It could cause such problems without going fungal. I have had malabsorption problems and soo many different issues when there was just massive dysbiosis in my intestines...yeast overpowering the good bacteria. But then soon enough the fungal state pierced into my intestines and caused severe leaky gut...that's when my whole body just gave out...when you're in that state...it is soo hard to get back to normal. So if one is able to catch themselves before it goes fungal....then great!
