determine what is actually causing the symptoms.

What are the symptoms of gastritis?

Many people with gastritis have no noticeable symptoms. When symptoms do occur, they may include:

  • Aching, burning or discomfort in the upper abdomen
  • Feeling bloated or uncomfortably full after eating
  • Nausea or vomiting
  • Loss of appetite
  • Indigestion or a feeling of early fullness
These symptoms are not specific to gastritis. Persistent or recurring discomfort should be assessed rather than repeatedly self-treated as “gastrik.”

What causes gastritis?

H. pylori infection

H. pylori is a bacterium that can live in the stomach lining. It is a common cause of chronic gastritis and may also contribute to peptic ulcers. Long-standing untreated infection can increase the risk of stomach cancer in some people.

Certain medicines

Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, aspirin and diclofenac can irritate and injure the stomach lining. Do not stop prescribed medicines without speaking to your doctor.

Alcohol and other irritants

Heavy alcohol use, smoking and bile reflux can irritate the stomach lining and contribute to inflammation.

Autoimmune and other causes

In autoimmune gastritis, the immune system attacks cells in the stomach lining. Other causes include some infections, Crohn’s disease and severe physical stress on the body.

Does stress cause gastritis?

Everyday emotional stress can make stomach discomfort feel worse, but it should not automatically be assumed to be the cause of inflammation. “Stress gastritis” is also a medical term used for stomach injury associated with severe physical illness, such as critical illness or major trauma.

How is gastritis diagnosed?

Your doctor will ask about your symptoms, medical history, medicines and possible risk factors. Depending on the findings, investigations may include:

H. pylori breath or stool testChecks for an active infection.
Blood testsMay identify anaemia or nutritional deficiencies and help investigate other causes.
Gastroscopy (upper endoscopy)A thin flexible camera examines the oesophagus, stomach and first part of the small intestine. Small tissue samples (biopsies) may be taken when appropriate.
Not everyone with mild indigestion needs a gastroscopy.

When to seek help

Vomiting blood, black tarry stools or sudden severe pain require emergency attention.

Persistent or recurring discomfort should be assessed rather than repeatedly self-treated as “gastrik.”

Frequently asked questions

Does everyone with gastritis need an endoscopy?

No. A doctor may start with a history, examination and non-invasive tests. Gastroscopy is considered when symptoms, warning signs or other risk factors justify a closer examination.
