Yes, it could be. It has been a guessing game for me the past 8 months. First we thought it was Giardia, then we thought it was yeast, then I passed a worm that looked similar to a Tapeworm so that is what I thought we had.
We have taken in numerous lab samples and all have come back negative. We even took in worms we had passed and the doctors would not even look at them. One doctor has at least tried to help by prescribing us Albenzadole and Praziquantel. He understands that the labs are very unreliable.
Next I am going to try Ivomectin. Maybe it will do the trick for me. My wife still seems to have killed her parasites. Her stomach is back to feeling normal. Although we have kinda forgot what normal was. She simply took 9oo mg of Praziquantel. It was prescribed by the doctor. I can tell the prescribed stuff is more potent than what we order online but it is very expensive.
