Smelly breathing

Why would I have a bad smell coming out of my lungs

[Sunny602]

If it is definitely from the lungs, an abcess (abscess) can be very foul smelling. Other causes may not be stemming from your lungs...For instance, tooth abcesses or poor dental hygiene would cause a foul odor along with badly infected sinuses. I know that there are other causes....You really should get a good examination from a doctor, especially if you have other symptoms. Do you have other symptoms besides a foul odor such as pain, temp etc...?
