Yes, Oral Rehydration Solution (ORS) can be safely given to pregnant women. ORS is recommended for treating and preventing dehydration in pregnant women suffering from conditions like diarrhea, vomiting, or excessive heat exposure. The standard ORS formulation contains sodium, potassium, chloride, citrate, and glucose in specific proportions that help the body absorb water more efficiently. For home preparation, mix 6 level teaspoons of sugar and 1/2 level teaspoon of salt in 1 liter of clean drinking water. Pregnant women should drink ORS slowly, taking small sips frequently rather than large amounts at once. They should continue normal food intake alongside ORS when possible. ORS works because the glucose in the solution enhances sodium and water absorption in the small intestine through a coupled transport mechanism, which helps restore fluid balance without disrupting the developing fetus. Maintaining proper hydration during pregnancy is particularly important as dehydration can contribute to complications like preterm labor or reduced amniotic fluid levels.
According to a study published in the Indian Journal of Pediatrics 1, maternal knowledge and practices towards diarrhea and oral rehydration therapy are crucial in preventing dehydration in pregnant women. Although the study focused on mothers of under-five children, its findings highlight the importance of awareness and proper use of ORS in preventing dehydration.
The World Health Organization (WHO) oral rehydration solution, which contains sodium, glucose, chloride, potassium, and citrate, is the most effective and safe treatment for dehydration due to diarrhea 2, 3. A study published in the Boletin medico del Hospital Infantil de Mexico 3 found that the WHO oral rehydration solution is effective in treating dehydration due to diarrhea and preventing hypernatremia.
In the context of pregnancy, a study published in the Boletin de la Oficina Sanitaria Panamericana 4 found that isotonic rehydration therapy was effective in treating acute choleraic diarrhea in pregnant women. Although the study did not specifically focus on ORS, its findings suggest that oral rehydration therapy can be safely used in pregnant women.
Overall, the available evidence suggests that ORS can be safely given to pregnant women to treat and prevent dehydration. Pregnant women with dehydration should be encouraged to drink ORS slowly and continue normal food intake alongside ORS when possible.
