Halitosis

Considerations

Some medical disorders will produce specific, characteristic odors to the breath.

• A fruity odor to the breath occurs as the body attempts to get rid of excess acetone through the breathing. This is a characteristic sign of ketoacidosis (such as diabetic ketoacidosis), a potentially life-threatening condition.

• A fecal odor to the breath (the breath smells like feces) can occur with prolonged vomiting, especially when there is a bowel obstruction. It can also occur temporarily if the person has a nasogastric tube in place (a tube placed through the nose or mouth to the stomach to drain the stomach contents).

• The breath may have an ammonia-like odor (also described as urine-like or "fishy") in people with chronic kidney failure.

Common Causes

If previously normal breath turns into halitosis, causes could include:

• Food or beverages consumed (such as cabbage, garlic, raw onions, or coffee)

  • Often (but not always) there is a white, yellowish, or bloody discharge from one nostril
• Drugs
• Paraldehyde
• Triamterene and inhaled anesthetics
• Insulin - injection

• Acute necrotizing ulcerative gingivitis
• Acute necrotizing ulcerative mucositis
• Acute renal failure
• Bowel obstruction (can cause breath to smell like feces)
• Bronchiectasis
• Chronic renal failure (can cause breath to smell like ammonia)
• Diabetes (fruity or "sweet chemical" smell with ketoacidosis)
• Esophageal cancer
• Gastric carcinoma
• Gastrojejunocolic fistula (fruity-smelling breath)
• Hepatic encephalopathy

Home Care

Use proper dental hygiene (especially flossing), and remember that mouthwashes are not effective in treating the underlying problem.

Fresh parsley or a strong mint are often effective ways to fight temporary bad breath. Avoid smoking. Otherwise, follow prescribed therapy to treat the underlying cause.
