What this trial studies

This clinical trial investigates the effects of Lactobacillus GG, a type of probiotic, on children aged 6-15 who suffer from functional abdominal pain disorders, such as irritable bowel syndrome. The study aims to determine whether this probiotic can alleviate symptoms and improve the quality of life for these children. Participants will be divided into two groups, receiving either the probiotic or a placebo, to assess the effectiveness of the treatment. The trial is designed to provide insights into the role of the microbiome in managing abdominal pain in pediatric patients.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce abdominal pain and improve the quality of life for children suffering from functional abdominal pain disorders.

How similar studies have gone: Previous studies have shown promising results with probiotics in managing gastrointestinal symptoms, suggesting potential success for this approach.
