Worms in the Toilet: Should you Go to the Doctor?

On two recent occasions in the last week, a reader found a worm in her toilet. She found the worm after she used and flushed the toilet in both instances. The worm in the toilet is quite small – it is only about a half an inch long (about 1.5 centimeters) – and it has a white and grey body.

In the meantime, she asked us to weigh in the matter, hoping that we can identify the small worm in the toilet she found.
