Lactobacillus reuteri is one of a few naturally occurring strains of lactobacilli colonizing the human colon. In fact, L. reuteri is found in the digestive tracts of many animals, and is also present in many meats and milk products. It is passed from healthy mothers to their newborns via breast milk. When it colonizes the gut, L. reuteri supports the immune system and helps prevent infections.
The study included 44 infants with chronic constipation, marked by two or fewer bowel movements per week, hard bowel movements that were large and painful to move, and the presence of a large mass of feces retained in the rectum. The infants were at least six months old, had been weaned, and were being fed formula. Half of the babies were given five drops of a probiotic liquid providing 100 million colony-forming units of L. reuteri per day for eight weeks, while the other half received placebo. Parents kept track of bowel movement frequency, stool consistency, and episodes of inconsolable crying.
At the end of the study, comparisons were made between the babies receiving the probiotic and placebo:
Unexpectedly, episodes of inconsolable crying increased in both groups during the study, and this change was slightly more pronounced in the probiotic group.
The findings suggest that L. reuteri can be effective for increasing stool frequency in chronically constipated infants. “On the basis of our results,” the study’s authors said, “probiotics as a natural, safe, well-tolerated treatment may provide a simple and attractive way to treat infantile functional chronic constipation.” The reason for the increased crying seen in both groups in this study remains elusive.
Here are some additional measures you can take if your baby suffers with constipation:
