      How well do you understand the details of your health insurance coverage?

      When you change your insulin pump site, do you tend to notice a spike in your blood glucose levels afterward?
      There are certain areas on my body where the insulin is more effective than others.

      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.....

      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.

      Usually the opposite. Fresh insulin sometimes sends me low.

      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.

      One nice thing about a watch for readings is that, while it is normally redundant, you can be separated from your phone. For example, when you are in water.

      I selected “other” because my preference (smart watch, mobile phone, or pump screen) depends on circumstances. Watch for a quick and discrete view; pump if I’m preparing for a profile or activity adjustment or bolus, mobile phone if just a food bolus.

      I’ve been using Omnipod for 5 or 6 years and have only had maybe 4 or 5 times when I got an alarm for no insulin delivery. I assume those were because of the two issues you listed.

      Does an insertion site getting infected count? Never had it happen in 10yrs + pumping, but the site I was using about a week ago swelled and became painfully inflamed deep under the skin after I switched to my next site. Didn’t exactly occlude but didn’t help any with absorption. Worst is that I’ve probably lost that location for good, and after a couple of abdominal surgeries my real estate is getting scarce!

      I was having a lot of alarms about insulin flow being blocked in the previous 2 years. I switched to a different set and no longer get those alarms, probably because I can use many more new sites with these sets. My problem is for the first 6-8 hours after I insert a new set it takes the insulin forever to work. Once the site starts absorbing it’s fine, but I hate going high on set change day.

      I don’t have problems with bent cannulas with the Omnipod. Sometimes, if I see blood on the tape in the area of the insertion, my insulin doesn’t seem to be absorbing properly by day two. The other problems I have had have been with the pods getting knocked off or coming loose after getting wet. Still haven’t found a way to go swimming with the Omnipod. No matter what I use to try and keep it secure, it comes off. Anyway, these have been my problems. Don’t remember which have happened in the last three months. 😬

      I have had a few occlusions, which cleared up when I changed infusion sets. They tend to happen within the last 6 hours of wearing a set. (I change every 2 days.) But my worst problem was a steadily rising blood sugar on an airplane to England. I could not change sets on the plane. I could have used one of the syringes I use to fill the Tandem cartridge to give myself an injection. But I finally had a “lightbulb” moment and theorized maybe my tight seatbelt was keeping insulin from getting through the tubing. I put my pump in my bra so the tubing would not have to go under the seatbelt, and like magic, all was well. I used to fly all the time. So I do not know why it happened this time. But from now on, when I am on long trips in the car or on an airplane, I will make sure the tubing is not under my seatbelt!

      Yes! It seemed to be one whole box of insets, but also happened again. I’m glad you asked this question, could it possibly be scar tissue that is bending the cannulas?

      Never thought of “occlusion” as a concern, something to consider. My problem is with my job I have to climb into attics, crawl in “crawlspaces,” maneuver furniture. Snagged the tubing and pulled out or partially, I’m sure I must have damaged something slithering around, at times I’ve changed the insert the same day I placed because after a job it just hurt (not the cute little “discomfort,” I’d rather have highs than that pain).

      Several times a month by the pump is definitely better than MDIs.

      Just once! First time in years! The cannula was not bent, but I did get an occlusion alarm. I have a lot of scar tissue after 33 years of injections and 22 years on pumps.

      I put yes, but I clicked too fast. I should have said I don’t know. I very often get a message of an occlusion but only when I bolus. I never get occlusions any other time. And to top it off, there is nothing blocking my tubing, so I am not sure why I get those messages. I never have bent cannulas since using tru-steel cannulas. They are the only reason I can use a pump as those flexible cannulas bent so often.

      I was having bent cannula issues recently – but only because my hip clip had lost its ability to stay put on my waistband. The pump trying to go to ground would yank downward on the tiny plastic tube and leave it bent – but only sometimes. No way to tell unless BGs started to rise.
      Issue resolved by going back to a Tslim case. Not my favorite, but you do what you have to.
