What Causes Bad Body Odour In The Places Where Air Doesn T Reach?

I am 69 and I went to the doctor because I have symptoms of IBS . Well, she didn t say why, but I think my age has something to do with the new meds out there. So she said, no flour products, wheat, crackers, that I have a fungus like in my stomach or intestine. I have odors in places where the air does not hit. I could use a fungus type cream, and then it gone for a few days. So she told me to take Cat s claw. Well, finally I had so money to by it and I been on it for 3 days. I had diarrhea before but really bad and could not hold it. many accidents. So I been on Cat s claw. What will it do for me? I still have diarrhea but not as bad as before. Thank You P Monsivais
