Causes of soiling
Constipation is the most common cause of soiling. When children are constipated, it is difficult and painful to pass the hard stool. Fecal liquid leaks around the hard retained stool, and out of the anus.
Some children, especially toddlers, will start to hold their stool, because they are not ready to toilet train, or because of painful bowel movements due to constipation. This can start a cycle of holding, constipation and soiling.
Another cause is illness. Children with
diarrhea may have a hard time controlling their bowel movements. This usually goes away when the diarrhea improves.
Sometimes, soiling is associated with emotional or behavioural difficulties.
Some very rare neurologic or spinal cord diseases can cause soiling. These children may also have peeing accidents, and clumsiness or weakness of their legs.
