  • Breath screenings can detect stomach cancer.
  • Breath tests can help diagnose lung cancer.
  • Breath tests can easily identify heart problems.
  • Gum problems indicate diabetes.

Your breath says much more about you than just your personality and that is why a quick breath check exam will help you in not only saving you from embarrassing social situations, but also your life!

Bad Breath Causes

In a study published in the journal Gut, it was revealed that a latest breath test technology may detect stomach cancer in its earliest stages. And it does not end here! An underlying health condition does not always make your mouth stink away. Even the freshest of breaths can be examined for various health conditions.

So, here we give you 5 ways in which your breath can indicate health problems.

Stomach Cancer

Tests that are generally used to screen stomach cancer are invasive in nature. Therefore, a routine screening  to check for cancer is very uncommon. However, this could change with the introduction of a new breath test technology called nanoarray analysis, which aids the identification of levels of certain compounds that may be linked to the condition.

Lung Cancer

A 2013 study vouched for breath tests for diagnosing lung cancer purposes. These breath tests could easily replace the traditional biopsies and ultrasound scans because they are a lot cheaper and non-invasive.

Heart Failure

A paper published in March 2013 showed how simple it was to identify patients suffering from heart failure using a breath test. The paper was published in the Journal of the American College of Cardiology.

Bad Breath Causes


If your diabetes has gone awry, there are high chances that you will suffer from gum diseases and dry mouth. A stable blood sugar level strengthens the body against bacteria that can cause infections that damage gums. It is these infections that can cause foul breath.

Kidney Failure

Seafood isn’t always the culprit behind your fishy breath. If your mouth smells like fish, urine or something similar to ammonia, it could be an indication of kidney failure.
