**Abstract**

The presence of *Candida* in the gut is normal, but an overproduction may lead to serious health problems due to an imbalanced gut, causing gut-related symptoms such as bowel movement changes, excessive gas, etc. Some diseases, such as Crohn's disease and ulcerative colitis, are associated with an overgrowth of *Candida* in the gastrointestinal tract. Several recent studies have shown that a prolonged candidiasis within the intestines is associated with *Candida* overgrowth syndrome or chronic fatigue syndrome. A healthy digestive system relies on a good balance of bacteria that live in the gut, and an important role in maintaining this balance is having the ingested type of food. *Candida* overgrowth can be prevented first of all by healthy eating patterns, as susceptibility is increased by a high-sugar diet and diabetes or nutritional deficiencies causing a dysregulated immune system. In general, *Candida*-associated conditions have a high impact on performance. Recent research has shown an increasing interest in the *Candida*-related conditions and diseases.
