Q:

I'm told there's a kind of wristwatch available that monitors sugar level in the blood. Can you help?

A:

What you are referring to is the GlucoWatch Biographer, which extracts fluids through the skin by sending out tiny electric currants. Glucose levels are measured using this fluid every 20 minutes for 12 hours--even during sleep. An alarm will sound if your glucose reaches "dangerous" levels. Fingersticks must still be used to ensure accurate readings. Low blood sugars do not register as easily; sweaty arms will also skew readings. When making insulin adjustments, it is important to confirm Watch readings with fingerstick monitoring. The GlucoWatch is available by prescription to detect trends and patterns in adults 18 and older.
