Understanding Gastritis
Gastritis describes inflammation of the stomach lining.
The stomach lining normally protects deeper tissue from stomach acid, digestive enzymes and other irritants. Gastritis occurs when this lining becomes inflamed.
Some people with gastritis have no symptoms. Others experience upper-abdominal discomfort, nausea, early fullness, reduced appetite or vomiting. These symptoms can also occur with ulcers, indigestion, reflux, gallbladder disease and other conditions.
At Apgujeong Hana Clinic, we assess possible causes such as Helicobacter pylori infection, anti-inflammatory pain medicines, alcohol exposure, immune conditions and previous stomach disease before planning treatment.
🔥
Acute Gastritis
Inflammation may begin suddenly after illness, medicine exposure, alcohol or another stomach injury.
📅
Chronic Gastritis
Long-standing inflammation may develop gradually and can be related to H. pylori or immune conditions.
🦠
H. pylori Gastritis
H. pylori is a common bacterial cause of chronic stomach-lining inflammation.
💊
Reactive Gastropathy
The stomach lining may be damaged by medicines or chemical irritation with limited inflammation.
Possible Symptoms
Gastritis symptoms can overlap with several stomach conditions.
Many people have no obvious symptoms. When symptoms occur, their pattern and associated warning signs help determine whether testing or gastroscopy is appropriate.
Upper-Abdominal Pain
Burning, aching or discomfort in the upper or central abdomen.
Nausea
Recurring nausea, queasiness or discomfort that may become worse around meals.
Early Fullness
Feeling full soon after beginning a meal or after eating a small amount.
Fullness After Meals
Remaining uncomfortably full, bloated or heavy after eating.
Loss of Appetite
Reduced interest in food or avoiding meals because eating produces discomfort.
Vomiting
Repeated vomiting or vomiting associated with pain, dehydration or blood requires medical attention.
Unexplained Weight Loss
Weight loss related to reduced appetite, pain or persistent symptoms needs evaluation.
Digestive Bleeding
Black stool, vomiting blood or anaemia may occur when the stomach lining bleeds.
Abnormal Gastroscopy
Gastritis noted on a previous endoscopy or biopsy may require cause-specific follow-up.
Causes & Risk Factors
Treatment depends on what is affecting the stomach lining.
🦠
Helicobacter pylori
H. pylori infection is a major cause of chronic gastritis and is also associated with peptic ulcers.
💊
NSAID Pain Medicines
Aspirin, ibuprofen, naproxen and related medicines may damage the stomach lining, particularly with frequent use.
🍷
Alcohol Irritation
Heavy or repeated alcohol exposure can irritate and damage the stomach lining.
🛡️
Autoimmune Gastritis
The immune system may attack stomach cells, potentially affecting vitamin B12 absorption and causing anaemia.
🏥
Severe Physical Stress
Critical illness, major burns, severe injury or surgery can cause stress-related stomach-lining damage.
🔄
Bile Reflux
Bile flowing backward into the stomach may contribute to chemical irritation in selected patients.
🌾
Other Medical Conditions
Selected infections, inflammatory conditions, food allergies or celiac disease may affect the stomach lining.
🧪
Previous Stomach Surgery
Surgery may change stomach anatomy and increase exposure to bile or other irritants.
❓
Unclear Cause
In some patients, the cause remains uncertain even after clinical assessment and testing.
Gastritis is not simply “too much stomach acid”
Gastritis refers to inflammation of the stomach lining. Acid may worsen irritation or symptoms, but treatment should also identify infection, medicine-related injury, immune disease or another underlying cause.
Gastritis Evaluation
Symptoms alone cannot always confirm stomach inflammation.
🗂️
Medical History
We review pain, nausea, meals, bleeding, medicines, alcohol, previous H. pylori treatment and endoscopy results.
🩸
Blood Tests
Blood count, iron, vitamin B12 or other tests may help identify anaemia or related conditions.
🫁
Breath Testing
A urea breath test may be used to detect active H. pylori infection when preparation requirements are followed.
🧫
Stool Testing
A stool antigen test may help detect active H. pylori infection or confirm eradication after treatment.
📹
Gastroscopy
Direct examination may identify inflammation, erosions, ulcers, bleeding or another upper-digestive condition.
🔬
Stomach Biopsy
Tissue samples may determine the type of gastritis, detect H. pylori and assess selected complications.
Indigestion does not always mean gastritis
Upper-abdominal pain, early fullness and nausea can occur with functional dyspepsia, ulcers, reflux, gallbladder disease, gastroparesis and other conditions. Testing is chosen according to the complete pattern.
H. pylori & Gastritis
Active H. pylori infection requires treatment and follow-up confirmation.
🦠
H. pylori can remain in the stomach for years without obvious symptoms.
When infection is confirmed, treatment usually combines acid suppression with antibiotics or another recommended eradication regimen.
