Transient lactose intolerance in infancy.

Bartrop, R. W., and Hull, D. (1973). Archives of Disease in Childhood, 48, 963. Transient lactose intolerance in infancy. The clinical details of 100 infants with disaccharide intolerance secondary to a variety of bowel disorders were examined. Malnourished infants under 6 months of age were particularly at risk. The difficulty of establishing the relevance of sugar intolerance is emphasized. The analysis suggested that infants with troublesome, persistent diarrhoea under the age of 6 months, particularly those underweight, should be treated with a lactose-free diet, but that lactose might be introduced once the child is thriving and stools have returned to normal consistency.
