Why does my breath smell like poop?
The common causes for your breath to smell like feces are sinus and respiratory infections (such as bronchitis, viral colds, strep throat), poor oral hygiene (infrequent cleaning, chronic dry mouth, oral infections, smoking or chewing tobacco), Gastroesophageal reflux disease, abscessed tooth, prolonged vomiting (> 24 hours) and bowel obstruction.
