What Is ORS?

An oral rehydration solution (ORS) is a mixture of electrolytes, sugar and water. The solution is taken by mouth to absorb water and electrolytes into the body and restore the electrolyte and fluid balance lost by excessive sweating, vomiting or diarrhoea [3].

Studies point out that ORS is an effective treatment for 90-95 per cent of patients suffering from diarrhoea, regardless of the cause [4]. ORS was first developed as a treatment for diarrheal diseases as it helps counter the stomach acid and ease the condition.

Most ORS solutions focus on increasing the sodium or potassium content on the body because that helps the intestines in absorbing more water. ORS solutions can be made at home and are available at all chemist stores.


What Are The Health Benefits Of ORS?

Help treat diarrhoea: Drinking ORS can help replace the lost fluids and essential salts which were lost from your body due to diarrhoea. The glucose contained in ORS solution enables the intestine to absorb the fluid and the salts more efficiently. Thereby help in preventing or treating dehydration and reducing complications and death [5].

Good for dehydration: ORS drink is a combination of salt, sugar and water, which makes it great for people suffering from dehydration [6]. When an individual loses too much glucose or salt from the body due to excess sweating, drinking the ORS solution can help regain the lost glucose and salt. Studies have pointed out that drinking ORS can help replenish the blood with the required minerals or electrolytes, which are lost during any illness [7].

Beneficial for athletes: For an individual who sweats out a lot in the gym or on the tracks, ORS solution is a good choice as it can help one feel active even after a long session of practice [8].

Treats fatigue and weakness: When the levels of fluids in your body reduces, it can cause you to feel fatigued and weak. Drinking a glass of ORS solution can help replenish the lost fluids and make you feel energised quick.


How To Make ORS At Home?

Though the ORS is available over the counter in any medical store, in case of an emergency, one need not worry, as this drink can be easily prepared at home.

  • 5 tsp sugar
  • ½ tsp salt


  • Take a jar and, fill it with clean drinking water.
  • Add about five tablespoons of sugar and, half tablespoon of salt.
  • Mix it well using a spoon until the contents are thoroughly mixed.

Note: You should be very careful about the amount of sugar and salt you use to prepare ORS solution.

Caution: Do not add anything extra, apart from these ingredients. You should not use any added colour or artificial sweeteners.

For storage: You can store the ORS solution in your refrigerator. But see to it that you do not use this mixed ORS after 24 hours. You need to prepare it fresh one if after 24 hours.
