The human body cannot eliminate roundworms on its own. Adult roundworm parasites are parasitized in the human small intestine and can cause ascariasis. The parasite will also multiply in large numbers during its parasitization in the intestines, and if left untreated, complications such as roundworm intestinal obstruction will occur, so the human body cannot eliminate roundworms on its own. Ascaris lumbricoides larvae can migrate in the human body, children are infected due to ingestion of infected stage eggs, mild cases are mostly without obvious symptoms, ectopic parasites can lead to complications such as biliary ascariasis, and serious cases can be life-threatening. If there are roundworms in the body, you can follow the doctor’s instructions to take some anthelmintic drugs for treatment, such as bis(hydroxynaphthyl)thiopyrimidine granules, but need to be used under the guidance of a physician. It is recommended that patients with roundworms in their bodies consult a doctor in a timely manner and take medication regularly under the guidance of a physician to avoid delaying their condition. The medication should be used under the guidance of a doctor.
