Liver disorders affect children as well. There are over 100 types of liver disease that can afflict children. I am making mention of a few that are most common –

1. Chronic Active Hepatitis – This is a fairly common liver disease that affects children. It is quite similar to an allergic reaction. In this case, the cells in the liver are destroyed and get replaced with scar tissue. Why this happens is not understood.
2. Galactosaemia – This is a genetic disorder that is present at birth. It can lead to serious complications such as cirrhosis of the liver, cataracts and brain damage. What is known about the condition is that the patients do not have an enzyme that is needed to break down and digest the sugars present in milk. This leads to a build up of milk sugars in the liver and other internal organs.
3. Biliary Artesia – Children suffering from this disorder either have no bile ducts or the ducts are too tiny. Because of this, the liver fails to release bile and it results in cirrhosis of the liver and internal bleeding. It is a serious condition and is usually fatal. Children suffering from this disorder generally do not survive beyond the age of two.
4. Wilson’s Disease – This is again a genetic disorder where the anomaly leads to the accumulation of copper in the liver which causes brain damage and liver cirrhosis.
