Prevalence of Lactose Intolerance in Children with Recurrent Abdominal Pain

Dr W. M. Liebman has reported an interesting study on lactose intolerance in children with recurrent abdominal pain (Pediatrics 64:43, 1979). His data suggest that lactose intolerance plays a contributory role in recurrent abdominal pain in children.

Recently I have performed an almost identical study on Danish children with recurrent abdominal pain with quite another result.1

Tolerance tests after oral lactose (2 gm/kg of body weight) were performed with parental consent on 50 children (22 girls and 28 boys, mean age 9.5 years) with recurrent abdominal pain and on 40 children (17 girls and 23 boys, mean age 9.6 years) without such pain.
