Picture this: you’ve finally made it to the Gili Islands. The sun is kissing your skin, the water is a dazzling turquoise, the sand is powder-soft between your toes, and a freshly cracked coconut is on its way. It’s absolute paradise. But then… your stomach starts to rumble for all the wrong reasons. A dicky tummy, often dubbed ‘Bali Belly’, is the one uninvited guest that can turn your dream holiday into a bathroom-bound nightmare.
The Gilis Trawangan, Meno, and Air are a slice of heaven on earth, a must-visit for their vibrant reefs, epic sunsets, and car-free, laid-back charm. The last thing you want is for your memories to be tainted by nausea and cramps.
But don’t you worry! I’m here to be your guide on the side, ensuring your only Gili memories are of swinging in a hammock and swimming with turtles. This guide is packed with 7 practical, no-nonsense tips to help you avoid a tummy bug on your Gili holiday, so you can soak up every single drop of that tropical bliss.
First Things First: What Exactly is a Tummy Bug, a.k.a. ‘Bali Belly’?
Before we dive into prevention, let’s get acquainted with the enemy. Knowing what you’re up against is half the battle won.
It’s More Than Just an Upset Stomach
‘Bali Belly’ is the catchy, alliterative name for a rather unpleasant bout of traveller’s diarrhoea. It’s an incredibly common digestive issue that can catch travellers off guard when they visit new climes, especially in tropical destinations like Indonesia. Your gut is used to the bacteria in your home environment, and when it encounters a new crew of microorganisms, it can sometimes react… poorly.
The common culprits behind this holiday-ruining affliction are usually:
- Bacteria: Nasty critters like E. coli, Salmonella, and Campylobacter are the most frequent offenders. They love to hitch a ride on contaminated food or in untreated water.
- Viruses: The notorious norovirus can also be a cause, spreading easily from person to person.
- Parasites: Less common, but still a possibility, are parasites like Giardia.
These tiny troublemakers typically lead to a cascade of rather grim symptoms. Understanding what causes a Gili Islands tummy bug is your first and most powerful step toward preventing one.
Quote: “An ounce of prevention is worth a pound of cure.” – Benjamin Franklin. This has never been more true than when you’re trying to protect your holiday!
Common Symptoms of Bali Belly:
- Sudden onset of diarrhoea
- Stomach cramps and bloating
- Nausea and/or vomiting
- General feeling of being unwell (malaise)
- Sometimes a low-grade fever
Tip 1: Be Wise with Water to Sidestep a Stomach Bug
If you remember only one thing from this guide, let it be this: be incredibly careful with the water you consume. This is, without a doubt, the number one cause of tummy troubles in the region.
Rule Number One: Don’t Drink the Tap Water!
I cannot stress this enough. Do not, under any circumstances, drink the tap water in the Gili Islands. It is not treated to be potable. The islands are small, remote, and the infrastructure is not the same as back home. The tap water is often brackish (slightly salty) and can contain a whole host of bacteria that your stomach is simply not prepared to handle. Even a tiny sip while brushing your teeth can be enough to set things off.
Your Water Action Plan:
- 💧 Stick to Sealed Bottles: Always, always drink from sealed, bottled water. Before you twist that cap, give it a quick glance to make sure the plastic seal is fully intact. Every shop (toko) and restaurant sells it.
- 🦷 Brush with Bottled Water: It might feel a bit wasteful, but get into the habit of using your bottled water to brush your teeth. It’s a simple switch that eliminates a major risk.
- 🚿 Shower Savvy: This one might sound a bit over the top, but try to keep your mouth closed while you’re in the shower. You don’t want to accidentally swallow a mouthful of water while you’re belting out your favourite tunes.
The Great Ice Debate: To Chill or Not to Chill?
“But what about the ice in my drink?” I hear you ask. This is a classic travel dilemma. The good news is that in almost all reputable tourist bars, restaurants, and hotels on the Gilis, the ice is perfectly safe. It is commercially produced using filtered, purified water and is delivered in big bags. These establishments know that sick tourists are bad for business!
However, if you’re eating at a very small, local warung off the beaten path and you’re feeling a little cautious, there’s absolutely no harm in playing it safe. Just ask for your drink “tanpa es” (pronounced “tan-pa ess”), which simply means “without ice.”
Tip 2: Eat Smart to Keep Your Gili Holiday Tummy Happy
The food in Indonesia is incredible a vibrant explosion of flavour, spice, and colour. You should absolutely dive in and enjoy it! But eating smart is key to ensuring your culinary adventures are memorable for all the right reasons.
Choosing Your Eatery Wisely
Here’s a golden rule of travel that has served me well all over the world: eat where it’s busy, especially if it’s busy with locals. A high turnover of customers is a fantastic sign. It means the food isn’t sitting around for hours; it’s being cooked fresh, and it’s so good that people keep coming back for more.
