Continuous glucose monitoring systems (CGMS) may not make life with diabetes any easier. But they can definitely improve health, if you can deal with the hassle and expense. So how do you know if such a system is right for you?

As many readers already know, CGMS give a nearly continuous readout of glucose levels in tissue fluid, the wet stuff that oozes out when you have a scrape or a burn. To read these levels, you insert a long-lasting sensor under your skin, a process that feels similar to a needle stick. The sensor is made of material like the filters used in dialysis. It measures glucose levels and radios the results, via a connected transmitting device, to a small receiving device about the size of a pager.

This sounds nice — much more information without all the needle sticks. Unfortunately, you still have to do fingertip blood checks 2–4 times a day to keep the monitor calibrated. And the information you get from the meter is only valuable if you know how to use it.

Originally, CGMS was for your doctor. You got a continuous 72-hour readout of blood sugar levels, with a nice graph to go with it. If you conscientiously wrote down what you ate, your exercise, and medicines, your doctor would learn a lot about your body’s use of food and insulin. The doc could adjust insulin dosages and other aspects of your care. Then you gave the monitor back.

Studies showed this treatment reduced A1C levels by 0.4% to 1.0% or so. Many people with diabetes wanted this capability for themselves, so they could regularly adjust their own treatment and self-management. Now thousands of people use CGMS continuously. But how well do they work?

Advantages
According to manufacturers’ data, “You can easily and discreetlyview your current glucose values continuously throughout the day,” without having to do a finger stick. It’s easy and discreet. The monitors have “trend arrows” that show you if your level is rising or falling quickly, so you can prevent highs and lows.

Most CGMS have alarm systems that tell you when you are getting close to a preset high or low limit. This hypoglycemia prevention alarm enables insulin users to keep much tighter control, as they don’t have to fear going low as much. An ICU physician named Kristin commented on a Diabetes Self-Management blog entry that she could now work a busy ICU shift without fearing lows, because of the CGMS.

According to this WebMD article, continuous glucose monitoring can help “identify fluctuations and trends that would otherwise go unnoticed with standard HbA1c tests and intermittent fingerstick measurements.”

“For example, the device can capture dangerously low overnight blood sugar levels which often go undetected, reveal high blood sugar levels between meals, show early morning spikes in blood sugar, evaluate how diet and exercise affect blood sugars, and provide up to a 72-hour complete review of the effects of changes made to your therapy by your health-care team.”

If you are a dedicated investigator, you can use CGMS to understand what’s happening with your blood sugar levels. Diabetes Self-Management reader Jim Snell used it to identify that his sugars were shooting around wildly because of his liver dumping glucose into his blood. Watching the CGMS, he learned what provoked these “dumps” and when they happened. The CGMS info enabled him to drastically change his medications, and his A1C has come down dramatically.

Using a CGMS, Diabetes Self-Management blogger Jan Chait discovered that her insulin was working on her much faster than she thought, so she was able to change the timing of her insulin to match her intake better. She says her CGMS has also helped her prevent hypos.

So What’s the Downside?
With any medical equipment, problems are possible. Although studies find that the sensor readings usually are close to fingerstick numbers, there can be significant differences (up to 15%). It takes glucose around 5–10 minutes to move from blood into tissue fluid, or back, so the CGMS measures lag behind what’s really happening in your blood if things are changing rapidly.

The CGMS doesn’t replace fingersticks. As I noted above, you still have to check your blood glucose level 2 to 4 times a day to keep the CGMS calibrated. Calibration is an ongoing job with CGMS. They also say you should not make “treatment decisions” (like taking extra insulin) based on a CGMS reading without taking a conventional blood glucose reading first.

The sensors are only good for about 3–7 days, since they are made of really thin stuff. They’re not that hard to insert, but they are expensive — $35 to $100 apiece. Some users, however, leave the sensors in a few days past their expiration time to save trouble and money, and they say they work fine.

New kinds of sensors are being developed that are sturdier and can stay in place for about 140 days, but we don’t know when they will be available on the market.

The monitors themselves cost from about $1000 to $1400. Some you can buy online with a prescription. CGMS need a transmitter battery so the sensors can communicate with the monitor. Depending on the model, these may need to be changed once a year or so and can cost around $500. DiabetesNet.com provides a breakdown on available products and their costs at this Web page.

