Bad breath as sign of disease? Liver disease, lung cancer may be detected by e-noses
from Scientific American via The Huffington Post
If the ancient Greek physician Hippocrates diagnosed you with fetor hepaticus (bad liver breath), it would not be an insult but a friendly warning. It meant the scent of your breath indicated you were going into liver failure. Much of ancient Greek medical knowledge has fallen into obscurity, but using the breath as an indicator of health remains. Researchers have for years worked to develop accurate, inexpensive and portable electronic olfactory sensing technology that can be used to detect and monitor asthma, kidney disease, high cholesterol and a number of other conditions.