The Gilis are dotted with warungs, which are small, often family-run eateries serving up delicious local fare. Don’t be afraid to try them—they often have the most authentic and tasty food! Just use your common sense. Take a quick peek before you commit:
- Does the place look generally clean and tidy?
- Are they cooking the food to order?
- Are they handling money and then food without washing their hands? (This is a red flag anywhere in the world!)
Finding safe food in the Gili Islands is all about being observant. Your gut instinct is often your best guide!
What to Eat and What to Avoid
Navigating the menu can feel like a minefield when you’re trying to be cautious, but it doesn’t have to be. Here’s a simple table to help you make savvy choices.
| Go For It! 👍 | Think Twice… 🤔 |
| Piping Hot Food: Anything cooked to order and served steaming hot. Think delicious Nasi Goreng (fried rice), Mie Goreng (fried noodles), or grilled fish and satay sticks straight off the BBQ. The heat kills off any nasty bacteria. | Lukewarm Buffets: Food that has been sitting out for a while in a bain-marie is a potential breeding ground for germs. |
| Peel-It-Yourself Fruits: Bananas, oranges, mangoes, mangosteens, and rambutan are all fantastic choices because you remove the outer layer, which might have been washed in tap water. | Pre-Cut Fruit & Salads: These can be risky. You don’t know if they were washed in tap water or how long they’ve been sitting out. |
| Fresh Young Coconuts: The ultimate safe, natural, and hydrating drink. They chop it open right in front of you. It’s nature’s electrolyte drink! | Undercooked Meat or Seafood: This is a universal rule for food safety. Make sure your fish is flaky and your meat is cooked through. |
| Bread and Baked Goods: Generally very safe and a good option if your stomach is feeling a little delicate. | Sauces Left on Tables: Be a little wary of sauces, especially chilli sambal, that have been sitting out on tables all day in the sun. |
Tip 3: Master the Art of Hand Hygiene
This tip is so simple, yet it’s one of the most powerful tools in your arsenal for preventing a tummy bug. Think of your hands as a superhighway for germs; they touch everything from door handles and cash to menus and tables. Then, without thinking, they touch your face or your food.
Make this your mantra: Wash, sanitise, repeat.
- Wash Your Hands: Make a point of washing your hands with soap and water frequently, and always before you eat and after using the loo.
- Carry Hand Sanitiser: A small bottle of alcohol-based hand sanitiser (with at least 60% alcohol) is an absolute non-negotiable. Pop it in your bag and use it liberally throughout the day. It’s your new best friend.
Tip 4: Pack a Proactive First-Aid Kit
Hope for the best, but prepare for the worst. While you can do everything right and still get unlucky, having a small, well-stocked first-aid kit can make a world of difference. While the Gili Islands do have clinics, they are for basic care. Having your own supplies means you can act fast and start feeling better sooner.
Be Your Own Gili Holiday Health Hero
Here’s a checklist of what to pop in your medical bag. Think of it as your personal ‘tummy bug survival kit’.
- 💊 Rehydration Salts: This is the most important item. If you do get sick, diarrhoea and vomiting can dehydrate you quickly. Oral rehydration solutions (like Dioralyte or Hydralyte) are scientifically formulated to replace the salts and electrolytes your body has lost. The local sports drink, Pocari Sweat, is also an excellent alternative and sold everywhere.
- 💊 Anti-diarrhoea Medication: Something like Loperamide (Imodium) can be a real lifesaver, especially if you have a travel day ahead of you. It works by slowing down your gut. Important Caveat: Don’t use it if you have a high fever or see blood in your stool, as this can indicate a more serious infection that your body needs to expel. In that case, see a doctor.
- 💊 Activated Charcoal: Many seasoned travellers swear by activated charcoal tablets. The theory is that their porous surface helps to trap toxins and chemicals in the gut, allowing them to be flushed out of the body.
- 💊 Probiotics: A healthy gut is a resilient gut! Consider taking a good quality probiotic for a week or two before your trip and continuing throughout your holiday. This can help to bolster your gut flora, making it better prepared to fight off foreign invaders.
- 💊 Antiseptic Wipes & Plasters: Always handy for any minor cuts and scrapes.
Tip 5: Be Mindful with Your Drinks (And We Don’t Just Mean Water)
Being on holiday often means enjoying a few sundowners, and there’s nothing better than a cold Bintang as you watch the sky turn crimson over the ocean. But it pays to be a little mindful.
- Go Easy on the Alcohol: Excessive alcohol can irritate your stomach lining, dehydrate you (which is the last thing you need in a hot climate), and lower your immune system’s ability to fight off bugs. Pace yourself!
