I started to suspect the small intestine since my symptoms actually would indicate SIBO (small intestine bacterial overgrowth). And also because it seems that the colon isn’t the problem. This conclusion is based on the results of a colonic I had out of desperation to see if it would lessen the baby bump. It didn’t. Apparently there was no yeast coming out. But yes, she only uses water, so who knows. However I am not going back there as it’s quite expensive and more or less ineffective.
And yes, I also found out the hard way that starving is not the way to deal with this. At the time I really thought I was doing the right thing in order to heal but ended up messing up my health even more. Oh well, you live and learn, I guess.
