      Multiple daily injections users: Do you use a diabetes-specific app on a smart phone to track your insulin dosing? Share what works best for you in the comments!
      I use an InPen. Tracts my doses and gives report just like a pump. IOB total insulin etc.

      I’m looking for an app that reminds me of basal doses that keeps the time static as you change time zones. For example, I recently travelled to London. My normal basal dose is at 8 PM at home but currently 1 AM in the UK. The Apple Health app reminded me to take it at 8 PM London time instead of 1 AM. I really just want an app that reminds me at the same time my body is set at without making me think about it.

      In the past 12 months, have you experienced nausea and/or vomiting as a symptom of high blood glucose levels?
      Echo Mick Martin. Gastroparesis? Try ondonestron (sp?) one of the 10 best medicines ever invented. Also, "a forever learning curve" and "If in doubt, pull it out."

      For pump users: In the past 3 months, have you had issues with insulin delivery due to a bent cannula or occlusion?
      I hesitate to bring this up but I am quite sure this happens more than people realize. I use a tubed pump and small amounts of total daily insulin and have checked the tubing for YEARS for bubbles. YES, they are difficult to "notice" unless you have a good light behind the clear tubing because the insulin is also colorless. I detach and check the tubing in the morning and before bedtime if not before the evening meal...I'm talking about significant bubbles----8-10-or12 inches in length can appear and you would NOT notice them unless you were looking. I wonder how many people wonder why their blood sugar is occasionally high and it's being caused by a significant bubble...NO, not the champagne sized version that's often mentioned to "ignore." The pump company I deal with tried to get me to switch to injections instead but I am an EXPERT with the bubble situation. Also, comments over the years that I am probably not filling the reservoir correctly, etc....just plain silly. I am NOT new at this...LOL!!!

      I said yes to nausea, occurred with a bad pump site insertion and rising BG over the next 4 hours. I picked it up early w CGM notification and realizing that it was very unusual for me to have rising BG at that time of the day (morning) when on Control IQ pump. The severity was delayed because I had given a breakfast meal bolus via the prior site before the change, so BG was rising after 3 hours, and I knew something was not right. I think this is an important clue for pumpers- when I see people get in trouble w bad sites or insertion failures, the thought process usually is- I just put a new site in, it must be ok- or maybe it does not occur to people that the pump site could have failed--when it should be- did the insertion fail? ----If in doubt, pull it out!----- I pulled the site and could see the cannula was bent, so I know what happened and injected w a syringe, put a new site in, and was better in a 3-4 hours.

      I began playing Pickleball last year in March. When the temperatures started to rise the extra effort my body was experiencing because of the heat got my body hormones out of balance and I began experiencing nausea, higher heart rates and feeling very uncomfortable. I soon realized that I cannot play when is too hot or I’ll end up with ketones. Any new activity when on. Insulin requires adjustments. It’s a forever learning curve. Adding to the heat, last year I was having some absorption problems by the overuse of my abdomen. I have now move the infusion sites to my upper front side and it’s working much better.

      Have you developed lipohypertrophy due to repeated injections/infusions of insulin? Lipohypertrophy is a term to describe hardened lumps of body fat just under the skin that resulted from repeated insulin injections/infusion sites. If so, share how you’ve handled lipohypertrophy in the comments!
      After 62 years I have skin issues everywhere. I am an avid at rotating every time I change my infusion set. When I was on multiple daily injections, up to 9 per day, I had massive skin hardening. Since on the pump it’s not nearly as bad that’s been 33 years. I take very little insulin my daily basal comes out to 9 units over 24 hours I eat two meals that I count carbs for and try to keep at a minimum of 30-40 per day. Everything is going well. Rotation is key

      I use a pump and have had issues with insulin absorbtion. It seems I have a lot of them on the side I primarily use for infusion sets. I recently switched to the other side of my abdomen and dropped more than one point on my a1c.

      Does your T1D healthcare provider suggest new medications or devices that they think would be beneficial to your T1D management during your appointments?
      When I first started with my current Endo we would discuss the released and upcoming products and I would tell her about the 'off-market' applications and devices, we both learned from each other. But she was so good with helping me transition to the Dexcom and then the Tandem after Animas was pulled from the Market. She followed my Dex and even finer tuned my Basals and early this year I got an "unbeleivable" 5.4 A1c and we are both extremely happy!

