4Prolonged Vomiting
The presence of saliva in the mouth prevents some extreme odors since it helps to clean the mouth. Vomiting, however, dries the mouth of saliva, increasing the chances of bad breath. Prolonged vomiting, on the other hand, results in dry mouth and severe bad breath. What’s more, vomiting due to bowel obstruction usually erupts with poop smell breath. [5]
