My father used the bathroom i went in the bathrm after him and seen 2 white worms in the toilet about a inch long maybe a little bigger please help!

Worms: Has he lost any weight recently? Traveled anywhere out of the ordinary? Regardless, take him to see his doctor & get stool studies (if you can bring in a worm, that would be extremely helpful although i know that sounds disgusting). He should get diagnosed & treated to prevent spread of worms elsewhere in his body. In meantime, good hygiene is a must.
