Thank the lord there is someone here who is experiencing the same thing!
I have all the same symptoms as well. Acne, eat a lot but lose weight, dandruff, constipated all the time, bloated stomach, and it keeps going on. I have not had tests done like you've had though. But I am not going to bother because its a waste of money. My doctors laugh at me too! They think something like candida or parasites is impossible!
And again, this has happened in the last year or so. I am 22 years old and a male. I am skinny skinny and never was this skinny.
I however have seen some results from these candida capsules ive been taking that contain Oregano Oil and all that junk. I noticed a slight difference and I am pooping out string! So maybe I need to amp up the dose?
