What is Gastritis?

Gastritis is inflammation of the stomach lining (gastric mucosa). It may develop suddenly (acute gastritis) or persist longer (chronic gastritis). Gastritis and gastropathy are related but different: gastritis involves inflammation, while gastropathy refers to damage to the stomach lining with little or no inflammation.

What is the Importance of Timely Treatment?

Timely diagnosis and treatment can help relieve symptoms and prevent complications. Persistent H. pylori infection can contribute to peptic ulcers, atrophic gastritis and an increased risk of certain stomach cancers. Some forms of gastritis, particularly autoimmune gastritis, may also interfere with iron and vitamin B12 absorption and contribute to anemia. Gastritis that causes bleeding requires prompt medical evaluation. Warning signs include black or tarry stools, blood in the stool, vomiting blood or vomit that resembles coffee grounds, dizziness, and unusual weakness.

What are the Common Symptoms of Gastritis?

  • Upper abdominal pain, discomfort or burning
  • Nausea or vomiting
  • Feeling full soon after starting a meal
  • Uncomfortable fullness after eating
  • Loss of appetite
  • Indigestion
  • Unintentional weight loss in some cases
  • Gastrointestinal bleeding in more severe cases

Causes and Risk Factors of Gastritis

Causes

  • H. pylori infection: A major cause of chronic gastritis.
  • NSAID use: Long-term use of medicines can damage the stomach lining.
  • Alcohol: Excessive alcohol consumption can irritate and damage the stomach lining.
  • Autoimmune gastritis: The immune system attacks cells in the stomach lining.
  • Bile reflux: Bile flowing back into the stomach can irritate the gastric lining.
  • Severe physical stress: Critical illness, severe burns, major injuries or sepsis can contribute to stress-related erosive gastropathy.
  • Certain treatments: Chemotherapy and radiation therapy may sometimes affect the stomach lining.
  • Other diseases: Conditions such as Crohn's disease and certain infections can occasionally be associated with gastritis or gastropathy.

Risk Factors

Latest Research and Technologies in the Treatment of Gastritis in Thailand

  • Current gastritis management focuses on identifying the underlying cause and selecting treatment accordingly. H. pylori infection is treated with an appropriate combination of antibiotics and acid suppression, with the regimen guided by previous antibiotic exposure and resistance patterns where possible. Proton pump inhibitors (PPIs) remain the most common choice for acid suppression, while potassium-competitive acid blockers (P-CABs) are an alternative in appropriate clinical settings. Endoscopy with biopsy may be recommended for selected patients to assess persistent symptoms, investigate warning signs, or identify atrophic gastritis and other abnormalities.

Treatment options for Gastritis

Upper Gastrointestinal (UGI) endoscopy : It is also known as an esophagogastroduodenoscopy (EGD) and is the gold standard procedure for evaluating, diagnosing, and managing gastritis. While a clinical history can suggest stomach inflammation, a UGI endoscopy lets a gastroenterologist directly visualise the stomach lining and collect tissue samples for confirmation.


Cost Start From 700Explore Options

  • Clinical assessment:
    • Medical History and Symptom Review: The doctor evaluates abdominal pain, nausea, vomiting, indigestion, appetite changes, and other symptoms, along with their duration and severity.
    • Physical Examination: The physician may examine the abdomen for tenderness, discomfort, or other signs that could indicate gastritis or another digestive condition.
    • H. pylori Stool Antigen Test: This test detects H. pylori proteins in a stool sample and can help diagnose active infection.
    • Urea Breath Test: The patient drinks a urea-containing solution, and the test detects substances produced when H. pylori breaks down urea in the stomach.
    • Blood Tests: Blood tests may help identify anemia, iron deficiency, vitamin B12 deficiency, or other abnormalities associated with certain types of gastritis.
  • Medicines used for gastritis generally focus on reducing stomach irritation, controlling symptoms, and supporting healing. Treatment varies by cause and may include acid-reducing medicines, infection-treating medications, or nutritional supplements when deficiencies are present. Treatment choice depends on the individual's symptoms, medical history, and overall condition.

