The term "yeast overgrowth" refers to an imbalance in the levels of yeast present within a person's body. This can occur when there is an excessive growth of Candida, which is a type of fungus that naturally lives on our skin and in our gut. When this balance is disrupted, it can lead to various health issues such as digestive problems, fatigue, brain fog, mood swings, and other symptoms associated with yeast overgrowth or Candida overgrowth syndrome (COS). The exact cause of the imbalance may vary from person to person but common factors include antibiotic use, stress, poor diet, hormonal changes, and a weakened immune system. Treatment typically involves addressing the root causes through lifestyle modifications such as improving gut health with probiotics, managing stress levels, and following an anti-Candida diet that limits sugar intake and promotes nutrient-dense foods.
