Sadly many types. Officially diagnosed through Diagnostechs with ascaris, trichinella, toxoplasmosis. A LLMD diagnosed tricuria tricuris, another Dx'd lung fluke. From the initial parasite cleanse it was clear that I also had tapeworm.
How do many? I was on 43 weeks of Antibiotics in my 2011 pregnancy with GERD medicine which made my stomach acids nil (not killing off parasites). Then steroids and just a sad story thereafter to present....
Whatever you do make 100% sure you don't suffer from permeable intestines with parasites and take steroids. My doc always thought IBD but Ya....:those tests for Crohn's/UC were negative. Docs in America do not realize this seriousness of parasites.
