Rumored feature for next Apple/Samsung watches could result in less pain for 25 million Americans

But even limiting this feature to monitoring blood glucose levels could result in heavy demand for Apple and Samsung’s new smartwatches equipped with the capability to produce painless blood glucose readings.In the U.S. alone, there are 25 million insulin dependent diabetics according to the World Health Organization (WHO); that number is rising thanks to the poor diet and lack of exercise that most Americans experience.

If Apple and Samsung do offer this feature on their new smartwatches, there is no room for error. A reading that is off by a even a small amount can result in the user taking too much or not enough insulin. With the latter, the diabetic’s blood sugar remains too high and could affect things like the user’s eyesight. If too much insulin is injected, a diabetic could suffer from  hypoglycemia (low blood sugar) and pass out.
