Hello, my 6 year old daughter has a long dark string that comes out from her rectal when she has a bowel movement. It resembles a piece of thread. Should I be concerned or has she simply swallowed a piece of string. This is the 2nd time this has happen within the last 2 weeks.
Your daughter is suffering from worm infestation. Those long thread like things are worms. Consult your doctor and ask for stool examination and deforming medications like Albendazole.