Although insurance will often pay for the CGMS, and sometimes for the sensors, some people find the costs and hassles too much. Diabetes Self-Management blogger Eric Lagergren thought the information he was getting wasn’t valuable enough to justify carrying around another attached box (along with his pump.) Other users complained of too many calibration errors.

I think anyone with any type of diabetes could benefit from using a CGMS for at least a week, if he were willing to record what he eats and does, and his medicines, and try to make sense out of it. Hopefully, he would have a doctor who was willing to work with him.

To get up to speed on noticing your own patterns and making adjustments, one week will probably not be enough. You would probably need a month or more. Some people use them for years as a safety net and guide. But if your A1Cs are good, and you don’t have a problem with hypos, you probably don’t need one.

Of course, most people probably won’t spend $1000+ on a CGMS just to use for a week. The best thing would be if people could borrow them, as from a library, or rent them for 1–4 weeks, and just buy the sensors. Some places do rent regular meters, but I’m not sure about the CGMS. If you know of anyplace like this, please let us know.

  1. I have been using a CGMS now for about 18 months and would not trade it for anything. Yes, it is important to calibrate the unit several times a day, but it sure is nice when playing golf to be able, at an instant, to see my current glucose level and stay out of trouble. I am not going to pretend there have not been days when the CGMS was off from my current blood glucose, but I just re-calibrate the unit and within a few hours I am getting the readings I expect.

    Do I like it? Yes! My A1C has dropped more than 15% since using the device and the nice thing is the CGMS is allowing me to more tightly control my glucose levels with the predictive alert. Many times the predictive alert has prevented the actual “set” alarm from going off, because I can take corrective action beforehand.

    It is expensive, but I look at it like this: By being able to maintain closer control of my diabetes, I am helping to protect myself from some of the long term complications associated with diabetes. That’s real preventative medicine, and it sure beats the alternative. By-the-way, this year I will celebrate my 49th year as a diabetic.

  2. My wife has the medtronic pump and sensor system. About 50% of the time the sensor reading and the finger stick reading are within 15%. The other half the time the sensor is up to 50% off. If you glucose rate is 120 to 150 the sensor is fairly accurate. As the rate goes up or down from that rate the error increases significantly. Often the sensor will read 100 and the finger stick will be in the 50’s or 60’s. The same with reading above 250. The sensor system when it is working takes a lot of pressure off the person. When it is off, you are constantly taking a finger stick up to 15 times in a day. The sensor system and pump are great assets to the user, BUT Medtronic has some major engineering and quality control problems that must be addressed. The alert volume is to low, the sensor quality control needs to be better. When it works it is a great system.

  3. I have been using a CGMS for almost 2 years and really like it. As of this morning my A1C was 6.5, down from 7+. While it is frustrating to have it alarm during the night, I love not having to worry about those 3 AM lows. In addition, I can care for my granddaughters (5 and 2 1/2) and be aware of what my glucose levels are. The girls
    know that the sound of either the vibration or the audible alarm mean I need to stop whatever we are doing to care for my needs. It is teaching them about my diabetes without frightening them with the “stuff.”

    I also really like being able to determine what foods may be causing spikes or activities may be causing drops.

    In short, it has been the best thing I’ve found except the pump in my 52 year history as a diabetic!

  4. Thanks for your report, David. I’ve been interested in getting a CGM for a while, but since Medicare does’t cover them, the cost is too onerous on a fixed income. My hope is the cost will come down and the accuracy will go up.

  5. I’ve been interested in a CGM for a while, but I need more information on the ‘cons of having one, much more information than that it still requires the same number of fingersticks I already do per day as a Type 2. For instance, does the sensor use afhesive on the skin to stay in place? As someone with a pretty extreme contact allergy to adhesive, this is an issue for me. My favorite forms of exercise all take place in the water; could I still do them? How much does the sensor probe move around in the body, and does it cause any pain if it does move? How useful is it if you only take oral medications and not insulin? I’d love to see an article addressing more of the everyday lifestyle pros and cons, not just one about monitoring, calibration, and fingersticks.

