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.
