      I am my own advocate. I read about new devices and always investigate side effects of any new medication before starting. I usually bring up but then have good discussion with Endo before making decisions.

      With my endo, I usually have to ask. With the Diabetes Educator, she'll make the suggestion first. They're both very aware that I'm dependent on insurance covering the majority of the cost.

      I wouldn't say that my T1D healthcare provider OFTEN suggests medications or devices that they think would be beneficial to my diabetes management, but they do SOMETIMES suggest options available to me. (I was privileged to be the first person, in the area that I live, to be offered CSII (Continuous Subcutaneous Insulin Infusion, or pump technology) to help control my diabetes. This was after my endocrinologist attended a diabetes conference in the United States where a former Miss America, Nicole Johnson, was demonstrating a Medtronic/MiniMed insulin pump. He asked her for more information on how these pumps work, mentioning that I had extreme difficulty in controlling my diabetes, with me spending as much time in hospital as I was at home when I was taking multiple daily injections (MDI). On his return to the UK, he offered me the opportunity to 'trial' the pump, which I accepted. This was in 1989.)

      I fell in love with an insulin-dependent Type 2 20 years ago. There’s something terribly romantic about taking Lantus together at the end of the day.

      I never knew of anyone who had diabetes, type 1 or 2 before I was married. I became a T1D after I was married.

      I answered “no.” I don’t think my girlfriend at diabetes children’s camp when I was 13 counts. While I think there would be a lot I would have in common with a partner with T1D, I wouldn’t want that to be what brought us together, and I don’t think it would keep us together.

      went on one date with a T1D. she had been dx'd as a child (I was dx'd at 43) so she was very old school. she ragged on me during the entire date about my menu choices, my carbs estimation for my shot and she lost her mind when I ordered a Corona! punchline is that my sugar was less than 150 when I went to sleep.

      When I was married, diabetes was not in the picture at all. All I knew was an uncle who died in 1929 because he refused injections. I developed LADA in my 40's, followed by my husband with Type 2, then my two daughters who had PCOS and Type 2, then my son with Type 2. Enough.

      I have been married since 1985. My wife Susan does not have either type 1 or 2 diabetes, but rather type 3 diabetes- spouse or mate of someone with T1D...:) She has been my guardian for night lows, though she has rarely had to intervene since I started CGM in 8-2006.

      I think my healthcare providers learn about new medications and devices at about the same time that I do. This wasn't the case when I was first diagnosed, pre-internet. Back then, I always looked forward to seeing my CDE because I knew I'd come away with something to make my life easier/better.

      I had to answer “other” because I just got a new endo after my other one retired so I’ve only met with him once. Too early to discuss new technology or medications.

      Generally, no, my healthcare provider does not suggest new medications or devices. However, it is not often that new meds/devices become available. Most things are dependent upon my quarterly blood tests. Recently, my Endo put me on statin drugs when my bloodwork showed high cholesterol over a six month period. Otherwise, I am usually the one who asks about new devices about which I have heard or read.

      I am on the Dexcom, I’m not on a pump though. I am LADA so I have very high insulin resistance, so I use a lot of insulin & there’s just not a pump that would be efficient for my amount of insulin. I’ve tried to get Afrezza, but every Endoc I bring it up to won’t prescribe it. Even though I bring them evidence that it doesn’t cause lung cancer when you’re not a smoker. So frustrating that we can’t agree on that course of treatment.

      SD is a helpful additional measurement in determining how well the TIR reflects BG control. I monitor both on a routine basis.

      It’s not a measurement that I see that often. But, I know that it’s a good measurement to tell me whether I am staying within my range. If I am going above and below my safe range, my SD will be high. Best to keep the SD low.

      Important enough that it let’s me see rise and fall of random overall BG patterns. However, quite frankly I generally don’t pay all that much attention to it because I have learned to trust the Tandem CIQ w/Dexcom G6 integrated system. My TIR is pretty spot on at ~ 88 to 92%.