      Yes. But then I self-selected when choosing an endocrinology clinic that pursues cutting-edge advances 40 years ago. Cutting-edge is a phrase that is also often called bleeding-edge because it is often experimental, hit or miss on results, and very expensive. I am convinced the “bleeding” refers to $$$.

      not anymore, and I am happy about it! Most of the time they were recommending things that had been recently pitched to them by a pharmaceutical salesperson or a durable medical supplier. The doctors would give patients the "free samples" and it was often not the best fit, then after the "free" supply ran out, the prices were exorbitant. Maybe it still happens, but I haven't seen it for a while.

      If you have never used an insulin pump with automated insulin delivery (also known as a hybrid closed-loop pump), what are some of the reasons you’re reluctant, or obstacles you’ve encountered? Please select all that apply.
      The need for better CGM accuracy is a big consideration for me. Also my control is pretty good right now (a1c in the low 6 range). Although I am tempted by the sleep and exercise modes which would be very helpful since I’m getting back in to exercise. So…I keep sitting on the fence…

      I don’t want to change from the Omnipod Dash to Omnipod 5 because the minimum target blood glucose is level is higher than where I like to keep it. My A1C is currently 5.0.

      For the last 5 years, the highest HbA1C I've had was 5.3. For the last 3 years the high, low, & average have been 5.2, 4.7, & 4.9. I'm not willing to go to an AID that sets a target of 6 to 7.

      I do MDI. For the last 7 years my A1C has averaged around 4.8. I have no reason to believe that a closed loop automated system could do that well.

      There are many reasons, as well as "something else." My arthritic fingers do not serve me well with a cell phone. I have trouble putting the needle covers back on to my insulin pen needles. If I had to take care of all the fine muscle issues associated with setting a pump up, I would probably require assistance. I am also not drawn to the issues I hear about tissue damage at the infusion sites, or knowing whether everything is seated properly and the insulin is actually flowing. Finally, I just have some kind of negative karma with electronics. I have worked as a lab biochemist. Somehow, I find the weaknesses of every machine in the lab. (the ideal industrial beta-tester) Having said that, what I hear about the numbers achieved with the tandem CIQ gives me pause to consider.

      Like others, the "closed loop" runs me too high - even the target bg is too high for me. I use the TandemX2 with BIQ integrated wqith my Dexcom G6. I also appreciate - and use - the temp basal function often. I would lose that with CIQ. L:ike Nilla Eckstrom (I think?) I like to be between 80-90, with maybe up to 120 after I eat.

    Have you (or your loved one with T1D) gotten a flu shot this year?

    Next

    Based on your responses from yesterday's question (what you usually do before exercise), what would you say is your ideal blood glucose range before engaging in 30 minutes of moderate-intensity aerobic exercise (i.e., working hard enough to raise your heart rate and break a sweat but still be able to talk)?

      It is a little useful if I look at the deviation on my blood sugar range. However, it is very useful if I have a good time-in-range but have not looked at how variable my sugars are

      I put “a little useful.” A1c is a helpful benchmark, but doesn’t really inform specific insulin dose adjustments like my pump/CGM reports do. I was happy to recently get my A1c down to 6.8% with fewer lows after years in the mid 7% range. This is about a year after switching to Tandem/Dexcom with Control IQ.

      A little useful – mostly because doctors seem to view it as the holy grail, at least in my experience. However, I feel that CGM data (time in range, standard deviation, and average glucose) make A1C an obsolete measurement. If you’re using a CGM, A1C isn’t going to tell you anything you don’t already know.

      I answered “a little useful” as HbA1c is a helpful benchmark, but TIR (Time in Range) is MUCH more informative in my humble opinion. (HbA1c does tell you when your blood glucose levels were high or low, only an ‘average’ of what they’ve been over the previous 3 months.)

      I put “other” because I am not sure how accurate it is? I find that my A1c varies greatly from my Dexcom 30, 60, and 90 day averages. For example, my A1c will be 5.4 while by Dexcom averages indicate the A1c should be more like 6.1. Not sure why there is such a discrepancy?

      Medicare requires A1c at my clinic. It’s a nuisance to go to the lab for a blood draw. Time in range is a much more helpful measurement to me.

      As I’ve noted previously, I have a CGM and depend more on GMI, TIR, StdDev, and COV; I can adjust these for today, the last week, the last month for current status. A1c is in the mix and used, but is too reflective for essential value. For those without CGM, though, it has much more meaning.

      I track my results using an Excel spreadsheet and make adjustments based on that data. I find the A1c a good confirmation that I am making the right adjustments, but I would not be able to make adjustments based on A1c alone.

      While I find the A1C number “useful”, I do not make any changes to my routine based upon my A1C. However, having said that, If my A1C had gone high, I would have taken a closer look at my meal plan, exercise and insulin basals and boluses.
      Luckily, I’ve maintained my exercise and meal plans, and have kept my A1C’s at acceptable levels.
      Day to day data, charts and numbers affect my daily routine very much.

