Patient's question:
The child of my cousin was born. At first, the child often experienced nausea and vomiting while breastfeeding. A careful examination revealed a case of lactose intolerance. Hello, what are the differences between galactosemia and lactose intolerance?Doctor's answer:
Galactosemia is a disease caused by a congenital genetic defect, primarily resulting from the encoding of 1-galactose-1-phosphate uridyltransferase. The deficiency of this enzyme leads to the accumulation of galactose and its hydrolysis products in the body, causing severe symptoms such as hepatomegaly and cataracts. These are two diseases with different etiologies. It can be said that lactose intolerance is primarily acquired, while galactosemia is congenital.