Frequently Asked Questions

Recovery depends on the type and cause of gastritis. Symptoms from temporary irritation may improve relatively quickly after you remove the trigger and start treatment. H. pylori gastritis requires a complete eradication regimen followed by testing to confirm that the infection has been cleared. Chronic or autoimmune gastritis may require longer-term monitoring and management.

Yes. Gastritis generally does not prevent normal walking or physical activity. However, people experiencing significant abdominal discomfort, vomiting, weakness, dizziness or bleeding should rest and seek medical advice. Severe dizziness, weakness or signs of gastrointestinal bleeding require prompt medical attention.

Many Thai hospitals have gastroenterology departments equipped for diagnostic endoscopy, biopsy, pathology, H. pylori testing and management of gastrointestinal bleeding. Some centres may also have advanced endoscopic imaging and emerging AI-assisted endoscopy technologies. Availability varies between hospitals.

Many hospitals and medical centres in Thailand have dedicated international-patient services. Depending on the provider, these may include medical record coordination, appointments, interpreter assistance, airport transfers, accommodation support and assistance with treatment-related logistics.

Consider the gastroenterologist's experience with your specific condition, the hospital's gastroenterology and endoscopy facilities, availability of pathology and H. pylori testing, multidisciplinary support and experience treating international patients. For complex or recurrent gastritis, reviewing previous endoscopy, biopsy and treatment records with a gastroenterologist can help determine the appropriate next step.

There is no single success rate for gastritis treatment in Thailand because gastritis includes several conditions with different causes and treatment responses. Outcomes depend on whether the condition is related to H. pylori, medicines, autoimmune disease, alcohol, bile reflux or another cause.

Thailand has gastroenterologists who diagnose and manage gastritis, H. pylori infection, peptic ulcers, gastrointestinal bleeding and other digestive disorders. When choosing a specialist, patients should review relevant qualifications, gastroenterology experience, endoscopy expertise and the hospital's available diagnostic facilities.

Risks depend on the treatment used. Antibiotics can cause side effects such as nausea, diarrhea or allergic reactions. Acid-suppressing medicines may have potential adverse effects, particularly with prolonged use. Endoscopy is generally safe but can carry risks such as bleeding, infection or reactions to sedation.

Seek urgent medical attention if you vomit blood, vomit material resembling coffee grounds, pass black tarry stools, experience fainting, or develop sudden, severe abdominal pain. These symptoms may indicate bleeding or another serious condition. Persistent vomiting, unexplained weight loss, or difficulty swallowing also warrants prompt medical assessment.

Most cases do not cause permanent damage when doctors treat the underlying cause appropriately. However, chronic atrophic gastritis can change the stomach lining and impair absorption of iron or vitamin B12. Some forms, particularly those linked to persistent H. pylori infection or autoimmune gastritis, increase the risk of certain gastric complications and may require follow-up.

Yes. Abdominal discomfort, burning, nausea, indigestion, early fullness, and appetite changes can interfere with eating, sleep, work, and daily activities. Persistent symptoms may also cause anxiety about food or possible complications.

The consequences depend on the type of gastritis. Persistent H. pylori infection can contribute to peptic ulcers, atrophic gastritis, and an increased risk of gastric cancer. Erosive gastritis may cause gastrointestinal bleeding, while autoimmune gastritis can lead to iron or vitamin B12 deficiency. Not every case progresses to complications, but persistent or worsening symptoms should be evaluated.

Prevention depends on the underlying cause. Measures may include testing for and treating H. pylori when indicated, avoiding unnecessary NSAID use, limiting alcohol, and stopping smoking. If you require long-term NSAIDs, discuss stomach protection with your doctor rather than stopping prescribed medication yourself.

Yes. H. pylori gastritis is more common in some populations and geographic regions. NSAID-related stomach-lining damage is more likely in people who regularly use these medicines, particularly older adults and those with a history of ulcers. Autoimmune gastritis is more common among people with certain autoimmune conditions.
