Gastritis treatment in Koh Samui
A burning, gnawing pain in the upper stomach can wreck a holiday fast. Our English-speaking doctors find out why your stomach lining is inflamed and calm it with the right acid-control treatment.
What gastritis is
Gastritis is inflammation of the stomach lining. When that lining is irritated, the balance between protective mucus and stomach acid tips, and the acid begins to sting the raw surface, which is what you feel as burning upper-abdominal pain. Acute gastritis flares suddenly and usually settles within a few days once the irritation is controlled. Chronic gastritis simmers over weeks or months and is more often linked to a Helicobacter pylori infection or long-term use of anti-inflammatory painkillers.
Koh Samui serves up plenty of triggers. Spicy street food, one too many cocktails, strong coffee on an empty stomach, painkillers grabbed for a hangover or sunburn, skipped meals and the general stress of travel all irritate the digestive tract and set gastritis off.
Symptoms to recognise
Gastritis usually shows up as a group of symptoms rather than a single one. Watch for:
- Burning or gnawing pain in the upper abdomen, often worse when hungry or late at night
- Nausea, bloating, belching and a sour taste, especially after eating
- Feeling full quickly, a reduced appetite and mild indigestion
- Symptoms that ease briefly after food or antacids, then return
Most gastritis is uncomfortable rather than dangerous, but it can mimic more serious problems, so a quick check with a doctor is wiser than guessing at the pharmacy counter.
How our doctors assess and treat you
At the clinic a doctor takes a focused history, examines your abdomen, and asks about recent food, alcohol and medication. Because we have an on-site laboratory, we can run a same-visit blood test or check for H. pylori when the picture suggests a bacterial cause. Identifying the trigger is what turns short-term relief into a proper recovery.
Treatment usually centres on medicines that reduce stomach acid and let the lining heal, together with clear, practical advice on what to eat, drink and avoid while your stomach settles. If H. pylori is found, we treat it directly. Our on-site pharmacy means you leave with everything in hand, and if you are too unwell to travel we make hotel and villa visits island-wide.
Red flags: when to go to hospital
A few symptoms point to bleeding or a more serious problem and need emergency hospital care immediately rather than a clinic visit. Go straight to a hospital if you have any of these:
- Vomiting blood, or vomit that looks like coffee grounds
- Black, tarry or bloody stools
- Severe, sudden or spreading abdominal pain, or persistent vomiting and dehydration
- Chest pain or pain spreading to the arm or jaw, which can be mistaken for indigestion
If you are unsure, call us and a doctor will advise whether to come in or head straight to hospital.

Frequently Asked Questions
What usually causes gastritis on holiday?
Common triggers include spicy food, alcohol, strong coffee on an empty stomach, painkillers taken for a hangover or sunburn, skipped meals and stress. A Helicobacter pylori infection is a frequent cause of longer-lasting gastritis, which our doctor can test for.
How long does gastritis take to settle?
Acute gastritis often eases within a few days once the acid and irritation are controlled and the trigger is removed. If your symptoms keep returning over weeks, come in so we can look for an underlying cause such as H. pylori.
Do you test for H. pylori?
Yes. Our on-site laboratory can screen for Helicobacter pylori, a common bacterial cause of gastritis, when your history suggests it. If it is present, we can treat it directly to help the stomach lining heal.
What should I eat while my stomach settles?
Smaller, plainer meals, plenty of water, and avoiding alcohol, strong coffee, very spicy food and anti-inflammatory painkillers all give the lining a chance to recover. The doctor will give you clear, practical advice tailored to your symptoms.
Could my stomach pain be something more serious?
Gastritis can mimic other conditions, which is why a quick assessment is worthwhile. Vomiting blood, black or tarry stools, severe or spreading pain, or chest pain are red flags that need emergency hospital care rather than a clinic visit.
Is it gastritis or a stomach bug?
Gastritis centres on burning upper-stomach pain, while a stomach bug usually brings watery stools and cramping lower down. Our doctor sorts one from the other and treats accordingly, since the two are managed quite differently.
Can you come to my hotel or villa?
Yes. We make visits to accommodation across Chaweng, Bang Rak and Bophut and island-wide. A doctor can assess your abdomen, arrange any testing and start treatment without you having to travel while in pain.
Will my travel insurance cover the visit?
We offer direct billing with most travel insurers, so in many cases there is no large bill to pay upfront and claim back later. Bring your policy details and passport and our team will handle the paperwork.
