A bout of diarrhea is one of the most common reasons travellers visit our walk-in clinic in Koh Samui. New foods, street-stall meals, ice in drinks, spicy curries, and the tropical heat can all upset a holiday stomach within a day or two of arriving. Whether you are staying in Chaweng, Lamai, Bophut or Maenam, our English-speaking doctors can assess you quickly, get you rehydrated, and help you get back to enjoying the island.
What is traveler’s diarrhea?
Traveler’s diarrhea means passing three or more loose, watery stools in 24 hours, usually after eating or drinking something your body is not used to. In Koh Samui it is most often caused by bacteria (such as E. coli), and sometimes by viruses or parasites, picked up from contaminated food or water. “Food poisoning” is a closely related term for the rapid stomach upset that follows a contaminated meal. Most cases are unpleasant but short-lived, settling within a few days — the main risk is dehydration, especially in the island heat.
Symptoms to Watch For
– Loose, watery or frequent stools
– Stomach cramps and bloating
– Nausea or vomiting
– Urgency or a feeling of incomplete emptying
– Low-grade fever in some cases
– Signs of dehydration: thirst, dark urine, dizziness, dry mouth, tiredness
Causes & Risk Factors
Common triggers on the island include undercooked seafood, unwashed salads or fruit, ice and tap water, dairy left in the heat, and simply a sudden change in diet. Drinking alcohol, the heat, and a long day of activities can make dehydration worse. Young children, older travellers, and anyone with a weakened immune system are more likely to become dehydrated and should be seen sooner rather than later.
How We Diagnose It
Diagnosis is usually clinical — our doctor asks about your symptoms, recent meals, travel and hydration, then examines your abdomen and checks for signs of dehydration. Most cases need no tests. If your diarrhea is prolonged, bloody, or comes with a high fever, we may arrange a stool test to look for bacteria or parasites so treatment can be targeted. If you also have a high temperature, our fever assessment in Koh Samui may be carried out at the same visit.
How We Treat It
The most important treatment is rehydration. For mild cases we recommend oral rehydration salts, plenty of fluids, and a gentle diet. For moderate to severe dehydration — or if you cannot keep fluids down because of vomiting — we offer IV drip rehydration in Koh Samui, which restores fluids and salts quickly so you feel better faster. We may also provide anti-nausea medication, and where appropriate, anti-diarrheal medicine. Antibiotics are not needed for most cases; we reserve them for clearly bacterial infections, bloody diarrhea, or severe symptoms, and we always prescribe responsibly after assessing you in person. Probiotics may help settle the gut during recovery.
Recovery & Aftercare
Most travellers improve within 2–4 days. Keep sipping fluids and rehydration salts, ease back onto plain foods (rice, toast, bananas, soup), and avoid alcohol, very spicy food and heavy dairy until your stomach settles. Wash hands well and be careful with food and water for the rest of your trip. Return to see us — or message us on WhatsApp — if symptoms are not improving after a few days, if you cannot stay hydrated, or if new symptoms appear.
When to Seek Urgent Care
Seek care promptly if you have:
– Blood or mucus in your stools
– A high fever
– Severe or constant abdominal pain
– Persistent vomiting and inability to keep fluids down
– Signs of significant dehydration (very little urine, dizziness, confusion, rapid heartbeat)
– Diarrhea lasting more than a few days, or symptoms in a baby, young child or elderly traveller

FAQ for Tourists
- Q: Is it safe to take anti-diarrheal medicine?
A: For ordinary watery traveller’s diarrhea it can help, but it should be avoided if you have a high fever or bloody stools. It is best to check with our doctor first, especially before a flight.
- Q: Can I get IV fluids at my hotel?
A: Yes. We provide hotel- and villa-based IV rehydration across Koh Samui, which is ideal if vomiting is keeping you from drinking enough.
- Q: Do I need antibiotics for diarrhea?
A: Usually not. Most cases settle with rehydration alone. Antibiotics are only used for clearly bacterial infections or severe symptoms, after a doctor assesses you.
- Q: How long does traveller’s diarrhea last?
A: Most cases improve within 2–4 days. If it lasts longer, becomes bloody, or you cannot stay hydrated, please come in for assessment.
- Q: How can I avoid getting it again on my trip?
A: Drink bottled or filtered water, be cautious with ice, peel fruit, choose freshly cooked hot food, and wash your hands often. These simple steps prevent most repeat episodes.
- Q: Will it delay my travel or flight?
A: Most cases resolve quickly with treatment, and fit-to-fly checks and doctor’s notes are available if you need them for your airline or insurer.
