Systemic Diseases Causing Bad Breath

 

When you visit the dentist, he will pay attention to any unusual breath. Sometimes it smells like bad home care, but it can signal that the patient has a systemic disease. The dentist should pick up on this and refer you to your medical doctor.

According to an article on “halitosis” in Wikipedia,

“There are a few systemic (non-oral) medical conditions that may cause foul breath odor, but these are extremely infrequent in the general population. Such conditions are:

  1. Fetor hepaticus: an example of a rare type of bad breath caused by chronic liver failure.
  2. Lower respiratory tract infections(bronchial and lung infections).
  3. Renal infections and renal failure.
  4. Carcinoma.
  5. Trimethylaminuria(“fish odor syndrome”).
  6. Diabetes mellitus.
  7. Metabolic conditions, e.g. resulting in elevated blood dimethyl sulfide.[6]

Individuals afflicted by the above conditions often show additional, more diagnostically conclusive symptoms than bad breath alone.”

Studies done in Canada by Yaegaki and Coil appear in an article “Halitosis: A mirror of systemic and oral health.”   Check out the article for the table of systemic diseases and the nature of the halitosis.
