[|Human|] my 7 year old son had red blood in his stools for 5 days this week. On the 4th day he had a rectal exam and it caused some pain possibly as if a fissure or hemmoroid. the next day he passed more blood and a white ellipsoid object about 1 x 3/4 and covered with strings of blood as if it was a tooth ripped out of a socket, except it was 2mm length strings spaced about 5mm apart all around the object. There was fiberous stuff in the stool that looked like orange juice pulp, but he gets that frequently and may have had shredded wheat for breakfast that day. He has not bled since, but we are going to get a stool sample and bloodwork on Monday. I am concerned because his bowels have not been normal since he was 3 and threw up in a McDonalds with a stomach bug which we thought may have been food poisoning. He has a history of a prolapsed rectum in 2008 or 2009 (with a negative breath test) and no repeat prolapse. Any thoughts on what this could be? I found pictures online of mucous that it could look like, but with all of the blood it appears it was attached at some point.
[|AI|]  Causes of red blood in stools may be due to hemorrhoids, fissures, ulcerative colitis, intestinal infections, Lower intestinal bleeding etc. Sometimes hard object seen in a children stools may be toothed, plastic beads, small round toys etc. which child may have accidentally ingested. Investigations like USG abdomen, colonoscopy, stool exam, X-Ray abdomen etc. needs to be done as soon as possible to find exact cause.