      Having a CGM has removed the benefits from the A1c measurement as a tool to a large extent… Still helpful in terms of knowing whether the CGM is providing accurate data, or not…

      I like to know my reasoning regarding basal rates have been good because it shows in my A1Cs. Also with my bonuses and diet. By staying in touch with my dr with what I’m doing, my A1Cs stay under 7.

      As other have said, my CGM data are far more useful for managing BGs. Also, A1cs underestimate my BGs because of another health condition that makes my RBCs “younger” than they should be. However, my pump supplies provider seems to believe they need to send an A1c number to Medicare so I get it measured anyway when I have my other blood tests done.

      TIR is far more useful. I use the Tandem X2 BIQ and Dexcom 6. Every time I look at my pump (I use it as my receiver) I see if I am “flatlining” – which is good news. Since I have (and prefer) BIQ, if need be I can use temp basal to tweak for the time being. I think that the A1C being just an average isn’t all that informative. Let’s say the goal for A1C is 5. If you bg’s run 5, 5 and 5 your A1C is 5. But if yor bg’s run 0, 5, and 10 your A1C is still 5.

      Overall A1C does not affect how I make changes. Other factors like time in range and standard deviation actually is more helpful.

      I consider A1c an average over 3 months, nothing more. I like to see my average over the last week as an indicator of how any changes I have made are working.
      Time in range and a look at overall patterns are both more important for my daily and long-term management.
      A1c remains a quick question for non-endocrinologists to ask.

      A1c has very little value if you are using a continuous glucose monitor. The cgm gives actual blood glucose values, whereas A1c is a rough estimate with high variability between people. But, A1c is a one test that is easy to do at a clinic. It still has little value.

      I find HA1c useful as a calibration of my other measurements and vice versa.

      A1c “average” is of little help. TIR and standard deviation is far more useful when considering any changes.

      A1C along with time in range are very usefull.

      Time in range based on a range of 70 to 180 is worthless as it is based on the assumption that an A1C of 7.0 is “good control.” Doctors should be honest with their patients and encourage them to achieve an A1C under 5.0 and yes, that is achievable without hypos.

        😮
        That would not be achievable for me. Too many hypos. Hypos kill brain cells.

      Being a T1D for almost 38 years, the A1C was the gold standard until TIR & AGP came on the scene. Interestingly enough, my A1C brings with it constant dissatisfaction & unspoken guilt as opposed to my TIR. I know how hard I work and am very proud of the high 85% I average per 10 day Dexcom session. No complications so I guess I am doing pretty good despite a 6.8 average A1C

      My A1C is never accurate. For over 20 years I’ve been geting a Fructosamine drawn as well and my Endo says that is much more accurate based on my BS readings. That seems to correlate better with my TIR.

        I have never heard of fructosamine. What is that?

      I’m on Dexcom with Tandem CIQ and I’ve about eliminated all Hypos so my latest A1c of 5.4 seems like a Cure to me. Just working on SD and TIR now.

      The a1C is part of it. Time in range, deviation, and yeah elimination of hypoglycemia.

      I said not at all but that is because I use CGM full time and use the average BG on CGM, which is used to generate the GMI (glucose management indicator) as a better indicator.

      Reply to Marsha Miller; My last 3 Endo’s in 3 different states have always ordered Fructosamine Levels when seeing that my A1C didn’t jive with my pump data and sensor info. Fructosamine just measures a 2 week analysis vs 90 days for A1C. I’ve been told I have a certain protein attached to my blood that affects the 90 day test. The 2 week test has always been more accurate for me.

      TIR seems to be more useful

      A1C is nice and all, but TIR is much more valuable to me.

      Because I use a closed loop pump system with CGM, I depend more on the “Time in Range” than A1c. A1cs are averages and if I have a lot of lows and highs, the A1c result is not a measure of control.

      A1C is just an average over 90 days, so it is NOT an accurate way to measure BG control. However, due to inaccuracies in CGM readings, Time in Range (TIR), Standard Deviation (SD) needs to be combined with A1C (since its not derived from CGM technology) to determine accurate measure of control.

      A1C is an indicator of an indicator of blood glucose over time. Just because the only tool doctors have is a sledge hammer doesn’t mean they should use it every time we patients have a screw loose. I look forward to the day when CGM reports completely replace A1C tests for type 1 diabetics.

    How useful is the A1c measurement to you as a tool for assessing your T1D management and making changes to your routine? Cancel reply
