I was telling my friend at work about parasites and fatigue ect. She said when her brother was 6 he got rreally tired and did not want to play or go to school. He would get really sick and vomit any time he ate fat. His mom thought it was his liver so they got that checked out and his liver was healthy. One day a roundworm came out of him partially when he was on the toilet and he screamed. His dad came and pulled it out. It was about 18 inches and alive and tried to crawl back in when it partially came out. My friend says his fatigue went away immediately as well as his fat digestion problem. The doctor scolded the father for pulling it out b/c he said it could have injured an organ if it was attached to it.
