Re: this is not a "roundworm"!!!!!!!
Your pics are very clear and look exactly like the hundreds I have expelled. In the early stages of my infestation I had nice white translucent worms come out, but after that initial period they are all dead and degraded like the ones in your pictures. Mine also have the larger end, which I figured was just the head rotting and flattening, and also they have like a forked head with three lips, so that would make the head flare out when dead wouldn't it?
I posted pics a while back. They are not as close up and clear as yours, but looking at your toilet pics is exactly the view I have all time. There have only been a couple of others that looked like mine, and alot of the pics posted as possible worms don't look like worms to me.
I have also been puzzled by the pictures of
Ascaris on youtube and other sites, because mine are not round, they are flattened. But what else could they be? I really don't think mine or yours look like tape worms.
I have an appointment with a gastro doc soon. Maybe I will have an answer for us soon. I am hoping that during an endoscopy or colonoscopy a live worm can be found. I'm beyond being embarassed and I'm not crazy, I just want them gone. Good luck to you.
