<s>[INST] Hi, may I answer your health queries right now ? Please type your query here...I have just found a worm in the toilet after my 3 year old had passed urine only. it was about 3 to 4 inches in length and very thin not even a milimetre. it was black in colour. She hasn t shown any signs of troubles going to the toilet and with her tummy. Thanks [/INST] Hi, It is quite unlikely for worms come out of urine. I guess your kid is a girl-in girls, worms coming out of anus can crawl in and around to reach vulval area, which is then flushed out while passing urine. This can happen in boys also, though more uncommon. It would be more helpful if you can send a picture of the worm. I suggest you to give albendazole tab 400 mg at night once(or 10ml of suspension) if not given in past 6 months. There is a type of worm infesting bladder, but usually we can't see them with naked eyes. Hope I have answered your question. Let me know if I can assist you further.  </s>
