Continuous Blood Glucose Monitoring in Diabetes

2 Mins read

One of the fundamental challenges in managing diabetes, especially insulin-dependent diabetes mellitus (or “juvenile onset” diabetes) is the lag between a sharp trend in blood glucose levels (up or down) and the diabetic’s awareness.  The sooner a diabetic can become aware of becoming hypo- or hyperglycemic, the sooner he/she can act to preempt this adverse affects, some of which (especially for hypoglycemia) can be dangerous.

One of the fundamental challenges in managing diabetes, especially insulin-dependent diabetes mellitus (or “juvenile onset” diabetes) is the lag between a sharp trend in blood glucose levels (up or down) and the diabetic’s awareness.  The sooner a diabetic can become aware of becoming hypo- or hyperglycemic, the sooner he/she can act to preempt this adverse affects, some of which (especially for hypoglycemia) can be dangerous.

Couple this with another fundamental challenge in diabetes — the need for painful, frequent blood glucose testing involving finger pricks for blood sampling — and it becomes clear why continuous blood glucose monitoring (cBGM), especially non-invasive, holds potential.  While the challenge of providing cBGM is currently more economic than technical, as a practical matter the solution has not yet emerged that is supported by industry.

Below (and based on an inquiry from a Quora member) is a 2010 listing (perhaps in need of  a recent update) of manufacturers developing continuous blood glucose monitors.

About author
I serve the interests of medical technology company decision-makers, venture-capitalists, and others with interests in medtech producing worldwide analyses of medical technology markets for my audience of mostly medical technology companies (but also rapidly growing audience of biotech, VC, and other healthcare decision-makers). I have a small staff and go to my industry insiders (or find new ones as needed) to produce detailed, reality-grounded analyses of current and potential markets and opportunities. I am principally interested in those core clinical applications served by medical devices, which are expanding to include biomaterials, drug-device hybrids and other non-device technologies either competing head-on with devices or being integrated with devices in product development. The effort and pain of making every analysis global in scope is rewarded by my audience's loyalty, since in the vast majority of cases they too have global scope in their businesses.Specialties: Business analysis through syndicated reports, and select custom engagements, on medical technology applications and markets in general/abdominal/thoracic surgery, interventional cardiology, cardiothoracic surgery, patient monitoring/management, wound management, cell therapy, tissue engineering, gene therapy, nanotechnology, and others.
