What Is Post Nasal Drip?
Reviewed: Dr. Gromatzky
8. Bad Breath
Many infections will cause bad odors. This is because bacteria produce often foul-smelling gases as a by-product as they are metabolizing their food. Depending on where in the body the infection is, it can cause the patient to have bad breath.
Post nasal drip is sometimes caused by infections and, as the mucus drips down the back of the throat, it will often take a lot of the bacteria and odor with it. Thus, depending on the underlying cause, some patients with post nasal drip will also develop bad breath that is difficult to make go away even with regular brushing.
