The essential factors recommended by the World Health Organization for the control of acute gastroenteritis include the use of oral rehydration solution (ORS) with reduced osmolality and, if needed, intravenous fluids and zinc supplements. Many studies have suggested the consumption of probiotics as an adjunct method for the treatment of acute diarrhea. Materials and Methods: The present study was done at our tertiary care centre to evaluate the efficacy of addition of Zinc and Saccharomyces boulardii (probiotic) to WHO-ORS and compare those effects with WHO-ORS alone. Results and conclusion: In our study children receiving Probiotic were more likely to be diarrhea-free after the first 48 hours of intervention, with better outcomes at 72 and 96 hours along with improvement in consistency and reducing the duration of hospital stay.
