Patient discussion about parasitism

Q. is an Amoeba dangerous?? and how can i get rid of it? my son is in Peru, he called and told me he got an Amoeba..i have no idea if it's dangerous or not, and how to get rid of it. and what kinds of food he needs to avoid.I'll appreciate help!

A. oooo...an Amoeba is a nasty one...but not so dangerous! it's a one celled parasite which gets into your body if you eat in restaurants that the cook doesn't wash hands after going to the bathroom..it multiplies in your intestine and makes you diarrhea like hell. but if you'll treat it right it will go away as nothing happened. if you don't it can give you liver cyst. and that's not good. he should see a Dr.
