Lactose Intolerance | Paediatrics Healthcare

Lactose is the primary digestible carbohydrate found in breastmilk. Healthy term infants are born with sufficient lactase enzymes which are required to digest lactose. Infants become intolerant of lactose when there is a deficiency of the lactase enzyme which is responsible for breaking down lactose into its two components, glucose and galactose, before absorption.1 Primary lactose intolerance generally does not manifest in children before 5 years of age.2 Lactose intolerance in young children is generally linked to underlying gut conditions such as viral gastroenteritis, coeliac disease or Crohn’s disease.2 Therefore, lactose intolerance in young children is mostly transient and improves with treatment of underlying gut pathophysiology.2

Approximately 70% of the world’s population have primary lactase deficiency.2  The percentage of lactase deficiency prevalence varies according to geographical areas, ethnic groups, age and consumption of dairy products in the diet.1Different diagnostic techniques and management approaches may be utilised by the healthcare professionals during periods of lactose intolerance. Breastfeeding remains possible for the majority of lactose intolerant infants.3,4
