Welcome to HealthcareMagic. Bad breath
is also called halitosis
. The smell is due to gases produced by the action of certain bacteria on protein and other substances. These bacteria may be present on your tongue, in your mouth, gums , nose, tonsils, esophagus
or stomach. Itâs advisable to consult your otorhinolaryngologist for the sinus examination, dentist
for oral care, pulmonologist for lung examination and a gastroenterologist for upper GI examination.
Hope it helps you. Regards.
