Your doctor wants to smell your breath. What it could reveal...

The next time you visit your doctor he or she might want to smell your breath...

It turns out our breath can be a valuable low-tech screening tool that can tip your physician off to some specific conditions. Fruity breath can suggest diabetes, while fish breath could mean big trouble for your kidneys. 

The world of medicine is now taking low-tech breath tests up a notch in the form of highly sensitive sensors that can help diagnose and monitor certain conditions. Soon, doctors will be able to read our “breath signature” and follow any changes that could indicate a red flag in the status of our health.
