Even as the number of people suffering from heart disease, stroke, and cancer declines the number of people diagnosed with diabetes is steadily climbing each year, this means that for more and more people a truly noninvasive glucose monitor would be a godsend.
The fact is that the key to managing diabetes and heading off the worst of the detrimental health care effects associated with the disease is to keep glucose levels under control as much as possible.
In order to do this glucose levels need to be checked multiple times each day and each time a check is perfomed a blood sample must be taken, usually by pricking the finger. This equals a lot of blood and a lot of discomfort for a growing number of people. A reliable noninvasive glucose monitor would change all that, as a noninvasive glucose monitor is, by definition, bloodless and painless.
Unfortunately, a true noninvasive glucose monitor that is FDA approved and able to replace the blood sample type glucose meters is, as yet, unavailable. There are noninvasive glucose monitors, like the glucowatch, which are worn on the wrist like a watch. These noninvasive glucose monitorsread the glucose in a small sample of interstitial fluid that the machine draws from the sweat glands by means of a small and painless electric charge. While the current technology in noninvasive glucose monitors cannot replace the blood sample meters, it is able to take a reading every 20 minutes for up to 12 hours at a time, recording up to 250 entries with time and date stamp. This makes the current noninvasive glucose monitor invaluable as a tool to track and trend glucose levels for proper diabetes maintenance. Most of these noninvasive monitors can also be set to alert the patient automatically if the blood glucose level reads outside of the preset limits.
The current technology in noninvasive glucose monitors cannot replace the modern blood sample glucometer, but technology is advancing every day and a completely reliable noninvasive glucose monitor will soon be able to replace the constant finger sticks that most diabetics must endure.
