T2D news & developments – Week 26

Dog nose
This is an overdue post about last weeks developments. I got a news tip from t2d blogger Bob Fenton about a study [1][2] concerning exhaled breath, dogs, and low blood sugar. More specifically, it was a study on the chemical isoprene as a indicator of hypoglycemia.

The researchers believe that it is the levels of isoprene in human breath from which dogs detect hypos. It is not yet known why low blood sugar elevates isoprene levels. Since dogs can pick it up as a scent, and given that nanotech devices have already surpassed dog´s noses in picking up explosives molecules [3], future development of test technology that mimic the detection of that scent should be feasible.

The study links isoprene to low blood sugar, but when it comes to high blood sugar which is also known to be detectable to dogs, it stills seems to be a mystery whether it has to do with isoprene levels, other organic compounds in breath vapor, or a something entirely different.
