This has been so enlightening! I’m a thin, very active, and very healthy eating 60 year old with an A1c just barely in the pre diabetic range (5.7) per my last physical and lab results. I was shocked. So I bought this to see if I could find out when my sugars were high and after what foods. Well I was shocked again to find out how high my sugars went and how frequently I get big swings. I’m on my 4th day and have finally figured out through trial and error my diet and activity level and timing to give me a good Lingo score. I found that I need to eat less carbs (even though all were whole grain) and less fruit (I love fruit!) and only after some protein but mostly that I need to eat smaller meals and to stay active for about an hour after each meal to keep my sugar levels stable and from peaking so high. Yes it’s a little bit of a hassle but something I can do and so much better than medication or worse - having diabetic complications down the road. I would never have known without being able to have a constant monitoring system! It’s very easy to place the monitor and painless. And the app is easy to use. This will change my behavior and prevent so much pain and problems in my future. I cannot recommend this high enough if you’re pre diabetic or if you just want to have your eyes opened regarding what your sugars are on a real time basis. The best fifty bucks I’ve ever spent! It’s now 7 days later. The monitor stopped working on day 6. I called Amazon and they gave me a full refund without any problems. However, I still think the information was life changing for me. I would have liked more time to try different foods to see my body’s response, so I will try another one. I’m going to keep my rating at 5 stars because of how incredibly enlightening it was even though it only lasted the 6 days.

Heads up…Long review, I’m not a fan and can’t recommend it. I purchased 4 of these thinking I would get a good idea of what my diet and exercise was doing to my blood sugar for 2 solid months. First one worked okay. I did test it against a finger-stick monitor (Registered Dietitian here,) and found that it reads low. The monitor I used is made by Freestyle, same company (Abbott) that makes Lingo. My finger-sticks were about 5-15mg/dl higher than the readings coming from the biosensor. I tested it several times during the two weeks, most were 15mg/dl higher. I knew at that point that it wasn’t super accurate, but I could still see that even a tiny bit of sugary creamer in my coffee sent my blood sugar up and then crashing after a few hours if I didn’t eat anything else with it. That info helped me to give up the coffee creamer since I always tend to crash after sugar. I tested different sweet stuff, mixed with and without fats and protein. I was excited to continue with the next sensor and was planning to just stick consistently with my healthy low carb diet and not test sweets since I know I crash every time. I wore the first one without issue, knowing that it wasn’t super accurate I just looked for trends. It was fairly easy to take off after two weeks of wear, but I was surprised how sticky it still was. Hardly felt it on me or when I applied it or removed it. I could not sleep on my left arm or I would get odd swings in readings at night. After removal I waited two days and installed the 2nd. The second gave me a kinda high reading for me after an hour even though I hadn’t eaten anything yet, I think it was around 89mg/dl. Then I got the dreaded error: “Please wait 8 hours to see your reading or contact support.” No readings or history were showing. EIGHT hours? That seemed crazy. I did wait about 3, but nothing changed, so I emailed Abbott. I did get a response fairly quickly, maybe 12-18 hours. I’m sure a call would be quicker. I had to answer a billion questions and finally got an email back that a replacement was on its way. So I was told I could remove the sensor that I had on and trash it. Sensor 2 removal was tough. Since it was freshly placed, it was super sticky. After I finally got it off I was bleeding quite a bit, took a while to stop and yeah, that was fun. That one left a scary purple bruise. Since I still had 2 more sensors on hand I decided to place another on my right arm today (3 days later,) since my left arm is still bruised. I was a bit scared after the drama removal of the last one. Again, no pain applying. Whew. I was sure this would work. After one hour, (it takes an hour to calibrate,) this time it said my blood sugar was below 55. (Which BTW, I got that a lot when I wore the first sensor. When it’s below 55mg/dl, you don’t get a number, just <55.) then about another hour later I got the same error message again asking me to leave it on for 8 hours or contact customer service. Ugh. I did email Abbott a few hours ago and requested a refund for 3 sensors this time, no answer yet. I wore this one about 4 hours. Nothing. I just removed this second “error” biosensor and it was tough to remove like the last. New and very sticky, which is excellent if it’s going to stay on for 2 weeks, not 2 hours. Thankfully, I didn’t bleed much and no bruise so far. The app is pretty limited. Really needs improving. I did read that the Lingo goal is very confusing for a lot of people and I can see why it would be. It’s not intuitive. I got the hang of the app and was happy that it connects to Apple health and automatically adds my exercise. Easy enough to add food, but doesn’t connect to the Cronometer food tracking app that I use and love. I wish that the readings below 55 would be displayed since I tend to be hypoglycemic (low blood sugar) and it would be helpful to see what the lows were. I will say that I can typically feel my lows and my <55 readings did not feel like I was having a low. Wish I had confirmed a few of those with a finger stick. Great idea for self-help people like me. Needs lots of improvement. If you’re prediabetic or know an endocrinologist, or even talk to your family doctor about why you want to try one, especially if you’re worried about your health or have a family history of diabetes. I would ask for a prescription version of a CGM. Your doctor might give you one to try, but those need to be placed and removed by a health care professional. Your doctor will be more willing to give you a finger stick monitor if you’re willing to stick your finger first thing in the morning for a fasting reading, after meals and exercise. Monitor is cheap, test strips are pricy OTC. You can also get a prescription for test strips if your doctor sees a need. Seems scary, but it’s not too bad and it’s definitely more accurate if you're really worried about your health.

The lingo is great little piece of technology. It has a small profile and it works well. Here I address the major points: 1. Accuracy: I'm on my second lingo, and I compare its reading with TWO separate True Metrix glucose meters. Every time I have checked, the lingo reading is between the two reading from the True Metrix meters. So the lingo is never far off from what is the true value. The sensor does read low if you compress it, like when you sleep on it. But that is a minor issue. 2. Ease of application. The applicator is spring loaded and the unit goes on without a hitch. Don't be worried about what looks like a needle -- I feel nothing from the puncture when it inserts. I inspected the unit after removing it, and the probe looks like a flexible short piece of hair, so very thin and unobtrusive. 3. Sticking power: I bumped my first unit several times and it stayed on just fine. I prepared the area by shaving my hairy arm and cleaning it with isopropal alcohol. That seemed good enough. It finally came off prematurely after I got really sweaty and pulled of my shirt, which was sticking to my arm. I didn't feel it coming off an found that it had re-stuck to my skin a couple inches from where it had been. So I just washed my arm and applied a new lingo sensor. I purchased the little sticky pads that one can place over the sensor to protect it from accidental bumps, and that seems to work well, making it less likely to be pulled off. 4. The app: It works well and provides a running plot of the glucose data in 5 minute intervals, taking a running average over the data that is taken every minute. 5. Customer support: Support is great. They respond quickly and take care of the issue. My wife had a defective sensor and it was replaced right away. 6. Data: You can contact customer support to request your data, which they provide by email in CSV format. Two suggestions here: (1) It would be nice to be able to download the data electronically without the need to request it by email. (2) I would like to have the minute by minute data so that I can analyze the statistics. They tell me that they are working on electronic access but I have not heard back about getting the minute-by-minute data. Overall, this is a great little device that helps you see which foods and activities affect your blood glucose. And, it's nice having long term data to compare it with your A1c. In my case, it appears that the A1c results are much higher than reality.
