Bad breath, also called halitosis, is typically caused by bacteria that grow in your mouth. Short-term bad breath may be associated with tonsillitis, gastroenteritis,acid reflux, diabetic ketoacidosis, or sinus infection. Chronic halitosis may be caused by poor oral hygiene, gingivitis (gum disease),oropharyngeal infections or a dental abscess.
Bad body odor is caused by smell of bacteria growing on the body. These bacteria multiply rapidly in the presence of sweat, but sweat itself is almost completely odorless. Body odor is associated with the hair, feet, groin (upper medial thigh), anus, skin in general, armpits, genitals, pubic hair, and ears.
