Can the bad breath causes really include diseases?
While poor dental hygiene accounts for most cases of halitosis, bad breath can sometimes be a signal for an underlying medical condition. And even when you take “bad breath” out of the equation, breath can still demonstrate health issues: a slew of recent studies have used simple breath tests to screen for medical conditions.
But a fruity breath odor, or an odor similar to acetone (commonly used in nail polish remover) can also signify a serious complication in diabetic patients called ketoacidosis. When the body doesn’t have enough insulin, it instead uses fatty acids for energy, which produces acidic ketones, byproducts of fat metabolism. These acids, which include acetone, hydroxybutyrate, and acetoacetate, can accumulate in the blood and lead to a diabetic coma and death.