  6. I wore a Medtronic CGM for two months and hated it. Besides the fact it was just another device to attach to my body I found that during intense exercise, aerobic and weight lifting, the CGM would loosen up and come off. In order to wear the CGM I had to tape it to my body which caused more skin irritations. I finally decided to give up wearing this device after I developed an absess at the insertion site. I’m always looking for anything that will help me on my quest for tight control. For now I’ll keep pumping and checking my BG levels 8-10 times a day. I do know people who wear a CGM and they love it. I guess its a personal decision.

  7. David:

    Thanks for another excellent article.

    Currently the cost versus technology payoff is not as good as one wished. I suggest that we are a bit early in the performance curve with not all the bugs wrung out or optimizations done.

    It has not yet got to the $ 20 caveman meter cost and availability although it raises a curious question as to why one needs to use the $20 Caveman meter to keep the $1000 CGMS plus $ 80 sensor in line so that cost of operation includes the CGMS sensor plus caveman machine and roughly 5 to 10 strips a day.

    Just as excellent comments of other readers, I now rely on mine to keep me on the straight and narrow and would miss if it went away.

    Cost and insurance are a nasty pain in the derrier.

  8. I have been using the Dexcom 7 plus for over 2 years now and wouldn’t trade it for anything. I have been type 1 diabetic for 30 yeaars and keep my A1C around 6 and haven’t had above 7 for probably 8 years now. The problem is I have become hypoglycemic unaware and had severe problems with lows! Since I got my cgm I have only had 1 instance of a low where I required assistance and it was due to an illness.

  9. I have been a Medtronic pump user for 9 years and a CGM user for 6 months. There are definitely pros and cons to the system but as long as it works correctly I like it. Yes, there are cost issues, but Medtronic allows you to make payments interest free for two years.
    There are definitely sensor issues that need to be resolved to make the GCM work better. One of these issues would be the adhesive on the sensor. This summer was very hot and if you’re like me and tend to sweat a lot, forget about wearing the sensor cause it won’t stay on for more than an hour. The adhesive is on the outside of the sensor itself, and you click the transmitter onto it. There is no adhesive on the transmitter so if you don’t want that to feel like it’s flopping around, and it will feel like that at times, then you need to tape the whole setup down to your skin. The best thing to use is a square of IV adhesive covering the whole thing but there’s another high expense. I now use a couple bandaids crossed over each other to hold the transmitter in place.
    As for feeling the sensor after it’s been inserted, it does happen occasionally if I move a certain way, but not very often.
    For the most part, the readings are accurate within 15%, and usually if it does read a little off, it reads higher than a fingerstick does.
    To make a long story short, my biggest problem with CGM would be that the adhesive isn’t strong enough in certain conditions for a full three days wear. There needs to be some way to add adhesive to the underside of the transmitter to minimize the flopping, which can ultimately pull the sensor out. All this is based on Medtronic’s system so I don’t know how other companies’ products work, but I hope this helps people who are questioning whether or not to control their diabetes this way.

  10. I started using a CGM about 3 months ago. The additional information was very valuable. I found trends that never showed up with testing before meals. (Need more insulin after breakfast than normal). I also had several times when the sensor would go off in the night indicating I was hight or low and it was wrong. This is very frustrating. I too have had times where it is very close to my meter reading and other times where it is a 100 points higher or 30 points lower.

    For the trends it is great but accuracy to be improved.

  11. CDE and Pump Trainer, Gary Scheiner, of Integrated Diabetes Services in Philly rents CGMs to patients for a one to two week trial, and he works with patients remote as well.

    I tried the CGM through Gary and found it didn’t help me enough to make it worthwhile. I posted the story on my blog on DiabetesStories.com, but here it is:

    WE’RE DONE, WE’VE SPLIT, DON’T CALL ME - AT LEAST NOT ‘TIL YOU’RE OLDER

    My Dexcom 7 CGM and I have had nine days and nights together and we’ve parted ways. And, as if it knew I was not happy with it, it gave me one last kick in the teeth coughing up its last numbers.

    I met a friend today for brunch in Manhattan. I walked from my apartment in Brooklyn over the Brooklyn bridge and then took a subway to the cute little Italian bistro where we were meeting. The walk took about 90 minutes.

    After being seated and looking at the restaurant menu I took out my meter and tested. I was “80.” I took the CGM receiver out of my pocket. I was “80.” Unbelievable! This is the first time since CDE/Pump Trainer, Gary Scheiner, slapped the sensor pod on me last week in Philadelphia - and I carried it across state lines - that both showed the same number.

