Oral rehydration solution (ORS) is used to treat the dehydration or ongoing loss of water. The review discusses the benefits, such as how it helps to reduce length of stay in the hospital and decreases risk of dehydration-related complications. For more information on ORS, read this article!

What is ORS?

ORS stands for the Organic Rehydration Solution.  It is combination of water, salt and sugar. It helps to replenish the diminished water content of the body. Dehydration occurs because of water loss from the body due to vomiting and loose motions. It can also occur because of working in hot weather without taking adequate water.

Standard WHO ORS contains (When constituted in one litre water):

  • Sodium 2.6 grams
  • Glucose anhydrous 13.5 grams
  • Potassium chloride 1.5 grams
  • Trisodium citrate, dihydrate 2.9 grams

ORS has total osmolarity of 245 mmol/litre

How does ORS work?

The purpose of ORS is to rehydrate the body, when you are suffering from a lack of fluids or in need of hydration. 

It does so by combining electrolytes with your body’s natural water balance and making it easier for your cells to absorb all the nutrients and water that’s needed. It’s formulated to work 24/7 and is both safe, effective and non-toxic. 

This means that it’s suitable for use at home or in hospitals. It can be used by those suffering from constipation, diarrhoea or any other need for rehydration. You will be able to get in at a minimum of 1 litre per day.

ORS has glucose and salts in a specific ratio. When glucose and salt is present in a specific ratio with water, in the intestine it helps for better absorption of water in blood.

What are types of ORS?

ORS is made up of two components: a carbohydrate source and electrolytes. The carb source is generally glucose or sucrose, which are then mixed together with salts, like potassium chloride or sodium chloride. There are many types of ORS and they all work differently. Some ORS allow you to drink when you need it while others require you to use reusable packets or a jerrycan. 

ORS that are commercially available are in powder that to be mixed and recommended quantity of water or directly available radiuses solution in tetra packs.

It is available in many different flavours and taste is an issue to consider for use in children. Flavoured ORS is readily available everywhere and it is easy to use in children.

Risk factors for dehydration

Dehydration occurs when a person’s body loses more water than it takes in. It is an important concern for people who participate in endurance or other physical activities because dehydration can lead to cramps, dizziness, and even fainting. Common causes of dehydration include vomiting and diarrhea. Excessive sweating can also deplete a person’s electrolytes and water levels….

Dehydration is a concern for many fitness enthusiasts, but it is not very common in endurance sports. Athletic performance can be affected by dehydration, though the extent to which it affects an athlete depends on how fit the individual is. If a person does not already drink enough fluids during long periods of exertion, this can result in dehydration. Dehydration can also occur as a result of heat in the body.   In heatstroke, a severe case of dehydration can be fatal.  Heatstroke is usually the result of prolonged exposure to hot and humid conditions for a prolonged period of time. 

Gastroenteritis or a gastrointestinal disease can also cause dehydration.

It is important to drink a sufficient amount of fluids to replace lost water and other essential nutrients in the body.
