Irritable Bowel Syndrome and Lactose Maldigestion in Recurrent Abdominal Pain in Childhood

Abstract

The mean age of the 59 boys and 87 girls was 9.5 +/- 3.0 years. Children with IBS and lactose maldigestion had more frequent abdominal pain than children without these conditions, but they required less medication for relief of symptoms. CONCLUSIONS. Lactose maldigestion may be a contributory factor in children with IBS, and lactose avoidance in these patients may reduce medication use to relieve symptoms.
