Parasites living creatures that enter our body and live off of our insides. They can enter our body through our mouth, nose, or skin. One study has found that over 95% of the world's population have parasites in their bodies. They may have come from uncooked or unwashed food, contaminated water, or through the air. When the organisms are swallowed, they move into the intestine, where they can reproduce and cause serious symptoms. Most doctors can not diagnose parasite symptoms as these symptoms could be caused by other things.
