Symptoms of stomach fungus include rectal itching, bloating, gas, intestinal cramps, and diarrhea or constipation, according to Dr. Mark Hyman. Patients may also experience chronic fatigue, general malaise, loss of energy and a decreased libido if they have a 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.
