Pulling out a long thread-like substance when relieving stool may indicate intestinal parasites, or it may be food residue. Human infection with parasites does not necessarily show symptoms such as abdominal pain, bloating, etc., but when relieving the stool, the parasites can be discharged with the stool as a long thread-like substance. After careful observation, if the long thread-like material can move or wriggle, and the color is rice-white, flesh-colored, etc., it is usually suggestive of roundworms, tapeworms and other parasites. Long thread-like objects may also be found in the stool if the diet has recently contained high-fiber and other indigestible ingredients, such as beetroot and shredded bean curd. No special treatment is needed at this time. If you can’t recognize a long thread-like object in your stool, it is recommended that you consult a doctor in a timely manner, and have it clarified after completing the relevant examinations under the guidance of a medical professional.
