You may have heard that colonics get rid of parasites.
Sure... maybe they will flush some out, but if you don't get rid of all of them, then they can continue to multiply. Therefore, I would not rely upon colonics to get rid of parasites.
I say this from experience because I went on a mission trip & was told by the leader's wife (who was a registered nurse) that the children had parasites. I thought to myself, I know how to cleanse so I will just love those children & hug them, rather than run away from them. I bought parasite cleanses from the health food store & from alternative doctors, along with fasting & colonics, but it did not rid me of my parasites. I also learned that the longer you keep parasites inside of you, it is possible they can do more damage to your body.
Long story short, I went to a doctor who specializes in parasites & he got rid of them very easily. Please...if you suspect that you have parasites, save your money & go see a doctor that specializes in parasites...like my doctor. See below to find a physician that can help you. Then you won't have to talk about your parasites anymore. Yaaaay!!!

A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Some parasitic diseases are easily treated and some are not. The burden of these diseases often rests on communities in the tropics and subtropics, but parasitic infections also affect people in developed countries, including the USA.

Parasitic diseases are diagnosed and treated every day in the United States. Some are common and some are very rare, found only in travelers or immigrants from areas where the parasites are common. Diagnosis is sometimes difficult and may require a specialist (see "How To Find A Physician" below).

Where can I find a Physician?

To find a physician familiar with diagnosing and treating parasitic infections, consider the following:

1. MY FIRST CHOICE would be to find a doctor who specializes in parasites on The American Academy of Environmental Medicine website. http://aaemonline.org/
2. Contact a member of a tropical medicine society or association.

   Examples of such associations include:

   • The American Society of Tropical Medicine and Hygiene: http://www.astmh.org
   • The International Society of Travel Medicine: http://www.istm.org

   Note: Not all physicians are members of associations or societies. Often a member of such a society is referred to as a "diplomate."
