In simple terms, ORS is nothing but a mixture of salts and sugar. It is used to restore body fluids and electrolytes lost due to dehydration. It can be used by people suffering from gastrointestinal disorders such as diarrhea and vomiting. It acts as an oral rehydration salt (ORS) formula that has been recommended for use by the World Health Organization (WHO). It is also indicated for the treatment of metabolic acidosis.

It can be used to treat muscle cramping caused due to lack of water and electrolytes in the body. In some cases, people recovering from illnesses or those suffering from heatstroke are also recommended to use this powder. It can also be taken for dehydration caused due to exertion while exercising or due to excessive loss of water in hot and/or humid weather.

 In diarrhea, your body tends to lose water and electrolytes such as sodium, chloride, potassium, bicarbonate, etc. If the fluid and electrolyte balance in the body is not maintained by replacing the lost salts and water, dehydration occurs. To prevent dehydration, ORS is recommended. The salt and sugar mixture in ORS stimulates water and electrolyte absorption from the gut, thereby aiding in the replacement of the lost salts in case of diarrhea and vomiting.
