What are other signs and symptoms of c.diff besides diarrhea? what happens if gone untreated/undiagnosed?

Normal: About 3% of healthy people have C diff in their intestine. Just having C diff is not a disease. If you you do not have diarrhea, you do not have meaningful C diff infection. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
