Candida albicans is a normal resident of human mucosa and in optimal concentration, they are in symbiotic balance. Weakening of the hosts protective barrier with  inadequate immune function leads to overgrowth of Candida, the release of toxins and the appearance of symptoms affecting various organ systems of the digestive system (bloating, constipation and/or diarrhea, difficulty digesting food, bad breath, weight problem, water retention, irritable bowel syndrome), respiratory system (persistent dry cough, sinusitis, ear infections), musculoskeletal system (joint pain, arthritis, athletet’s foot) and metabolic, mental disorders, frequent headaches and migraines. To diagnose fungal infection, Analiza offers the possibility of serological testing of IgG and IgM antibodies to Candida albicans, with medical and nutritional advice related to detecting the causes of overgrowth, changes in diet and the use of natural antifungal agents.
