An overgrowth of yeast can occur due to poor diet, early antibiotic use, and a variety of other reasons. This overgrowth of yeast can produce abnormal toxic metabolites which can cause or worsen behavior disorders, hyperactivity, and aggressiveness. These can also affect energy levels and immune function. Yeast can attach to the intestinal wall and lead to "leaky gut syndrome", which can exacerbate food allergies, impede absorption, and create multiple nutrient deficiencies. Our office offers systemic yeast testing as a part of our food allergy testing or we can order a more specific yeast test called an Organic Acid test. Once yeast overgrowth is diagnosed, dietary programs are established and targeted nutrition is utilized to destroy the yeast and restore health.
