What is happening inside your stomach
Gastritis simply means the lining of your stomach has become irritated and inflamed. That lining normally protects the wall of your stomach from its own powerful acid, so when the barrier is disturbed, even a small amount of acid can cause a raw, burning discomfort. On holiday the triggers are usually easy to spot: a run of late nights, spicy street food, more alcohol than usual, painkillers taken on an empty stomach, or the stress of travel itself. Sometimes a bacterium called Helicobacter pylori is the hidden culprit, quietly inflaming the lining for months before symptoms finally flare. It is one of the most common reasons a happy holiday appetite suddenly disappears, and the good news is that it usually responds well once the cause is identified and the right treatment is started.
Signs that point to an irritated stomach
Most travellers describe a gnawing or burning ache high in the belly, just below the breastbone. It may ease briefly after eating and then return, or worsen when the stomach is empty overnight. Look out for:
- A burning or gnawing pain in the upper abdomen
- Feeling uncomfortably full or bloated soon after starting a meal
- Nausea, occasional retching, or loss of appetite
- Frequent belching, an acidic taste, or heartburn rising into the chest
- Queasiness that is worse with coffee, alcohol, or greasy food
These symptoms overlap with acid reflux and with the stomach upset of a bug picked up from food or water, which is why a doctor’s assessment is worth the short trip in.
How we sort it out and settle it
Your visit starts with a proper conversation about what you have eaten, drunk, and taken recently, followed by an examination of your abdomen. Where it helps, we can arrange a simple blood test or a stool test for H. pylori through our on-site lab, with results the same day. Treatment usually combines an acid-reducing medicine such as a proton-pump inhibitor to give the lining time to heal, something to ease nausea, and clear advice on what to avoid. If H. pylori is confirmed we prescribe a short, targeted course of antibiotics. When vomiting has left you dehydrated, an IV drip can rehydrate you and quiet the nausea quickly so you can get back to your trip.
When stomach pain is an emergency
Ordinary gastritis is uncomfortable but not dangerous. Certain signs, though, mean you should go straight to a hospital emergency department rather than wait. Seek urgent care if you notice black, tarry stools or vomit that looks like coffee grounds or contains blood; sudden, severe, or rigid abdominal pain; repeated vomiting that stops you keeping any fluids down; a racing heart, dizziness, or fainting; or pain spreading to your chest, arm, or jaw. These can signal bleeding, an ulcer, or a problem that only a hospital with a scope and imaging can manage. If you are unsure, call us first on +66 83 150 2520 and a doctor will help you decide.
Everyday steps that speed recovery
Alongside medication, small changes make a real difference. Eat lighter, more frequent meals rather than one large one, and pause the chilli, coffee, fizzy drinks, and alcohol until the burning settles. Bland, easy foods such as rice, bananas, toast, and clear soups are gentle while the lining recovers. Avoid ibuprofen and aspirin, which irritate the lining, and reach for paracetamol instead if you need pain relief. Sit upright for an hour or so after eating rather than lying down, drink water steadily through the day, and give yourself a couple of quieter days out of the sun. Most flare-ups ease within a few days once the trigger is removed and treatment begins, and if yours does not improve as expected we would rather see you again than have you struggle on.
Costs, insurance and reaching us
We keep pricing transparent: you receive a full receipt and a medical report, and we bill most travel insurers directly so you are not left out of pocket. A doctor is on call 24 hours, and if you feel too unwell to travel we offer hotel and villa visits across the island, from Chaweng to Bophut. Walk in during the day, phone us on +66 83 150 2520, or message us on WhatsApp and we will guide you from there.
Frequently asked questions
Can I keep drinking coffee or alcohol while my stomach heals?
It is best to pause both until the burning has settled for a few days. Coffee, alcohol, and fizzy drinks all increase stomach acid and irritate the raw lining, which slows healing and prolongs the discomfort. Once you feel well, reintroduce them slowly and in smaller amounts.
Which painkillers are safe if I have gastritis?
Avoid ibuprofen, aspirin, and similar anti-inflammatory tablets, as they directly irritate the stomach lining and can make gastritis worse or trigger bleeding. Paracetamol is gentler on the stomach and is usually the safer choice. Ask our doctor if you take regular medication.
Do I need to fast before coming in to see you?
No. You can walk in and be seen straight away without fasting. If we decide a specific blood or stool test would help, our team will tell you on the day whether any preparation is needed, but most assessments and treatments require none.
Is gastritis contagious to my travel companions?
The inflammation itself is not passed person to person. However, the H. pylori bacterium that can cause it may spread through shared food, utensils, or close contact, so good hand hygiene is sensible if a test confirms it. A stomach bug from contaminated food is a separate issue.
Could my usual reflux medication just be failing on holiday?
Quite possibly. Travel, richer food, more alcohol, and missed doses can all overwhelm a regular reflux regimen. We can review what you take, adjust the dose, and rule out a fresh flare of gastritis or an ulcer so you are not simply guessing while away from your own doctor.
How soon can I fly home if gastritis started before my flight?
Most people fly comfortably once the pain and nausea are controlled, which is often within a day or two of starting treatment. We can assess you, provide medication for the journey, and issue a medical report or fit-to-fly note if your airline or insurer requests one.
Will you give me a report for my insurance claim?
Yes. Every visit comes with an itemised receipt and a written medical report detailing the diagnosis and treatment, which is what most travel insurers require. We also bill many insurers directly, so in many cases you will not need to pay upfront and claim later.
What if my symptoms come back after I finish treatment?
If the burning returns once medication ends, it may mean an underlying cause such as H. pylori or an ulcer needs addressing. Come back in and we will reassess, arrange any further testing through our lab, and, if appropriate, refer you for a scope at a hospital.
