What are the white worms coming from your butt and how do you get rid of them?

Not unless you are infested with them... it's not healthy to have worms living in you.

The most common worm to live inside a human is the Threadworm (or Pinworm).

Threadworms are tiny little white worms, about 3cm long. The female worms lay their eggs in your gut which go down to the rectum (butt). These eggs are coated in a sticky white substance which causes the butt to get itchy, or tickly when the worms move. If you're a girl, then the female may move forwards and lay her eggs in your vagina.

In the UK, these worms are more likely to be on kids. When you itch your butt, sometimes people won't wash their hands and the next time you put your fingers in your mouth is when the worms under your nails will travel down your throat to your gut once again. This is a lifecycle.

Consult your doctor if you think you have worms. He'll give you a tablet which starves the worms to death.