    I know the CGM’s numbers are not expected to match up precisely with your meter numbers. I know the CGM tests interstitial fluid and not blood glucose and there’s a difference. I know there’s a lag time on the CGM of 15-20 minutes. I know you’re not supposed to make dosing decisions off the CGM. I know that meter readings vary up to 20%. I’ve also learned that means if you test on your meter and get 80 and you test immediately again, you might get 80 or you might get 68 or 92 or 104. I know all this, yet after its first week of so many misses, the CGM immediately won back my trust, and my hope, with that “80.”

    Two hours later after a fairly low carb lunch my friend and I were strolling around and the CGM read “180.” Hmm…I thought, well I did have a few roasted potato pieces and a half a plain cookie the waiter brought along with the bill, maybe I need another half unit, so I took it. Then my friend and I spied a new concept yogurt store where you make your own frozen yogurt and toppings so of course we had to go in and see. And we had to put that tiny paper sample cup under the raspberry and peanut butter yogurt.

    Now walking back to my friend’s car I reached into my pocket to see what number was on the CGM. It said “222.” Hmmm…well I had just had what was probably a quarter cup of frozen yogurt, guess I need another 1/2 unit, which I took.

    Sitting on the subway platform 15 minutes later waiting for my train home a thought came barreling through my head…hmmm…”222″ … I’m hardly ever over 200. Let’s see what my meter says. My meter said, “108.” My meter also said, “What the hell are you doing dosing off your CGM!!! You know better than that!!!” Surely I do, but I had forgotten in the romantic glow of that “80″ when the CGM won my heart back at lunch. I so wanted to be in love with my CGM just like the many people I’ve talked to are with theirs.

    I pulled the CGM display out of my pocket and went to enter the “108″ to calibrate it and it gave me an error reading. It actually said, “ERR” which is just how I felt, especially if you add a few exclamation marks, “ERR!!!.” When I got home a half hour later, I looked through the booklet and saw my sensor was done, and it had had the last laugh all the way to its untimely end.

    A CGM? Not for me. Not until its accuracy is twice what it was for me. About 50% of the time it was tracking 10 - 20 points apart from my meter, the rest of the time it was anywhere from 20+ to 75 points away. It alarmed me telling me I was “53″ when my meter said “85″ and it fooled me into trusting it so many times.

    I wanted to love you CGM, truly I did. But I’m going to wait til another generation or two comes along. Until a CGM is really ready to love me back. For now I’m sticking to finger sticks, and running for the juice!

  12. EXcellent comments from Riva:

    Short term rental presents a problem with such a device. It took me a couple of months to finally understand how the machine was working and what the differences in readings mean with the $20 caveman finger stick machine.

    Now after months of use I now understand how to read/interpret the cgms readings.

    The reason for this is:

    a) as long as blood glucose is slow and relatively unchanging, yes, the interstitial sensor readings are pretty good at tracking the caveman machine.

    b) the delays at the interstitial level mean that on any sea change and the faster it occurs , there will be a metering delay and interstitial delay until the the CGMS tracks the caveman $ 20 fingerstik machine. When the readings are close, one knows that the BG is running quiet and stable. When there is a big difference in readings, that is indicating sea change. This should not be interpreted as “error”s in readings notwithstanding the heart stopping inital human brain response. I had an even worse “what the hell” is wrong here and what crap is this.

    c) now I have been exercised thru this mess and the idiosynchronies of the CGMS over a longer period; it can take up to a month or possibley more to become more accclimated. Unfortunately, if one quickly uses and graphs repeated finger stick readings versus the CGMS, the $ 20 caveman machine will catch the accurate fast transitions while the CGMS gives a delayed and averaged reading thru the interstitial tissue/cgms filtering delays over the period of change.

    Here again my inital sentiments is that this crap does not work. Later, watching the trend data over time provided invaluable data and also when things change. The key is to use the CGMS to actively wtach the trends and then at key shifts, use the $ 20 caveman machine to accurately check what is going on. It is alos wise and important to watch the cgms readings and if they seem unchanging for long periods of time; to grab the caveman machine and do a QC check and see if we have truth. There are reasons for stalls and problems that leave the Receiver stuck reporting old data without advising user of any interference problem causing the hiccup.

