What is Oral Rehydration Therapy (ORT)?
Oral Rehydration Therapy (ORT) is a cost-effective and life-saving treatment for dehydration using a simple solution of water, salts, and sugar.
Oral Rehydration Therapy (ORT) is a cornerstone in the treatment of dehydration, particularly in cases of diarrhea and vomiting. It involves administering a specific solution of water, salts (electrolytes), and sugar orally to replenish fluids and electrolytes lost due to illness. ORT is especially critical for children and individuals in resource-limited settings, and it is recommended by the World Health Organization (WHO) and UNICEF as a primary intervention for dehydration. Studies have shown that ORT can reduce mortality rates from diarrheal diseases by up to 93% when administered promptly and correctly.
Key Components of Oral Rehydration Solution (ORS)
Water
Clean and safe water is the base of the ORS. It helps to restore the fluid volume lost due to dehydration. The WHO recommends using boiled and cooled water if clean water is not readily available.
Salts (Electrolytes)
Electrolytes like sodium, potassium, and chloride are essential for maintaining fluid balance and nerve function. Diarrhea and vomiting can deplete these electrolytes, leading to further complications. ORS helps replenish these crucial salts.
Sugar (Glucose)
A small amount of sugar (glucose) aids in the absorption of sodium and water in the intestine. This synergistic effect enhances the effectiveness of the rehydration process. The WHO/UNICEF ORS formulation contains a specific concentration of glucose for optimal absorption.
How to Administer Oral Rehydration Therapy
- Use a commercially prepared ORS packet: These packets contain the correct balance of salts and sugar and should be mixed with the specified amount of water.
- If ORS packets are unavailable, a homemade solution can be prepared (see FAQ), but ensure accurate measurements.
- Administer small, frequent sips of the solution, especially to children, to prevent vomiting.
- Continue breastfeeding infants while administering ORS.
- Monitor the individual for signs of improvement, such as increased urination and reduced thirst.
- Seek medical attention if dehydration worsens or if there are signs of severe dehydration (e.g., lethargy, sunken eyes).
- Do not use sugary drinks like soda or juice as substitutes for ORS, as they can worsen dehydration.
Common Causes of Dehydration Treatable with ORT
| Condition | Description | |
|---|---|---|
| 1 | Diarrhea | Frequent, watery stools leading to significant fluid and electrolyte loss. |
| 2 | Vomiting | Expulsion of stomach contents, causing fluid and electrolyte depletion. |
| 3 | Heatstroke | Elevated body temperature and excessive sweating, resulting in dehydration. |
| 4 | Intense Exercise | Prolonged physical activity leading to fluid loss through perspiration. |

Consult with a healthcare professional for personalized recommendations, especially for infants, young children, and individuals with underlying health conditions. Severe dehydration requires immediate medical intervention.
Frequently Asked Questions
What is the correct ratio of ingredients for a homemade oral rehydration solution if I don't have pre-made packets?
If pre-made ORS packets are unavailable, you can prepare a homemade solution using the following guidelines: Mix 6 level teaspoons of sugar and ½ level teaspoon of salt in 1 liter (5 cups) of clean water. It is crucial to use accurate measurements to ensure the solution is safe and effective. Improper concentrations can worsen dehydration.
Can I use sports drinks for oral rehydration therapy?
Sports drinks are not ideal for ORT. While they contain electrolytes, they often have a high sugar content, which can draw more water into the intestine and potentially worsen diarrhea. The electrolyte balance in sports drinks is also not optimized for rehydration after significant fluid loss. ORS is the preferred solution.
How often should I give the oral rehydration solution?
The amount of ORS needed depends on the age and weight of the individual, as well as the severity of dehydration. As a general guideline, infants should receive 50-100 ml (2-4 ounces) after each loose stool or vomiting episode, while older children and adults can take 100-200 ml (4-8 ounces). Administer small, frequent sips to minimize the risk of vomiting. Continue until dehydration is resolved.
When should I seek medical attention for dehydration despite using oral rehydration therapy?
Seek immediate medical attention if the individual shows signs of severe dehydration, such as lethargy, sunken eyes, inability to drink, decreased urination, or severe abdominal pain. If ORT does not improve the condition within a few hours, or if the individual has underlying health conditions, consult a healthcare professional promptly.
