Candida is a widespread and often misdiagnosed condition that affects thousands of Americans. Headaches, depression, inability to lose weight, digestive disorders, skin rashes, sugar cravings, and sinus problems are all symptoms of a systemic yeast imbalance. A systemic yeast problem can lead to a weak immune system. Mold, antibiotics, steroids, high sugar intake, and stress are all potential causes for Candida overgrowth.
