Symptoms & Signs

Bad breath, medically known as halitosis, is a common problem. Bad breath is usually simple and preventable. Dietary factors as well as tobacco and alcohol use may all be factors in causing bad breath. Poor oral hygiene or mouth infections can also be causes of halitosis. Infections in the lungs, sinuses, or airways can also cause bad breath due to the presence of nasal secretions that may drain into the mouth. Coughing up sputum from lung infections can also cause bad breath. Dry mouth (xerostomia) can be a side effect of certain medications, increasing the tendency to develop bad breath. Certain chronic diseases that severely restrict liver or kidney function may also alter the odor of the breath.
