What Is Oral Rehydration Solution (ORS)

Oral Rehydration refers to the process of replenishing lost fluids and electrolytes by drinking a specially formulated solution known as Oral Rehydration Solution (ORS). It is a simple, effective, and life-saving treatment primarily used to prevent or treat dehydration, especially due to diarrhea, vomiting, or excessive sweating.

✅ What Is Oral Rehydration Solution (ORS)?

ORS is a liquid mixture of:

Clean water

Salts (like sodium and potassium)

Sugar (glucose)

This specific combination helps the body absorb fluids more efficiently from the intestines.

💡 How It Works

When someone is dehydrated, their body loses fluids and electrolytes. ORS works by using the glucose to enhance the absorption of sodium and water in the small intestine, which helps quickly rehydrate the body.

🩺 Common Uses of ORS

Diarrhea-related dehydration (especially in children)

Vomiting

Heat-related dehydration

Post-exercise fluid recovery

Travelers’ diarrhea

🧪 WHO-Recommended ORS Formula

The World Health Organization (WHO) recommends this ORS formula per 1 liter of clean water:

2.6 g sodium chloride (table salt)

2.9 g trisodium citrate (or 2.5 g sodium bicarbonate)

1.5 g potassium chloride

13.5 g anhydrous glucose

🏠 Homemade ORS Recipe

If commercial ORS is not available, you can make it at home:

Mix 6 level teaspoons of sugar and 1/2 teaspoon of salt in 1 liter of clean water.

Make sure the measurements are accurate—too much sugar or salt can be harmful.

⚠️ When to Seek Medical Help

While ORS is highly effective, you should see a doctor if:

Dehydration is severe (sunken eyes, lethargy, no urination)

Symptoms persist for more than 24 hours

There's blood in the stool

The person is an infant, elderly, or has other health conditions

🧾 Summary

Oral Rehydration is a safe and effective way to treat mild to moderate dehydration.

ORS can be purchased or made at home.

It’s a vital tool in reducing deaths due to diarrhea and dehydration, especially in children in developing countries.
