What is ORS?

ORS Full Form is Oral Rehydration Solution. In order to rehydrate the body and replenish electrolytes, ORS is a combination of water, sugar, and salts. Researchers at the World Health Organization (WHO) created it for the first time in the 1960s as a simple, affordable way to treat diarrhea-related dehydration. Today, ORS is widely accessible and used to treat a variety of conditions that result in fluid loss, including vomiting, fever, and excessive perspiration, in addition to diarrhea.

The Science Behind ORS

Osmosis is a process that is used in ORS to correct the body’s electrolyte balance. Minerals known as electrolytes, which carry an electrical charge, are necessary for healthy cellular function. Dehydration causes us to lose electrolytes, and when our cells can’t function properly, we experience symptoms like fatigue, cramps in our muscles, and lightheadedness.

A precise electrolyte and glucose balance found in ORS aids the body’s better absorption of nutrients and water. The glucose in ORS stimulates the body’s absorption of sodium and other electrolytes, aiding in the restoration of the fluid balance. ORS contains sodium, which aids in water retention and halts further dehydration.

How to Use ORS

ORS is easy to use and can be administered at home or in a healthcare setting. The WHO recommends the following steps for preparing and using ORS:

  1. Wash your hands with soap and water before handling ORS.
  2. Mix one sachet of ORS (usually containing around 27.9 grams of powder) with one liter of clean water. If clean water is not available, boil or filter the water first.
  3. Stir the mixture well until the powder is completely dissolved.
  4. Give the solution to the patient in small, frequent sips.
  5. Continue to give ORS until the patient’s condition improves.

It is important to note that ORS should not be used as a substitute for other fluids, such as breast milk or formula, in infants and young children.

Benefits of ORS

ORS has several benefits, including:

  • It is inexpensive and widely available, making it accessible to people in low-resource settings.
  • It is easy to use and can be administered at home, reducing the need for hospitalization.
  • It is effective at treating dehydration caused by a variety of conditions, not just diarrhea.
  • It is safe and has few side effects.
  • It can save lives by preventing severe dehydration and its complications.


ORS is a simple but powerful solution for treating dehydration caused by a variety of conditions. It works by restoring the balance of electrolytes in the body and promoting the absorption of water and nutrients. ORS is inexpensive, easy to use, and has saved countless lives around the world. If you or someone you know is experiencing dehydration, consider using ORS as a safe and effective remedy.

Frequently Asked Questions

Q.1 Is ORS only for treating diarrhoea?

No, ORS can be used to treat dehydration caused by a variety of conditions, including vomiting, fever, and excessive sweating.

Q.2 Is ORS safe for infants and young children?

Yes, ORS is safe for infants and young children. However, it should not be used as a substitute for other fluids, such as breast milk or formula, in infants and young children.

Q.3 Can I make ORS at home?

While it is possible to make a homemade ORS solution using ingredients like salt, sugar, and clean water, it is generally recommended to use commercially available ORS sachets. This is because homemade solutions may not have the precise balance of electrolytes and glucose needed to effectively treat dehydration.

Q.4 How long does it take for ORS to work?

ORS can start working within a few hours of administration, but it may take several hours or even days to fully restore fluid and electrolyte balance in the body.

Q.5 Can I overdose on ORS?

While it is unlikely to overdose on ORS, taking too much can lead to hypernatremia, a condition in which there is too much sodium in the blood. To avoid this, it is important to follow the recommended dosage and not exceed the amount of ORS recommended for your age and weight.
