A small study followed 69 children with chronic constipation through a 12-week trial of four phases (three weeks per phase).
Constipation resolved within 5 days in 27 children in phase 2 (when cow’s milk was removed). It returned in phase 3 (when cow’s milk was reintroduced), and disappeared again in phase 4 (when cow’s milk was removed the second time). No other dietary changes were made.
Although small and not blinded, the fact that constipation returned when cow’s milk was reintroduced is compelling.
PositiveTip: The simple intervention of removing dairy milk is certainly worth a try if your child suffers from chronic constipation.
