Common Tourist Illnesses in Bali: What’s Normal vs What’s Not
Bali stands as one of the world’s favourite destinations, with its breathtaking beaches, vibrant culture, and warm hospitality. Yet, as any frequent traveller will attest, new environments and tropical climates can sometimes come with health risks. At Trishnanda Care Centre, we’re dedicated to supporting tourists’ health and well-being wherever you are on the island. This blog will guide you through the most common tourist illnesses in Bali, how to know what’s “normal” and when it’s time to seek help, and how our 24/7 mobile healthcare team can bring fast, reliable medical care straight to your door.
Understanding Your Risks: Why Do Travellers Get Sick in Bali?
Travel exposes your body to new foods, bacteria, viruses, and environmental factors. In Bali, the tropical climate, different culinary practices, and occasionally variable hygiene standards can make even experienced explorers vulnerable to illness.
Main Contributors:
• Food & Water Contamination: Changes in diet or exposure to unfamiliar microbes.
• Mosquito-Borne Illnesses: Tropical regions have higher risks of dengue and other vector-borne diseases.
• Jetlag & Fatigue: Long flights disrupt your immune system.
• Heat & Humidity: Increased risk of dehydration and heat-related issues.
Bali Belly: The Most Common Complaint
“Bali Belly” is the colloquial term for traveller’s diarrhea. It affects many international visitors at some point during their stay.
What’s Normal
• Mild diarrhea (2–3 loose stools per day)
• Minor stomach cramps
• Light nausea
• Mild loss of appetite
These symptoms often resolve within 24–72 hours with rest, hydration, and a simple diet. Oral rehydration salts and plenty of fluids are usually sufficient.
What’s Not Normal
Seek medical help if you experience:
• Severe or persistent vomiting
• High fever (above 38.5°C)
• Blood in stool or vomit
• Inability to keep fluids down
• Signs of dehydration (dizziness, dry mouth, minimal urination)
• Symptoms lasting more than 3 days
Our Bali Belly IV Therapy can be delivered directly to your villa or hotel for rapid recovery. For mothers-to-be suffering from Bali Belly, we offer a specialised Bali Belly Mom Care IV Therapy package.
Tip: Be cautious with street food if you have a sensitive stomach. Wash hands frequently and avoid tap water.
Food Intolerance & Allergic Reactions
Bali’s unique cuisine brings new flavours and sometimes unexpected ingredients.
What’s Normal
• Mild bloating or gassiness
• Temporary discomfort after unfamiliar foods
What’s Not Normal
Seek immediate care if you have:
• Difficulty breathing or swelling of lips/tongue (signs of anaphylaxis)
• Severe stomach pain or vomiting after eating
• Rash or hives all over your body
We provide targeted Food Intolerance IV Therapy to manage symptoms at your location.
Heat Exhaustion & Dehydration
The Balinese sun can be much stronger than expected.
What’s Normal
• Mild headache
• Feeling tired after long exposure
• Light sweating
What’s Not Normal
Call for help if you experience:
• Confusion or fainting
• Rapid pulse
• No sweating despite heat
• Nausea/vomiting that prevents fluid intake
• Dark urine or no urination for hours
Our Hydration IV Therapy is popular among tourists for quick rehydration after sun exposure or during recovery from illness. Always drink bottled water and use sunscreen.
Mosquito-Borne Illnesses: Dengue Fever & Others
Dengue is endemic to Bali and peaks during rainy season (October–April).
Early Symptoms (What’s Normal)
• Sudden high fever (usually above 39°C)
• Headache behind the eyes
• Muscle/joint pain
• Mild rash
If you experience these symptoms after a mosquito bite and have recently arrived in Bali, monitor closely.
Concerning Signs (What’s Not Normal)
Seek urgent care if:
• Severe abdominal pain
• Persistent vomiting
• Bleeding from gums/nose/easy bruising
• Extreme fatigue or restlessness
We offer in-villa Dengue NS1 + CBC testing for fast diagnosis, as well as Dengue IV Therapy for symptom relief and recovery support.
Prevention Tip: Use mosquito repellent day and night. Sleep under nets where available.
Jetlag & Fatigue: Adapting To A New Time Zone
Long-haul flights disrupt sleep cycles and weaken immunity.
What’s Normal
• Daytime sleepiness
• Mild irritability
• Stomach upsets on arrival
What’s Not Normal
If fatigue persists beyond a week or you develop:
• Severe insomnia affecting daily function
• Mood changes (depression/anxiety)
• Palpitations or chest pain
Our Jetlag IV Therapy helps replenish nutrients lost during travel and accelerate adaptation.
Hangover & Alcohol Overindulgence
Beach parties are part of the Bali experience but excessive drinking can be risky in hot climates.
What’s Normal
• Headache, mild nausea the morning after drinking
• Mild dehydration symptoms
What’s Not Normal
Call for help if:
• Persistent vomiting preventing fluid intake
• Severe abdominal pain or confusion
• Signs of alcohol poisoning (seizures, slow breathing)
Our Hangover IV Therapies provide rapid rehydration and symptom relief delivered anywhere on the island.
Skin Infections & Sunburn
Humidity plus sun exposure can irritate skin or worsen wounds/tattoos.
What’s Normal
• Mild redness or peeling from sunburn
• Small insect bites with mild itching
What’s Not Normal
Medical attention is needed if:
• Blistering sunburn covering large areas
• Spreading redness/swelling around wounds/tattoos (possible infection)
For new tattoos exposed to travel environments, our Tattoo After-Care IV Therapy supports healing from within.
Respiratory Infections: Coughs, Colds & Flu-like Symptoms
Crowded tourist spots increase transmission of viral infections year-round.
What’s Normal
Common cold symptoms:
• Mild sore throat/cough
• Slight fever (<38°C)
Usually self-limiting within a week.
What’s Not Normal
Seek medical help if you develop:
• High fever (>38.5°C) persisting more than 3 days
• Shortness of breath/wheezing
• Chest pain
We offer in-villa Flu IV Therapy as well as Covid Recovery IV Therapy if you test positive during your stay.
Tip: Masks are recommended in crowded indoor places if you are immunocompromised.
Chronic Conditions Flared by Travel: Asthma, GERD & More
Travel stressors may trigger chronic conditions like asthma attacks or acid reflux (GERD).
If you have a history of these issues:
Mild symptoms are normal. If you notice severe shortness of breath, chest tightness unrelieved by inhaler, persistent vomiting/burning pain despite antacids seek care immediately. Our GERD IV Therapy can provide quick relief delivered discreetly wherever you stay.
Preventive Care: Vaccinations & Lab Testing On The Go
Some illnesses are preventable with proper vaccinations before arrival. For those requiring documentation for visas or peace of mind after exposures (such as STDs), our team provides in-villa lab testing including dengue panels, thyroid checks, full STD panels, and travel vaccinations without you needing to leave your accommodation.