      Thank you for this question. Have often questioned A1cs because I have so many lows. Multiple endocrinologists and ophthalmologists and primary care have all convinced me after 3+ years to lower basal rate and some bolus calculations. Last A1c preadjustment was 5.6, too many lows. Next one coming up. I’ll ask endocrinologist’s assistance in calculation SD.

      It’s ‘important’, but I’m already doing the best I can, and as long as it’s reasonable, and I know why things vary, I’m content. Can’t say it’s ‘very important’ because it’s not – I can’t stress over something further that I know I’m already doing my best to keep in control.

      Time in range is much more important and may be replacing the value of an SD measurement.

        TIR “replacing” SD? – insufficient and not fully accurate, I think the common data will show. They are NOT the same, not mutually exclusive. Like saying tire pressure is so much more important than tire tread or roadway condition or steering stabilization … NONE of which replace another (except drunkenness or inebriation, just as gross operator error is 100% more important in prevention or can be held 99% causative in a crash).

      SD woud be important to gauge the response of a true closed loop system. Since current CGM is not true closed loop it’s pretty much irrelevant.
      My SD is lilrly very large because my SG rings like a bell after I get up until I go to bed. Right now, TIR is what I watch. Even that has a large variation 92% to 56% from day to day.

      2 years ago Log in to Reply

        Even when you refer to a true closed-loop is NOT like internally created insulin which goes directly from Islets in Pancreas **and** glucagon directly from the liver’s stores into bloodstream into cells’ glucose/insulin receptors. But we are stuck with subcutaneous skin vascular nature, accounting for the nominal 15-minute delay in achieving insulin’s effect. Not to mention disruptive barriers to immediate and predictable insulin effect of scar tissue or infusion site near large muscle when I gets exercised! So, everything we do AFTER CLOSE-LOOP is perfect is still a long shot away from true pancreatic endocrine activity.

      Vitally important. An SD is a measure of the amount of variation or dispersing of a set of values. A low standard deviation indicates that the values tend to be close to the average, while a high standard deviation indicates that the values all over the map.

      The math formula is usually represented by the Greek letter sigma σ . The goal is to have σ < 3. In other words Average Blood Glucose divided by σ should be less than 3.

      Many analyses attempt to contain variation or dispersions to less than 3 SD. If you go beyond 3, you and your data might be called 3 sigma deviants. I may resemble that remark in some respects. ☜(ˆ▿ˆc)

      I have a strong background in statistics and certainly understand the measure and its importance, in principle, in managing blood glucose. That has not caused me to notice or use it as a metric for assessing my control. My control is limited mainly by my errors. When I don’t make any errors, such as forgetting to bolus until I hear a high alert, or mis-estimating the carb (or fat) content of a meal, my BG is very well controlled. So the source of variation is errors that I’m already working to control, and the actual number seems irrelevant to my decision making.

        Ceolmar (SP??), I commend your thinking and explaining. A tool which doesn’t have immediately percievable cause+effect relationship to our behavior is not as effective on changing it as those that do.
        Interested to see where such discussion might lead, especially in the hands of diabetes educators!

      Up until a few weeks ago, I had no idea what it meant. I read the definition and went, “huh?” Then a lovely CDE explained it to me and I finally “got it.”
      And, while I understand it now, I am still trying to come to terms with how I can use this measure to help me manage my diabetes. Having all this data really doesn’t help if you have no idea what to do with it… I am still in learning mode and will get there, I hope!!!

      I do think it’s important as swinging from highs to lows makes life difficult – it is easy to see your SD on the Dexcom Clarity reports. I have read less than 50 is a goal for most diabetics.

      2 years ago Log in to Reply
      1. Bill Marston

        If you have read that less than 50 is a good target, I think you should be reading better stuff. As others here have said a target of AROUND HALF OF THAT is the ballpark we should all be playing in. I, too, am disappointed at SD of 38 or 42 etc…. despite good A1c and average SGs, etc.

      Without knowing SD, an average Sensor Glucose or Blood Glucose reading (A1C) is limited in determining good control. I am a brittle diabetic and my sugars abruptly rise and fall. My A1C is great (<7 my entire lifetime) and TIR is 85-90%, but my SD is often runs 30-40. I prefer 20-25 SD which means I'm in better control.