Active-Infection Testing
Breath, stool or biopsy testing may be used to determine whether active infection is present.
Medicine Preparation
Proton pump inhibitors, antibiotics and bismuth can affect test accuracy and may need temporary adjustment under medical guidance.
Combination Treatment
H. pylori is treated using a complete multi-medicine regimen selected according to clinical factors.
Complete Every Dose
Missing medicines may reduce the chance of eradication and contribute to antibiotic resistance.
Test of Cure
Follow-up breath or stool testing is generally used to confirm that infection has been eradicated.
Persistent Infection
When treatment fails, the next regimen should consider medicines already used and possible resistance.
Symptom improvement does not prove that H. pylori has been eradicated
Symptoms may improve even when infection remains. A properly timed test of cure is important after treatment rather than relying only on how the stomach feels.
Personalised Treatment
Gastritis treatment follows the cause and severity.
🦠
H. pylori Eradication
Confirmed infection is treated with a complete combination regimen and follow-up testing.
💊
Acid Suppression
Proton pump inhibitors or other medicines may reduce irritation and support healing.
🩹
Lining Protection
Selected medicines may help protect the stomach lining depending on the cause and findings.
🔁
NSAID Review
Pain medicines are reviewed for necessity, dose, alternatives and stomach-protection needs.
🍷
Irritant Reduction
Alcohol and other personal irritants may need reduction when they clearly worsen symptoms or lining injury.
🩸
Anaemia Treatment
Iron or vitamin B12 deficiency is investigated and treated when related to chronic gastritis.
📹
Endoscopy-Guided Care
Treatment and follow-up may change when gastroscopy identifies erosions, ulcers or other findings.
📅
Follow-Up Planning
Persistent symptoms, biopsy findings, H. pylori status and medicine response are reviewed over time.
Food & Gastritis
Diet may affect symptoms—but does not cause most gastritis.
Food choices can influence comfort during recovery, but broad restriction does not replace treatment of infection, medicine-related injury or another underlying cause.
Spicy Food
Spicy food may worsen burning or discomfort in some patients but is not the main cause of most gastritis.
Personal Trigger
Coffee & Caffeine
Coffee may increase symptoms in some people. Avoidance is most useful when there is a consistent personal connection.
Symptom Based
Alcohol
Alcohol can irritate the stomach lining and may need to be reduced or avoided during treatment.
Lining Irritant
Meal Size
Smaller meals may be easier to tolerate when early fullness, nausea or post-meal discomfort is present.
Comfort Strategy
Extreme Restriction
Avoiding many foods without a clear reason can reduce nutrition and may not address the cause of symptoms.
Avoid Overrestriction
Seek Prompt Medical Care
Some symptoms may indicate bleeding or another serious condition.
🩸
Vomiting Blood
Red blood or vomit resembling coffee grounds may indicate upper-digestive bleeding.
⬛
Black Tarry Stool
Black, sticky stool may be a sign of bleeding from the stomach or upper digestive tract.
⚠️
Sudden Severe Pain
Sharp, intense or rapidly worsening abdominal pain should not wait for a routine appointment.
🤮
Persistent Vomiting
Repeated vomiting or inability to keep fluids down can cause dehydration and requires assessment.
😵
Weakness or Fainting
Severe weakness, dizziness or fainting may indicate blood loss, dehydration or another urgent problem.
📉
Progressive Weight Loss
Unexplained weight loss with pain, vomiting, reduced appetite or anaemia needs evaluation.

FAQ
Gastritis questions, answered.
Bring previous gastroscopy, biopsy, H. pylori and blood-test reports plus a complete medication and supplement list.
No. Gastritis involves inflammation of the stomach lining. Acid reflux occurs when stomach contents move upward into the esophagus. The symptoms may overlap, but the conditions affect different areas.
No. Gastritis is inflammation of the stomach lining, while an ulcer is a deeper open sore in the stomach or duodenal lining. H. pylori and NSAID medicines can contribute to both conditions.
Not every patient needs immediate gastroscopy. It may be recommended when symptoms persist, bleeding or anaemia is present, weight loss occurs, the diagnosis is uncertain or a biopsy is needed.
Yes. H. pylori is a common cause of chronic gastritis. When active infection is confirmed, eradication treatment and a properly timed test of cure are generally recommended.
Aspirin and NSAID pain medicines such as ibuprofen and naproxen can damage the stomach lining. Do not stop prescribed medicine without discussing the risks, benefits and possible alternatives with your doctor.
Spicy food may worsen discomfort in some patients but does not cause most cases of gastritis. H. pylori, medicines, alcohol, immune conditions and other causes should be considered.
Yes. Bring the complete procedure report, photographs, pathology or biopsy results and records of previous H. pylori treatment.
