What Are the Symptoms of Stomach Fungus?

Patients with stomach fungus may suffer from irritable bowel syndrome, toenail fungus, psoriasis or eczema, explains Dr. Hyman. A sensitivity to allergens, chemicals or foods is possible, as well as cravings for foods that are rich in yeast or carbohydrates. A stomach fungus that affects the immune system may provoke allergies, sensitivity to chemicals and low functioning of the immune system.
