Discussion: Nail fungus and recurrent vaginal fungal infections in women often reflect an imbalanced gut flora prevalent in diabetes patients.

Nail fungus is not just a matter of hygiene in swimming pools and damp places that contact the feet, but is mainly a symptom of an unbalanced intestinal flora and very acidic intestines. It has an immense impact on the immune system. The gastrointestinal tract is the primary non-sterile internal system, thus forcing the immune system to fight relentlessly to prevent the overgrowth of pathogens.
