Does digestive tract odor cause bad breath?

No. these are two separate processes. Bad breath or halitosis is caused by mouth bacteria which dont have anything to do with the lower GI tract which is essentially separated from the "lower" GI tract by the acid within the stomach. For bad breath I recommend brushing your tongue daily and seeing your dentist.
