For millions of diabetics - measuring blood sugar levels is literally A PAIN!
While glucose meters are much improved - you still have to poke yourself everyday.
But, that's about to change.
Nearly 75 million diabetics and Americans with elevated blood sugar levels will be happy to know, a new glucometer in development is not only pain free - it does away with expensive supplies.
These new meters measure the concentration of glucose in interstitial fluid which sits between the skin's surface and underlying blood vessels.
They use light in the form of IR or infrared radiation, which passes through the skin. But don't worry. This form of radiation doesn't damage cells and tissues.
Measuring glucose this way is really pretty simple. If you shine radiation through human tissue, the light that comes through is used to calculate the glucose concentration.
It sounds simple enough, but there are a few problems. The radiation going through your tissue encounters other molecules which can blur the readings. To get around this, developers created complicated mathematical signal processing and amplification schemes to isolate and quantify the glucose.
There are other pain free technologies emerging. After more testing and FDA approval, these devices may be available in the next few years.
Without painful pokes, diabetics are more likely to test regularly and that means staying healthy, longer.
