My 4 year old brother was pooping and he said he was having trouble so my mom went in to help him and he had pushed out some of his insides confused?

Rectal prolapse: It sounds like your brother has a rectal prolapse. In children the rectum can be pushed back into place. But it will be necessary to treat your brother's constipation with diet and medication.

Prolapse: What you are describing soiunds like rectal proplapse. This is when the rectal lining everts with excess pressure as in constipation. Treat the constipation and it should resolve. If it persists, he may need a seat chloride test to rule out a genetic cause, but this would be rare. cystid fibrosis should be ruled out if prolapse persists. this can be done with sweat chloride test.

Your Mom: Need to take your brother to the emergency room, possibly rectal prolapse from chronic constipation!
