Yes.
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.

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.
Doctors found that among the non-smokers, lung cancer was accurately identified in 128 subjects and misdiagnosed in only five. Among smokers, they correctly identified 114 people as having lung cancer, misdiagnosing five. Both smokers and non-smokers with bad breath can be at risk.

Researchers were able to use a simple breath test to identify patients suffering from heart failure, according to a March 2013 paper published in the Journal of the American College of Cardiology.
Cleveland Clinic researchers collected breath samples from 41 patients. Twenty-five were officially diagnosed with
“acute decompensated heart failure.” Sixteen patients had other cardiovascular conditions but showed no signs of heart failure.

The kidneys are responsible for removing toxic chemicals from the blood by creating urine.
In kidney failure, also known as end-stage renal disease, the kidneys become so damaged that they are no longer able to filter waste products and toxic chemicals from the blood.
When this happens, the dangerous toxins and waste not discharged from the body accumulate and affect nearly every part of the body.
A fishy breath odor can occur when kidney failure affects the respiratory system and causes breathing problems.
Digestive conditions can delay or prevent food from processing efficiently from the stomach.
When food doesn’t move through the digestive system, it can start to decay.
Small amounts of undigested food may even regurgitate and cause bad breath. Dentists may also detect GERD in patients when they notice an inflamed red throat and acid erosion in the teeth.
