Gut ecosystem imbalances are the root cause of any symptoms of candida. When the candida is under control in the gut it should not produce any symptoms elsewhere. Our immune system begins with our good flora in our gut and is backed up by our white blood cells. I think some people concentrate on restoring white blood cell function when they still have gut microbiome imbalances. It can become very complicated once someone loses that balance. There are tons of people that have heavy metal toxicity or just toxic in general and have minimal candida symptoms. The reason why is that their gut ecosystem is still balanced. Scientists are just recently discovering that the cells in our gut outnumber the rest of our cells by a 10:1 ratio. It's unfortunate that the human body does not have a organ in the gut to churn out good flora when an imbalance occurs. When the majority of our immune system is in our gut.
