Current status and prospect of diagnosis and treatment of neonatal lactose intolerance
Lactose intolerance refers to the poor absorption of lactose caused by insufficient number or low activity of lactase,which leads to one or more gastrointestinal symptoms.Newborns are mainly develop-mental and secondary lactase deficiency,with various clinical symptoms,which are easy to be missed and mis-diagnosed.Neonatal lactose intolerance is often diagnosed by fecal reducing sugar and pH determination and urinary galactose determination,but there are still many hospitals that have not carried out related inspection projects.Although there is currently a lack of specific guidelines for neonatal lactose intolerance,but in the context of promoting breastfeeding,reducing the abuse of special milk powder,and rational use of efficient,high-quality lactase is particularly important.In addition,a series of problems involved in the diagnosis and treatment of neonatal lactose intolerance in China need to be further explored.How to find a balance point in the treatment of lactose intolerance will be a direction for future research.
