I went in for a colon hydrotherapy treatment today, and the Dr. told me that I have fluke, yeast, and amoeba infestations. She said that some of the flukes are a few years old (2-3 inches long). My assumption is that the reason these are that yellow color is that they died a while ago, but remained inside of me. I am trying not to go crazy thinking about all parasites crawling around inside of me right now.
I feel much better after the treatment, and I went down a whole size in jeans due to losing the gas in my stomach.
Here are some other pictures I took before I had the treatment if anyone else is trying to ID.
