Background: Functional abdominal pain (FAP) is one of the most common diseases, and large percentages of children suffer from it.
Objectives: The purpose of the study was to evaluate the effect of
Lactobacillus reuteri
in treatment of children with functional abdominal pain.
Patients and Methods: This study was a randomized double-blind placebo-controlled trial. Children aged 4 to 16 years with chronic functional abdominal pain (based on Rome III criteria) were enrolled in the study. They were randomly divided into two groups, one receiving probiotic and the other placebo.
Results: Forty children received probiotic and forty others placebo. There were no significant differences in age, weight, sex, location of pain, associated symptoms, frequency and intensity of pain between the groups. The severity and frequency of abdominal pain in the first month compared to baseline was significantly less and at the end of the second month, there was no significant difference between both groups compared to the end of the first month.
Conclusions: This study showed that the severity of pain was significantly reduced in both groups. There was no significant difference in pain scores between them. The effect of probiotic and placebo can probably be attributed to psychological effect of the drugs.
