We Finally Know How Dogs Sniff Out Diabetes, University of Cambridge Study
For years, assistance dogs have been used to detect low blood sugar levels in their diabetic owners and warn of an impending hypoglycemia attack. Scientists have finally figured out how dogs are able to accomplish this feat—an insight that could lead to new medical sensors.
Dogs don’t so much see the world as they do smell it. Our canine companions can detect the tiniest odor concentrations—around one part per trillion. For us, that would be like detecting a teaspoon of sugar in two Olympic sized swimming pools. This allows them to work as medical detection dogs, where they sniff out various forms of cancer and diabetes.
