4 New High-Tech Tools to Help Control Diabetes

New Diabetes Control Tools: Continuous Glucose Monitors continued...

There is some debate about the accuracy of CGMs compared to regular blood glucose meters. "Scientists are creating standards to measure the new devices' accuracy," says Klonoff.

But some research already shows encouraging results. The journal Diabetes Care published a study of 91 diabetes patients. Subjects using CGMs spent 26 percent more time in normal glucose range than a control group without the devices.

Does this mean that people can toss out their dreaded lancets? Not yet, says Sabicer. Currently, all CGMs instruct users to do a "confirmatory" finger stick test before taking action, such as injecting insulin. Also, CGMs aren't approved for those under 18, and insurance may not cover the devices.

But Kowalski, who has used a CGM , says that many people -- including him -- are already beginning to free themselves from finger sticks. He's down to 2 finger sticks per day and he does this only to calibrate the device. The rest of the time, he relies on the CGM readings.

"It is life-changing," he says, adding that he believes continuous sensing will soon completely change diabetes.

"Certainly, we're moving toward a finger stick replacement with improving the accuracy of these devices," says Sabicer. But for now, Medtronic urges patients to keep double-checking readings.

Another advantage of continuous monitoring: It alerts a patient when glucose is too high or low. Although some users have complained of being awakened too much, an alarm will sound if glucose levels fall dangerously low during sleep. "It's a great tool that's never been available before," Sabicer says of CGMs. "Patients have a security blanket or insurance policy that's always looking out for them."

New Diabetes Control Tools: Combination Continuous Glucose Monitor and Insulin Pump

Patients who use insulin now have another option besides stand-alone CGMs. Medtronic's MiniMed Paradigm REAL-Time is the first combination CGM and insulin pump.

"Patients can both monitor their blood glucose and administer insulin therapy through the insulin pump."

It's not an automated system; patients must still make decisions about insulin dosing. But the Juvenile Diabetes Research Foundation hailed it as a "significant step" toward one of its major research priorities: That is development of an external, artificial pancreas that could someday automatically measure glucose and deliver insulin -- much like the real thing.

More recently, the FDA approved a new physician-use continuous glucose monitoring (CGM) system. Patients wear the CGMS iPro Recorder for three days, and physicians can review the data.

New Diabetes Control Tools: Diabetes Information Management Software

Increasingly sophisticated software programs allow patients who use regular blood glucose meters to track and analyze trends, Klonoff says. Patients can download stored data from their meters onto a computer through a USB port. Then, for example, they can view charts that show what percentage of time their glucose levels were within normal ranges, as well as above or below normal.

Your level is currently

If the level is below 70 and you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
