The following could be a cause of rectal prolapse:
-Straining in constipation
-Straining in urinary obstruction
-Prolapsing hemorrhoid or polyp
Direct injury to to anus may also be a factor and most affected children may be healthy with no obvious cause for the disease.
Therefore, there is a need to always present to a hospital on time though majority recover spontaneously without treatment. Most children suffering from rectal prolapse respond to non-operative measures.
