How to Prepare Oral Rehydration Solution (ORS) and It's Benefits

Updated on 30 September 2022

The human body is chemically made up of, mainly water and organic compounds that comprise lipids, proteins, carbohydrates, and nucleic acids. Water is found in extracellular fluids of our body (the blood plasma, the lymph and the interstitial fluid) and the cells themselves. About 60% of the human adult body comprises water. It is the main constituent of cells, tissues and organs and is vital for life.  

Water and our body: Helps keep the body`s normal temperature, lubricates and cushions joints, and protects the spinal column and sensitive tissues. It also helps eliminate the body`s waste through urination, perspiration and bowel movements. Water serves as a vital nutrient to the life of every cell and regulates our internal body temperature by sweating and respiration.

Dehydration: Our body relies on water to perform basic functions. Sometimes, for various reasons, the body loses more fluid than what is consumed and hence gets dehydrated. It could be due to diarrhoea, vomiting, excessive sweating, workout or low water intake.  So, when the body is dehydrated, bodily functions take a toll.

What is an Oral Rehydration Solution (ORS)?

An Oral Rehydration Solution (ORS) is a special drink containing a precise balance of electrolytes, such as sodium and potassium, and glucose in specific proportions. This solution is formulated to replenish fluids and electrolytes lost due to dehydration caused by diarrhoea or vomiting.

Is oral rehydration therapy safe for children?

ORS is generally safe for children when used as directed. The precise balance of electrolytes and glucose in ORS helps in rapid absorption and rehydration without causing harm. It's essential to follow proper instructions for preparation and dosage according to the child's age and the severity of dehydration. However, consulting a healthcare professional before administering ORS, especially in severe cases, is advisable.
 

What If We Ignore Dehydration?

Since the body relies on water for basic bodily functions, our body needs to be rehydrated. If our body is not treated for dehydration, it could lead to major complications. In such cases, oral rehydration therapy is given to that person as a trusted Dehydration Cure. The person is given ORS (Oral Rehydration Solution) to replenish his body`s fluid levels. ORS is usually given to treat moderate dehydration due to diarrhoea, vomiting or other conditions.

ORS contains a specific amount of glucose and electrolytes (potassium and sodium). These Oral Rehydration Solution components maximise fluid absorption in the gastrointestinal tract. This tract relies on sodium-glucose cotransporters, which help move substances across membranes. Sodium and glucose paired together help in the proper absorption of fluids in the body.  

It is also very safe for children. It is normally used to treat diarrhoea-related dehydration in children. Compared to adults, children are more likely to experience dehydration due to diarrhoea, as they have a higher metabolic rate, meaning they lose body fluids quickly.  Excessive sweating and low water intake can further increase the risk of dehydration in children as they cannot recognise thirst and do not hydrate themselves.

Electrolytes: Properly hydrating our body means keeping our electrolyte levels at an optimal level. Electrolytes help our body in balancing our body in various ways – maintain water levels, move the nutrients into appropriate cells, maintain PH levels, and ensure that our body parts work the way they should.

When should ORS be used?

Oral Rehydration Solution (ORS) should be used in various situations to address dehydration. It is commonly recommended in the following scenarios:

  • Diarrhea: ORS is particularly crucial in treating diarrhea, as it helps replace fluids and electrolytes lost due to excessive bowel movements.
  • Vomiting: When individuals are vomiting, they are at risk of dehydration. ORS can help replenish the lost fluids and electrolytes.
  • Illness and Infections: During illnesses such as flu or infections that lead to fever, there's an increased risk of dehydration. ORS can be used to maintain proper hydration levels.
  • Traveler's Diarrhea: ORS can be beneficial when traveling to regions where waterborne illnesses are prevalent, helping to prevent dehydration.
  • Intense Physical Activity: Athletes or individuals engaging in strenuous physical activities, especially in hot conditions, may use ORS to prevent dehydration.

It's essential to follow healthcare provider recommendations and instructions on when and how to use ORS for specific health conditions. If in doubt or if symptoms persist, consulting a healthcare professional is advisable.

Uses and Benefits of ORS

ORS is considered a safe and effective treatment for dehydration, especially in children experiencing diarrhoea or vomiting. It aids in restoring lost fluids and electrolytes, preventing or treating dehydration-related complications. The benefits of ORS include:

  1. Restoring Fluids: ORS helps replace lost fluids due to diarrhoea or vomiting more effectively than plain water.
  2. Replenishing Electrolytes: It contains essential electrolytes like sodium, potassium, and glucose, which are crucial for maintaining proper hydration and bodily functions.
  3. Preventing Dehydration: Administering ORS promptly can prevent mild dehydration from worsening, particularly in children.
  4. Simple and Safe: ORS is easy to prepare and administer, making it a convenient and safe treatment, even for infants and young children.

Preparation at Home

In emergency situations, one can prepare ORS at home as follows,

  • 1-litre clean drinking water boiled and cooled 5 cupfuls (1 cup -200 ml)
  •  6 level teaspoons of sugar
  • ½ teaspoon of salt

Stir the sugar and salt in the water till fully dissolved.  Now this solution can be used as ORS.

The rough estimate of replacement for older children and adult is weight in kg X 75 ml in the first four hours. Healthy adults can rehydrate themselves by drinking water, clear soup, juice, sports drinks and tea.

A Word of Caution

ORS should be used with caution if the person,
