Can a probiotic yeast shorten diarrhea in toddlers?
NCT ID NCT07813182
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are testing whether adding the probiotic yeast Saccharomyces boulardii to standard care helps children aged 6 months to 5 years recover faster from acute diarrhea. All children receive fluids and zinc, and half also receive the probiotic from hospital admission to discharge. The trial tracks how long diarrhea lasts, how often children have bowel movements, stool consistency, hospital stay length, side effects, costs, and readmission rates.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a probiotic yeast supplement called Saccharomyces boulardii
- What this could lead to
- If it helps, this could give doctors a low-cost add-on to standard diarrhea care that shortens illness and hospital stays for young children.
- What could go wrong
- Probiotics do not help every case of diarrhea, and some children may have bloating or rash. The trial may show no clear benefit over standard fluids and zinc alone.
