Cleaning parasites from the body depends on the type of parasite and the severity of the infestation. Generally, if the infestation is mild, medication is the most common treatment. For example, anthelmintics, such as mebendazole, are used to treat roundworm, hookworm, and whipworm. Antiprotozoals, such as metronidazole, are used to treat amoebas and giardia. Antibiotics are usually used to treat bacterial parasites, such as those that cause trichomoniasis.
In more severe cases, surgery may be required to remove the parasites. This can involve removal of the parasites from the intestines or other affected organs.
In addition to medication, dietary changes might also be recommended to help rid the body of parasites. These can include eating a diet high in fruits, vegetables, and whole grains, avoiding processed foods, and avoiding sugar and alcohol.
Finally, good hygiene is essential for preventing re-infestation. This includes washing hands before eating and after using the bathroom, avoiding contact with contaminated water or soil, and keeping household surfaces clean.
