Candida Albicans Overgrowth hypothesis

Candida albicans overgrowth may be caused by antibiotics after an infection. This may inhibit the carbohydrate metabolism, activating the immune system, causing a real sense of illness and fatigue. Treatment is challenging, and includes dietary suggestions.

Theory
Candida albicans overgrowth could be originated to an antibiotic treatment after an infection. The candida albicans overgrowth in the stomach and bowel might be a root cause for reduced ability to convert glucose to cell energy, influenced by the amino acid tryptophan in the metabolism. This may activate the immune system, causing sense of illness and fatigue. Treatment of the candida albicans overgrowth is challenging and a specific diet is suggested for treatment during 3-4 months.

Evidence
Candida albicans overgrowth in the stomach and bowel might be a root cause for a metabolic trap leading to reduced ability to convert glucose to cell energy, similar to the Warburg effect. It is also suggested that candida albicans overgrowth could be caused by an antibiotic treatment after an infection. In addition, it is also mentioned that the amino acid tryptophan could be inhibited by candida albicans overgrowth. . This may activate the immune system, causing sense of illness and fatigue. Treatment of the candida albicans overgrowth using probiotics or antimycotics was not effective, and a specific diet (low carbohydrate, fat rich etc.) was suggested for treatment during 3-4 months. .
