I have a bad smell coming from my nose when i exhale. it comes and goes randomly. it becomes more pungent when i am exercising. i notice that if i don't eat that the smell isn't as bad when i do. i feel that the smell is coming from my throat?

Hello. Abnormal smells may be coming from nasal/sinus infection or from possibly food particles that become embedded within tonsil tissue. I’m assuming you haven’t had your tonsils removed. Saline nasal irrigation then follow with Flonase. I’d recommend doing this twice/day. Also gargle with water after every meal. This combo will help keep the airway mucus membranes clean and free of infection.
