Over growth of Candida Albicans and other fungus related organism.
Treatment is usually long term.
Three months to one year depending on the time necessary to establish the normal bacterial fungal symbiotic relationship. Candida lives on sugars and starches therefore the most important dietary change is to eliminate these as much as possible. Yeast, molds and fungi cross-react in the allergic response. So to avoid allergic reactions to yeast and molds these must be eliminated from the diet to control the symptoms. Eating these foods wouldn't undermine your efforts to eliminate the candida, but they could make you feel miserable.
