      When you change your insulin pump site, do you tend to notice a spike in your blood glucose levels afterward?
      I oftentimes give myself a little insulin for when I go unplugged while changing pods, depending on what my current sensor reading is.

      Always, until I began to increase the "cannula fill" amount. I found I need a good bit more than the (1.3u) to "prime the site" to have the next blood sugars be in goal. Just remember "every body is different". Darn than OmniPod does not let you change that amount, have to use "fake carbs". Something to consider.....

      "Slightly," I think, maybe. Insurance companies change their policies, constantly. Prescription coverage changes every time I look at it. Medicare is a huge question mark. Honestly, Health insurance has become a big money making business, for them. I get different answers every time I call, depending upon whom I am talking with. I say it's time for socialized medicine.

      Sometimes, which makes sense to me. It seems like it takes a while til the new insulin is absorbed.

      If you use a continuous glucose monitor (CGM), where do you prefer to view your CGM readings?
      I find a using the T-Connect app I have the main features needed, CMG, bolus, battery level and remaining insulin.

      Mostly pump because I want to quickly see insulin on board. Tandem on IPhone when holding my great-niece while she sleeps since getting my pump out of my pocket always wakes her ☺️. Dexcom app if not in need of insulin.

      My pump (Tandem X2). Since I have to carry a work phone close to 247, I don't want to deal with two phones (device overload!). As I go about my day, looking at my pump meets my needs, I can decide to bolus etc - and edit the bolus. For more in depth data review and analysis, I use the TConnect.

      How much of this is intentionally misleading? My mail order prescription service says that can’t possibly know the cost of a medication until after it’s been shipped, which is too late to cancel or return, of course, and makes it impossible to comparison shop.

      I don’t remember what happened to my A1c in the first 6 months, but it probably went up as I was having frequent low blood sugars (45 low glucose events in 30 days) when I first started wearing my CGM.

      A1c did not change. Standard deviation dropped from 90 to 45. All this in 2006 with the Minimed Harpoon, aptly named for the size of the insertion needle.

      I feel that something that compromises the CGM’s blood glucose reading accuracy is the insertion step. Not sure if its the design or what, but in my experience I have lost many sensor tapes (guardian sensor 3/medtronic) because of puncturing capillaries. And at times I have to calibrate up to 4-5 times a day, which makes you think if the sensor is actually doing its job.

      My A1C did not change; it has been below 7 since I was correctly diagnosed and given insulin. The biggest change was that my husband was able to sleep at night.

      When I was made to get my first CGM, in July 2007, I wasn’t given a chose on which one I wanted, it was just Medtronic’s. It was a pain and inaccurate, so much that I stopped wearing it because of all the issues with it.

        Hey, Bonatay, you can get into normal range with a CGM. Exercise, go to low carb diet. IF I CAN DO IT, YOU CAN DO IT. Eat veggies like spinach and Brussels sprouts at every meal. Eat nuts and seeds every meal. Include non-sugared peanut butter, almond butter. Get protein from sardines and wild-caught canned or smoked salmon. Add avocados and olive oil to your diet. Eggs, cheese, unsweetened yoghurt or kefir are good for you. Two ounces sweet potatoes, “yams” or canned pumpkin taste good, add fiber. Two tablespoons flax meal per day. I Tb wheat germ & 1 Tb yeast at breakfast and again at dinner. Don’t forget 4 Tb tomato sauce every day. For polyphenols have at least 1 cup Green Tea (decaf available). Save your kidneys by carrying a water bottle in your backpack. Yeah, it’s hard to kick carb addiction.

      I don’t recall my A1c’s changing when I first started on a CGM system. I usually ran between 5.5 and 6.0. However, since I’ve been on the Control IQ system with Dexcom G6 and Tandem, may A1c has consistently run at 6.1

      In 2009 I started on the Dexcom System 7+ and don’t remember much change in A1c but it did bring down the anxiety over Hypo events. Now the G6 with Tandem CIQ I have eliminated almost All Hypos

      My A1c did not change so much but I am guessing that my time in range and standard deviation changed a lot. I had many lows and and highs but my A1c overall was good. Now I have less lows and highs maintaining much more even management of my diabetes. CGM is a glorious addition to my life. I could not live without it.

      Going on GGM helped me drop from 7.8 to 7.1. Going on modified close loop with the 770G I have been able to drop A1C further to 6.9.

      I check more often, so fewer lows and highs, learning the trends and not being as concerned about lows, especially at night have been great. Libre 2 is a work of art.

      I tried the Medtronic version of CGM and it was terrible, ended abandoning it after 2 years(A1c went from 7.6>9>8.7>8.8) when I was able to get insurance that covered Dexcom then Tandem. Constant false alerts with Medtronic with no improvement in A1c. Pre Dexcom CGM, I was struggling with high A1c and trying for tighter control. Ended up having lows that I could t see coming and A1c went up. Post Dexcom CGM, the accuracy and seeing trends that I could trust allowed me to get my A1c went down dramatically from 8.8 to 6.5 in the first few months.

      I don’t think my A1c changed too much because pre-CGM I had so many lows that I wasn’t aware of. I started using Medtronic’s Sof-Sensors when they first integrated with the pump (2007 or 2008) and I can’t remember my numbers from that far back. It definitely helped me to avoid some of the most serious lows and highs.

      My A1c didn’t change in the first 6 months of using the Dexcom G5. The changes came later using the G6 because my endo insisted that I needed to raise my A1c to 6.5 – 7.0 from the 6.0 level it had been at for years.

      Using a CGM was never about “improving” my A1c. I’d fluctuated between 6.5 and 7.5 for years using finger sticks and MDI. Libre and Omnipod are, for me, about ease of use, not reducing A1c or increasing time in range. Those numbers have changed very little.

      My A1c really didn’t change but the highs and lows don’t happen as frequently nor are they as dramatic as before.

      My A1C improved because I’m able to be in the range of 120-95 more often without lows because I can see the low coming on the app. So I snack a little more often and skirt that nice lower “normal” range.

      I answered “NA” because I have been on a CGM less than 6 months, although the early trend seems to be decreasing A1C.

      My A1C before a CGM was a good 6.9 (the highest I ever had) and with the CGM it dropped to 6.5. While my BGs wildly swing in a wide range, they change quickly, so it balances out. Still not in control (TIR) and StDev that I would like, but maybe the best a brittle diabetic with a big appetite can hope for.
