Determining whether a child’s poor liver function is dangerous or not depends on the specific cause of the poor liver function and the degree of liver function. First of all, if a child’s poor liver function is caused by an acute infection, such as a bacterial infection or a viral infection, the elevation of liver enzymes due to a temporary infection and the elevation of liver enzymes is relatively mild. In this case, the child is in good spirits and does not have significant jaundice and is generally not at risk. The next dangerous situation is if the child’s liver function is poor, caused by cirrhosis or biliary atresia, etc. The child’s elevated liver enzymes are also very obvious, and the child’s mental state is poor, even with obvious symptoms such as jaundice, which is more dangerous at this time.
