ORS | What are Oral Rehydration Salts?

ORS full form is Oral Rehydration Solution. It is a sugar and electrolyte solution. It was created as a therapy for diarrheal disorders at first. 

It is used to cure Diarrhea. Diarrhoea can also cause your body to become slightly acidic, which is harmful to your cells. So, in addition to glucose and electrolytes, ORS contains a base, which neutralises the acid.

What are Oral Rehydration Salts?

Oral rehydration salts (ORS) are a water-soluble combination of electrolytes (salts) and carbohydrates (in the form of sugar). When you experience dehydration due to gastroenteritis, diarrhoea, or vomiting, they are used to restore the salts and water that your body loses.

Unlike other liquids you could drink to replenish what you’ve lost, the proportion of salts and sugar in an ORS is exactly what your body requires to heal.

Pharmacies sell commercially accessible ORS goods like beverages, ice blocks, sachets, and effervescent tablets for preparing solutions. They are frequently available in a variety of flavours.

If rehydration drinks are not accessible, homemade salt/sugar combinations are used in underdeveloped countries, but they must be prepared carefully because too much salt can be hazardous.

Mechanism of action of an oral rehydration solution

ORS works because glucose increases sodium and thus water absorption in the small intestine (sugar). A system is known as “the sodium-glucose cotransport mechanism” transports the two over the small intestine’s wall together. 

Toxins that induce diarrheal illnesses, such as those caused by food poisoning, enhance water secretion in the small intestine but do not inhibit water uptake by the sodium-glucose transport system. 

If you use ORS to treat diarrhoea, it will not cure you, but it will rehydrate you.

How to make oral rehydration salts solutions?

Follow the instructions on the label for preparing the oral rehydration salts if you have powder sachets or effervescent pills that need to be mixed with water. Never take it without first diluting it with water.

Mix the contents of the sachet with fresh drinking water. Before mixing the contents of the sachet with Pepi/infants, use boiled and cooled water.

After mixing the ORS solution, do not boil it.

Some ORS products (such as Pedialyte) must be consumed within one hour of being mixed. Unless you keep it in the refrigerator for up to 24 hours, any unused solution (ORS combined with water) should be thrown away.

Important points to follow when using ors

Unless your doctor has informed you otherwise, you should not take oral rehydration salts to treat diarrhoea for longer than 2–3 days.

To combine the oral rehydration salts, just use water; do not use milk or juice, and never add extra sugar or salt. This is because rehydration salts have the ideal balance of sugar and salts to aid the body.

You must use the correct amount of water to make up the medicine, as too much or too little can cause an imbalance in the salts in your child’s body.

Oral rehydration salts are generally safe and have few negative effects.

Other drugs can be taken at the same time as oral rehydration salts.

Fizzy beverages, undiluted juices, tea, coffee, and sports drinks should all be avoided due to their high sugar content, which can promote dehydration.

Benefits of ORS

There are numerous advantages of drinking ORS rehydration drink, including the following:

Excellent for Dehydration

Dehydration sufferers can benefit from ORS, which is a combination of sugar and water with electrolytes. When the body loses too much glucose or dehydration causes salt loss, ORS drinks can assist replace the salts and glucose that have been lost. This aids in the replenishment of essential minerals and electrolytes that the body may lose during illness.

Aids in the Treatment of Diarrhea

ORS has been shown in studies to help prevent and manage dehydration, as well as other issues that are typical in people who have diarrhoea.

Reduces Fatigue and Weakness

The loss of fluids is the primary cause of weariness and weakness in the body. This loss makes you dizzy, and you may even feel tired at times. Due to its fundamental job of replenishing fluids into the body to make you feel active and energetic, consuming ORS can readily relieve fatigue and weakness.

Athletes Will Benefit

Rehydration is an essential part of each athlete’s life. When they’re on the field, training, or working out in the gym, they sweat profusely. Rehydration pills can help an athlete feel more active and increase performance, which could otherwise suffer from a loss of energy caused by electrolyte loss. It also protects the athlete from injury.

What is MCB?


ORS is the most precise hydrating solution available, as it can be produced in seconds and quickly combats weakness, exhaustion, and dehydration.