    This is why prior to inserting insulin dose, it is critical for a cgms user to do a $ 20 caveman finger stick resdings to ensure what actual numbers now are and the select appropriate dose. I have saved my butt many times.

    Yes, in the end after working with the cgms, its data and continuous monitoring are critical, helpful and extremely beneficial.

    I can see how a weekly rental would be extremely beneficial to someone just needing to run periodic spot checks and check body operation.

    Knowing what I know, I would strongly advise for a first time user to use it for a month till settled in and finally got usefull data. If after getting good data and body BG operation is stable like predictable slow waves on a placid lake and no nasty liver dump and/or overdumping dawn effect activity, then one could swap to a weekly rental for periodic checks evefry so often.

    I wish folks like Dexcom would share more up front guidance and sharing issues of operation to help a starting user but due to Regulatory crap and lawyers - theirs and the FDA end up shipping a vague user manual nor decent guidance for first time users.

    As an electronics engineer using all sorts of high performance accurate test gear, I really struggled at first and my response was - “Get the Gun Now”. What I got was NOT what I expected - honest differences and issues aside. That resolved; it is still insulting to need a $ 20 caveman machine to keep oneself or CGMS on correct tract given the CGMS is $1000 plus sensor cost est $ 50 to 75 based on actual number of days use - 7 to 12 days.

  13. I post this story and question not to scare anyone but to learn if anyone else has had this issue. I used the Medtronic CGMS and, as many others do and as I had been doing for months prior, I left the sensor in for longer than 10 days. When I removed the sensor’s adhesive and exterior component, the sensor’s thin wire remained under my skin. I initially saw its tip protruding from my skin, but it quickly disappeared. Long story short, so far my doctor cannot find it by poking around, and an x-ray doesn’t help because the material does not show up. Has anyone had this experience, and if so, any suggestions on what to do?

    Posted by Marty G |
  14. check the CGMS group and the dexcom group on tudiabetes.com and I believe there are some folks have run into.

    I always pull my old sensor off very slowly and carfeull not tto bend sensor wire and so far have been lucky doing this after 10 months using cgms and getting 7 to 12 days per sensor on a dexcom.

    Hope this helps.

  15. This is my second post, but I had to respond to Nancy’s comment. Initially, I used the Medtronic sensor in hopes that it would be easier to work with just one piece of equipment to carry around. I still have scars from what the cover tape did to my skin in spite of trying everything Medtronic suggested. The whole thing came off whenever it was hot and that was frustrating and expensive! In addition, it was not very accurate. I am much more comfortable with Dexcom 7. It did not have any come off over the past summer and is more accurate, while I still test, especially before doing a correction bolus, I find it is close to target more often than not. All in all, it is better carrying both the pump and the sensor and having it record accurately and not fall off! It may not be for everyone, but I love it and can hardly wait for the next generation to come out!

  16. I initially thought cgm was the greatest thing on the planet for someone like myself with type 1, but I have stopped using it for many reasons.
    I have found that “micromanaging” my illness causes the disease to comletely control me, rather than me control it. My body is to glucose as a wood burning stove is to heat, the fine tuning is gone (no glycogen in my liver at all.) I have found that taking a broader approach to control is better in the long run than the extreme hassles of using the cgm. Not to mention what other respondents have noted, that when your levels are above 250 or below 100 the thing becomes severely inaccurate, almost retarded.

  17. I am really interested in getting a CGM, especially for running. I am a distance runner, and would really like to stay on top of my sugars while out on the trails. But it sounds like they don’t stick when sweating or working out. I wonder if there are any other runners who have used a CGM who could let me know if it is worth getting one. I have a Medtronic Paradigm pump(522).

    Posted by Tom Halverson |
  18. I did not like the Medtronic CGM. The hassles (falling out, tape not adhering, painful and bloody insertion requiring more than one needle/insertion(costly), multiple caliberations in addition to multiple fingersticks; airport security; having to turn it off when i fly…)

    If you are feeling badly because the costs are preventing you from being able to make this purchase- dont. I suggest testing as often as you can. The CGM requires you to test often. So really, in my opinion, all you get is a trend of blood glucose, sans the accurate blood sugar reading. You can make a chart on your own- no need to spend thousands for a chart. Please please dont feel badly if you cannot afford this device. You are NOT at a disadvantage, in my opinion. Test often. Test as much as you can…you can figure the trends without the costs and pain of this device and its accessories. Trust me on this one!!

