If you’re suffering from Bali Belly, you’ve probably been told to ‘stay hydrated.’ But when you’re losing fluids rapidly, water alone is not enough. This is where Oral Rehydration Salts—known locally and by its brand name Oralit—become the most important item in your health kit. This guide explains what it is, why it works, and how to use Oralit correctly.

Why Water Isn’t Enough: The Science of Dehydration
When you have diarrhea, your body doesn’t just lose water. You also lose critical electrolytes like sodium and potassium, as well as glucose, which your body needs for energy. This leads to dehydration.
Drinking plain water doesn’t replace these lost electrolytes and can sometimes worsen the electrolyte imbalance in your body, leaving you feeling weak and dizzy. It is crucial to be able to recognize the symptoms of dehydration early.
How Oral Rehydration Salts (ORS) Actually Work
The magic of Oralit for Bali Belly lies in its perfectly crafted formula.
The Scientifically-Backed Formula
Oral Rehydration Salts (ORS) are not just a simple salt and sugar mix. The formula, recommended by the World Health Organization (WHO), contains a precise, scientifically-backed ratio of glucose, sodium, and potassium designed to tackle diarrheal dehydration with maximum efficiency.
The “Glucose-Sodium Co-transport” Explained Simply
The secret to its effectiveness is a biological process that feels like magic. Think of it this way: The glucose (sugar) in Oralit acts like a special ‘key’. This key unlocks a ‘door’ in your intestinal wall. This specific doorway is designed to pull in sodium (salt), and wherever sodium goes, water follows through osmosis. This ‘co-transport’ mechanism actively pulls water back into your body’s cells far more effectively than drinking plain water ever could.
A Practical Guide to Using Oralit in Bali

Using Oral Rehydration Salts in Bali is simple and accessible.
Where to Buy It
You can find Oralit at any pharmacy (‘Apotik’) and most convenience stores (like Indomaret, Circle K, and Alfamart) across Bali. It is very affordable and readily available, making it an easy addition to your first-aid kit.
How to Mix It Correctly
Follow the instructions on the sachet precisely. Typically, you mix one sachet of powder into 200ml of safe, sealed bottled water. Stir until it’s completely dissolved. It’s important not to add any extra sugar, juice, or other flavorings, as this can disrupt the scientific balance and make it less effective.
How to Drink It for Maximum Effect
Don’t gulp it down, especially if you’re feeling nauseous. Take small, frequent sips throughout the day. A good rule of thumb is to aim to drink one full glass of the solution after each bout of watery diarrhea to replace the fluids you’ve lost.
When Oral Rehydration Isn’t Enough
Oral rehydration is highly effective as long as you can keep fluids down. However, if you are vomiting persistently and cannot tolerate even small sips of Oralit, your body cannot rehydrate itself, and you are at risk of severe dehydration.
This is a clear sign you need to see a doctor. Medical intervention like IV Drip therapy may be necessary to bypass the digestive system and deliver fluids directly into your bloodstream.
Never underestimate the power of this simple sachet. Proper use of Oralit is the key to managing mild to moderate dehydration at home and is the first line of defense in your Bali Belly recovery.

Frequently Asked Questions (FAQ) about Oralit
What does Oralit taste like?
Oralit has a mildly salty and slightly sweet taste. It is not a flavored beverage, but it is generally easy to drink. Some brands may offer a slight orange or lemon flavor.
Can I mix Oralit with juice instead of water to improve the taste?
It is not recommended. The scientific balance of sugar and salt is crucial for its effectiveness. Adding extra sugar from juice can disrupt this balance and may even worsen diarrhea. Always mix with clean, bottled water as directed.
Are sports drinks like Pocari Sweat a good substitute for Oralit?
Sports drinks can help, as they contain electrolytes and sugar, but they are not a perfect substitute. Oralit is a medical formulation with a higher concentration of electrolytes specifically designed to treat diarrheal dehydration, whereas sports drinks are designed for rehydration after exercise.
What is the correct dosage for a child?
You must follow the instructions on the packaging or, even better, consult a doctor or pharmacist. The dosage for children is based on age and weight and it’s crucial to get it right.
Can I drink too much Oralit?
It’s difficult to drink a harmful amount if you are using it to replace fluids lost from severe diarrhea. Drink it as needed to quench thirst and after each bowel movement. If you are no longer having diarrhea, you can switch back to plain water.
How long do I need to keep drinking it?
You should continue to drink Oralit as long as you have active, watery diarrhea. Once your stools begin to firm up, you can gradually transition back to drinking plain water.
Can I prepare a large bottle in the morning and drink it all day?
A mixed solution of Oralit should ideally be consumed within 24 hours and should be kept in a cool place if possible. It’s best to mix it fresh as needed to ensure its stability and cleanliness.
Is Oralit the same thing as electrolyte supplements for sports?
They are similar but not the same. Oralit has a very specific ratio of sodium and glucose designed to combat diarrheal dehydration, as recommended by the WHO. Sports electrolyte tablets may have a different profile, often with less sodium and more flavorings.
If I’m drinking Oralit, do I still need to see a doctor?
Yes, if you have any red flag symptoms (high fever, blood in stool, persistent vomiting, symptoms for more than 3 days). Oralit treats the dehydration, but it does not treat the underlying infection.
Does Oralit stop the diarrhea?
No. This is a common misconception. Oralit does not stop diarrhea. Its only job is to prevent and treat the dehydration caused by the diarrhea, which is the most dangerous part of the illness.
