There is no such thing as the nemesis of roundworms. Roundworm infection requires regular treatment, such as the use of drugs, surgery and good hygiene habits. 1. Use of drugs: Mebendazole and other anthelmintics can be used as prescribed by the doctor, which can kill roundworms by directly inhibiting the intake of glucose by the worms, resulting in the worms not being able to survive in the body. 2. Surgery: When roundworms are active in the intestinal system, some of them may lead to blockage of the bile ducts. At this time, surgery should be considered for deworming to remove the worms from the bile ducts and restore the bile ducts to avoid the impact on the normal flow of bile. 3. Adopt good hygienic habits: some patients with recurrent roundworm infections can be caused by poor dietary hygiene control. After deworming, they need to develop good hygienic habits, wash their hands more often, and control the source of roundworm infections. Patients with roundworm infection are advised to go to regular hospitals, consult a professional doctor, and cooperate with the doctor to complete the relevant examinations, so as to avoid blind treatment and delayed treatment resulting in adverse consequences.
