Summary

This study tests whether a probiotic called Escherichia coli 5C (Colipral®) can reduce stomach symptoms like bloating and pain after a colonoscopy. About 160 adults will receive either the probiotic or a placebo for 14 days after the procedure. Researchers will track symptom changes using a standard questionnaire.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Escherichia coli 5C (a probiotic dietary supplement)
What this could lead to
If it works, this could offer a simple, safe way to reduce bloating, pain, and other gut symptoms after a colonoscopy.
What could go wrong
This is a small, early-stage trial with no phase designation. The supplement may work no better than placebo, and results may not apply to everyone.
