The main causes of white stools in children are due to several factors: first, symptoms caused by children with biliary atresia. If a child has biliary atresia, it can cause low levels of bilirubin in the intestines, resulting in white stools, typically clay-like stools. In this case, the child needs to be treated with surgery or even a liver transplant. Secondly, it is caused by children taking milk and other dairy products. If the child is mainly drinking breast milk or infant formula, the child may also have white stools due to indigestion. In this case, children can be given digestion-promoting medications to ease the problem, such as the application of pepsin.
