Gut Dysbiosis, Leaky Gut Syndrome, Candida, viral
gastroenteritis (stomach flu) food poisoning and parasites are all suspect.
Most of these have something in common, which is bacteria overgrowth.
Very low carb diet, peppermint oil supplements (enteric coated caps)
and high quality probiotics usually help in such cases.
Also Extra Virgin Coconut Oil 2T daily will help as it is anti-fungal, anti-parasitic, anti-viral and anti-microbial.