  19. It has changed my life.
    i have been type 1 for 42 years. I have managed to hold down extremely difficult jobs including a CEO post for 10 years,racing motorcycles, driving very fast vehicles….all achieved by checking blood sugars literally hourly every day. Even though I had warning symptoms of lowering blood sugar levels. I simply believed that paradoxically tight control gave me more freedom…..it did.
    I went onto a Medtronic pump in May 2012 …provided by the NHS…love it…and while being trained to use it learned about the Medtronic CGM system. I was going to buy a new Audi TT convertible but decided to stay with my MX5 and invest in the CGM system.
    It has been literally life changing. In 10 months have not had any night time lows and woken up sweating, no point when close friends ask me if I am ok, no problems while grafting on the allotment which had previously been a need for half hourly blood sugar tests.
    The results are not absolutely accurate..but very close and I get very early warnings of highs or lows…if it warns that I am going low or high I still do blood test, and before driving I still do blood test….I take it very seriously. However quality of life is dramatically improved, control now so relaxed compared with previous regime, 2 good holidays abroad without any snags whatsoever. I have been a motorcycle addict since childhood but virtually stopped riding because wind and weather could mask symptoms of low blood sugars developing. My experience of the CGM system is such that I can again ride motorcycles with ampe warning of lowering blood sugars, and have treated myself to a new Triumph Tiger 1050 in consequence.
    Medtronic as a company is simply outstanding to deal with, and their specialist with whom I deal….John Pemberton….is simply amazing….email or phone answers always by return…he has such a good grasp of the system.
    Feeding into the Medtronic Carelink system dead easy and so informative. Recently I achieved 93 per cent readings over a week within my preferred blood sugar levels of 4.5 to 10 percent. Because I am not eating to avoid lows lows I have also managed to loose 7 lbs in weight.
    No problems with adhesion, showers no problem…..it has been simply brilliant. It has changed my life whereas Audi TTs soon become boring!!! Very highly recommended.

  20. I am in the “thinking mode” about getting a Pump, presently saving my money so I can possibly get one. I have read a lot of information about one and like the technology that comes with it, but I am not sure I am ready to go through another “learning process”. Any ideas?

    Posted by Darlene |
  21. I have been on the Medtronics insulin pump with CGM for 2 months. I am on my 9th sensor. Out of 9 sensors only 1 has proven to follow test strips for the six day period. Typically results start to vary within 2-3 days of CGM insertion.

    I am not very demanding so I am willing to accept variations between the CGM and glucose reading………BUT……….I have had MULTIPLE times where there is greater than 200 points difference! These variations can last for hours.

    The pump itself has been excellent but the CGM is TOTALLY unreliable. I know that the CGM is only an indication of glucose trends but a CGM reading of 60 with a blood glucose of greater than 300 makes the CGM useless.

    When the sensors deviates I have no indication of issue. The unit I am using provides alarms and threshold suspends. I have turned both off due to the HUGH variations.

    I have been in contact with Medtronics MANY times. This includes hours of phone conversations and many, many emails. All recommendations have been followed but the misleading CGM data continues.

    At this point I plan to discontinue the CGM and use the pump.

    I really like the CGM when it works……….but I have found that without burning a lot of test strips I have no confidence in the CGM.

  22. I use the Metronics new pump and sensor. I find it to be between 20-50 points different from my blood gluclose. I don ‘t adjust my insulin based on the CGS. I do find it useful to predict highs or lows. My insurance used to pay for the sensors but it does not pay anymore and refers to it as experimental. I have read many post stating that it is not worth using. I must state that anything that can help prevent trips to the hospital or other damages caused by poor control of this chronic dease show be recognized as a help and be covered by insurances. In the long run it is more cost affective than hospital runs or other things that can occur. I have been a diabetic for 47 years and I find this a better way to come close to be normal.REMEMBER THIS DOES NOT REPLACE A HEALTHLY PANCREAS.AND INSULIN. IS. NOT A CURE. THE CGS IS A WAY TO HELP COMPLIMENT. THE DELIVERY SYSTEMS. WHICH YOU SELECT TO USE.