- The Arak Warning: Arak is a local spirit made from distilled rice or palm sap. While it’s a traditional part of the culture, you need to be very cautious. There have been tragic and well-documented incidents of methanol poisoning from illegally or poorly brewed batches of Arak. Methanol can cause blindness and even death. To stay safe, avoid cheap cocktail deals that seem too good to be true and stick to beer, wine, or cocktails made with imported, branded spirits at reputable, established bars.
Tip 6: Embrace Local Remedies (Safely!)
Sometimes, despite your best efforts, you might just feel a little… off. If it’s just a mild case of an unsettled stomach, you can try what the locals use.
- 🌿 Tolak Angin: You will see these little yellow and brown sachets of herbal liquid for sale in every single shop. The name translates to “expel the wind,” and it’s Indonesia’s go-to remedy for feeling unwell, nauseous, or bloated. It’s a mix of ginger, mint, honey, and other herbs. It has a unique, strong taste, but many find it genuinely soothing.
- 🍚 The BRAT Diet: If your stomach needs a break, stick to the tried-and-tested BRAT diet: Bananas, Rice, Applesauce, and Toast. Plain boiled potatoes and plain rice are also excellent, gentle options.
Tip 7: What to Do If the Tummy Bug Bites Back
Okay, so the worst has happened. You’ve been hit with a tummy bug on your Gili holiday. First of all, don’t panic. The vast majority of cases are mild and will resolve on their own within a few days. The key is to manage the symptoms and help your body recover.
Don’t Panic – Rehydrate, Rest, and Recover
If you find yourself unwell, here is your simple, three-step game plan. Knowing how to treat a tummy bug in the Gili Islands will make the whole experience far less stressful.
- Hydrate, Hydrate, Hydrate: This is your absolute number one priority. Dehydration is the biggest risk. Sip constantly throughout the day on bottled water, oral rehydration solutions, weak tea, or clear broths. Avoid sugary drinks and caffeine. Take small, frequent sips rather than big gulps if you’re feeling nauseous.
- Rest Up: Your body is fighting an infection, and it needs all the energy it can get. Cancel that snorkelling trip, find a cool, air-conditioned room, and let your body do its thing. Binge-watch that series you downloaded, read a book, and just take it easy.
- Eat Plainly: When you feel your appetite starting to return, be gentle with your stomach. Reintroduce simple, plain foods like those from the BRAT diet. Avoid anything spicy, greasy, oily, or heavy for at least a couple of days.
When to See a Doctor
Listen to your body. You are the best judge of whether this is just a standard bug or something more serious. You should seek medical attention from a local clinic if you experience any of the following red flags:
- Symptoms that aren’t improving or are getting worse after 3-4 days.
- A high, persistent fever.
- Blood or pus in your stool.
- Signs of severe dehydration (e.g., dizziness, confusion, very little or no urination, extreme weakness).
- Severe and unrelenting stomach pain.

Frequently Asked Questions (FAQ)
1. Can I brush my teeth with the tap water in the Gilis?
It is very strongly recommended that you do not. The tap water is not potable and can contain bacteria that can make you sick. Always use bottled water to be safe.
2. Is it safe to eat from the Gili Trawangan night market?
Absolutely! The Gili T night market is a fantastic experience and a great place to get delicious, affordable local food. Just apply the same rules: choose stalls that are busy and popular. Watch them cook your food make sure the fish or satay is grilled fresh in front of you and served hot.
3. Are there really no hospitals on the Gili Islands?
That’s correct. There are no hospitals. There are several good medical clinics that can handle common illnesses and minor injuries. For any serious medical emergency, you will need to be evacuated by speedboat to a hospital on the main island of Lombok, which is why travel insurance that covers medical evacuation is so vital.
4. Should I take antibiotics with me just in case?
It’s generally not a good idea to self-prescribe antibiotics. Most cases of traveller’s diarrhoea are caused by viruses, which antibiotics don’t work against. Taking them unnecessarily can wipe out the good bacteria in your gut and even lead to antibiotic resistance. If your illness is severe or prolonged, see a doctor at one of the clinics; they can diagnose the issue properly and prescribe antibiotics if they are actually needed.
5. What about mosquitos? Is malaria a risk on the Gilis?
The Gili Islands are considered a very low-risk area for malaria, and anti-malarial medication is not typically recommended. However, Dengue fever, which is also transmitted by mosquitos, is a risk throughout Southeast Asia. The mosquitos that carry Dengue bite during the daytime. The best prevention is to avoid being bitten by using a good quality insect repellent (containing DEET), especially during dawn and dusk, which are peak mosquito hours.
A tummy bug is not a rite of passage, and it’s certainly not an inevitable part of a trip to Southeast Asia! By being a little bit mindful and following these simple, sensible tips, you can give yourself the best possible chance of having an incredible, adventure-filled, and most importantly, healthy holiday in the Gili Islands.
