A tummy bug can hit fast. One minute your child is splashing in the hotel pool, the next they are running to the bathroom or being sick. It is one of the most common problems we see in visiting kids in Krabi. The bug itself usually passes in a few days. The real worry is dehydration, which comes from losing fluid faster than a child takes it in.
The good news is that most tummy bugs can be handled right at your hotel with the correct fluids. This guide shows you rehydration that actually works, what to feed, what to avoid, and the signs that mean your child needs a doctor in Ao Nang.
Why Fluids Matter More Than Food
When a child has diarrhea or is vomiting, they lose water and salts the body needs. Replacing them is the whole game. Food can wait a day, but fluids cannot. The best fluid is an oral rehydration solution, made from sachets you mix with clean water. It has the right balance of salt and sugar to pull water back into the body. Plain water alone does not replace lost salts, and sugary sodas or juice can pull more water into the gut and make diarrhea worse.
The trick is small and often. A big glass gulped down may come straight back up. Instead, give a spoonful or a small sip every few minutes. After each loose stool or each vomit, offer a little more. A young child needs less at a time but more often. If your child is breastfeeding, keep feeding, and add rehydration solution between feeds. Slow and steady wins over a tummy bug.
What to Give and What to Skip
Reach for oral rehydration solution first. If you did not pack sachets, our clinic and local pharmacies in Ao Nang have them. Once your child stops vomiting and wants to eat, start with plain, easy foods like rice, bananas, toast, or crackers. Let their appetite lead, and do not force a full meal. Keep offering the rehydration drink alongside food until the diarrhea settles. Little amounts of familiar food often go down best.
Skip sugary sodas, energy drinks, and undiluted fruit juice, since the sugar can worsen diarrhea. Avoid very fatty or spicy foods for a day or two. Do not give anti-diarrhea medicines made for adults to young children unless a doctor says so, as they can be harmful. If you are unsure what is safe for your child’s age, ask our doctor or a pharmacist rather than guessing.
Dehydration Signs and When to See a Doctor in Ao Nang
Watch for signs that your child is drying out. These include fewer wet nappies or trips to the toilet, dark urine, a dry mouth and tongue, no tears when crying, sunken eyes, and unusual sleepiness or crankiness. In babies, a sunken soft spot on the head is a warning. If your child cannot keep any fluid down, has these signs, or seems to be getting worse, they need a doctor the same day.
Also see a doctor if there is blood in the stool, a high fever, bad tummy pain, or vomiting that will not stop, or if a tummy bug drags on past a few days. Very young babies get dehydrated fast, so do not wait with them. At our Ao Nang clinic we check how dehydrated your child is, and if needed we can give fluids and treatment. We can also visit your hotel if travel is hard.

Frequently Asked Questions
How do I know if my child is dehydrated?
Look for fewer wet nappies or toilet trips, dark urine, a dry mouth, no tears when crying, sunken eyes, and low energy. In babies, watch the soft spot on the head. A well-hydrated child stays alert and keeps weeing. If you spot several of these signs in Ao Nang, offer more rehydration solution and see our doctor the same day.
Can I just give my child water instead of rehydration salts?
Plain water helps a little, but it does not replace the salts lost through diarrhea and vomiting, and too much plain water can upset the balance further. Oral rehydration solution has the right mix of salt and sugar to pull water back into the body. If you have no sachets, pharmacies in Ao Nang stock them. It is worth using the proper solution.
My child keeps vomiting up the fluids. What can I do?
Slow right down. Give just a few drops or a tiny sip every couple of minutes, even if it feels too little. Big amounts trigger more vomiting, while tiny sips often stay down. Wait ten minutes after a vomit, then start the small sips again. If your child cannot keep anything down for several hours, see our doctor, as they may need fluids.
How long should a kids’ tummy bug last?
Most tummy bugs in children ease within two to four days, with diarrhea sometimes lingering a little longer. The key is keeping fluids up the whole time. If it lasts more than a few days, there is blood in the stool, or your child is getting worse rather than better, have our Ao Nang doctor take a look to find the cause.
When does a tummy bug need a hotel visit or clinic in Ao Nang?
See a doctor or ask for a hotel visit if your child cannot keep fluids down, shows dehydration signs, has blood in the stool, a high fever, or bad tummy pain. Babies and toddlers need care sooner, since they dry out fast. Our doctor can come to your hotel across Ao Nang and Krabi to check and treat your child the same day.
