What Serious Conditions Cause Bad Breath?

Runny nose, respiratory and tonsil infections, sinus problems, diabetes, liver and kidney issues, and certain blood disorders can all lead to bad breath. In rare cases, halitosis may be a sign of cancer or other serious medical conditions, such as metabolic disorders. The most common cause of bad breath, however, is poor oral hygiene. Without proper brushing, flossing, and dental cleanings, bacteria can accumulate in the mouth and cause a range of oral health issues, including halitosis, tooth decay, and gum disease.

Respiratory tract infections such as the flu, bronchitis, and sinusitis are also common causes of bad breath. When these infections break down or inflame the tissues of the respiratory system, they can trigger the production of cells that feed on bacteria and mucus. If bad breath is due to poor oral hygiene, dental cleaning and better oral hygiene at home are likely to help. It can be difficult to assess your own breath smell, so it's best to ask a close friend or family member for confirmation.

If your dentist doesn't find any oral health problems, such as tooth decay or gum disease, your primary care doctor can determine if another condition is causing halitosis. Tests can be performed to confirm the presence of halitosis by measuring the intensity of bad breath on a predefined scale and using instruments to detect specific compounds related to halitosis. If halitosis is a symptom of another condition in another part of the body, your GP can help you with the proper diagnosis and treatment. Fortunately, most cases of bad breath can be eliminated by treating the underlying health condition.

Therefore, it's no surprise that most cases of halitosis are associated with poor oral hygiene, gum diseases such as gingivitis and periodontitis, and dry mouth. Some people worry too much about their breath even though they have little or no smell in their mouths, while others have bad breath and don't know it. Because it's difficult to assess how your own breath smells, ask a close friend or family member to confirm that you're concerned about bad breath. The good news is that halitosis can usually be eliminated by treating the underlying health condition.
