Hey guys,

Does anyone know how to help the pump deliver more insulin automatically?

My daughter was on manual mode for about half a year, and then switched to auto mode. Since then, her blood sugar starts rising very high right after she falls asleep (around 250–280).

She has been using auto mode for 4 months now, but the pump still seems to struggle with handling it.

Yesterday we started giving small boluses right after she falls asleep, and now her sugar stays around 180.

Do you have any ideas on how to “teach” the pump to react better or become smarter in this situation?

I am trying to figure out if my vial of insulin, opened just a week go, went bad or if it's just me. :)

I tried Fiasp for a couple of weeks and it wasn't working so well, so I switched back to Apidra. However, after only 2 days, my infusion set started to get very itchy to the point I had to remove it. It was on my well-padded abs. :D I tried another set on the upper butt, and after 3 days, it's getting itchy too (these are Medtronic extended sets that last 7 days).

To test it out, I injected 4 units out of the vial, and... surprise: it got itchy and warm right away.

Has anyone had something like this happen? Maybe it's just the vial that's gone bad, but I'm starting to wonder if I've become allergic to Apidra. I have a history of anaphylaxis, and according to the nurse at the allergist office, I am "allergic to life" (pretty much everything outdoors!).

Ugh, like having diabetes wasn't hard enough...

I just got this update pending. Has anyone tried it yet? Same description as the problem version to fix connectiviity issues.

Anyone have a good source for an over patch to help keep the extended infusion sets from losing adhesion due to showering/swimming? I haven’t found any that seem to fit the cannula outer housing without interfering with the quick disconnect. Before I was just using the guardian 4 tapes that came with them but now I’m on the Simplera Sync and I don’t have a supply of those any longer.

So gone for an off grid 2 nights away with thw wife.

Checked. Hot tub is fine but effects the glue of the sensor and infusion site. OK ill bring a few spares just in case.

Instantly fall over on arriving ripping my infusion off on the handle of the wheelbarrow to the shepherds hut.

Put my skingrips that I thought would help with the hot tub.

WRONG!

Within minutes it was coming off.

Then the sensor.

Then the infusion site..

I have enough to go in once more. But thinking of putting my next sensor and infusion site at top of arm to keep it out of the water haha.

Anyone got any advice?

Looking to hear both successes and shortcomings of different pump and CGM setups. I've only ever used Dexcom and Omnipod (been on Dexcom close to 10 years, and Omnipod around 4yrs).

I wrote up why I want to switch, what I'm looking for, & who I am below. But even if you don't necessarily have a personalized rec for me, I want to hear YOUR story. I know very little about other systems, and I definitely read here and other T1D related subs, but this gives me the chance to potentially have active back and forth convos around what people say. Thank you!!

Why am I looking to switch?

I tried the G7 when it first became compatible with the O5. I hated it. It has terrible connectivity to the O5, and really bad accuracy issues overall. I switched back tot he G6 immediately. I'm not interested in being a part of Dexcom forcing its customer base to switch to an inferior product just because they sank however many millions of dollars into R&D. I know some people love the G7 and I'm genuinely happy for you, but it didn't work for me at all.

For Omnipod, it's less of a single big thing and more that I've grown increasingly frustrated with their clunky algorithm over time. I can still make it work, but after several convos with my care team, it sounds like there are pumps with algorithms that are much more suited to what I need out of a pump.

Wants & needs out of a new system

• Dealbreaker: both must have iOS apps. I will not go back to carrying multiple devices!
• Dealbreaker: GGM & pump must natively work together. Self made loops are dope AF, don't get me wrong, but I'm looking to put less work, not more, into my diabetes management.
• What I love about the O5: It's tubeless. I know there really isn't another tubeless pump out there, but minimal tubing, pumps that are easily tucked away, etc, is my strong preference.
• What I love about the Dexcom: OK, the thing the G7 had going for it was the 20 min startup and the ability to overlap sensors. Also, I love how small it is.
• I don't need super long wear times. I'm good with my current 3 days on the pump and 10 days on the sensor. I tend to get site irritation if it sits on me longer than that, so eg the G7 15 day holds no appeal for me.

What I've looked at already

Medtronic Minimed Flex + Simplera Sync Sensor

• Pros: Looks sleek, is all built and controlled by Medtronic so no compatibility issues.
• Cons: Not out yet so I'd likely be an early adopter, meaning I get to "help" get rid of all the bugs once it hits the wider market.

Tandem T:slim x2 + Libre 3 Plus

• Pros: I've been strongly leaning towards switching to Libre anyway. It's just that the 3 plus doesn't work with Omnipod 5, so I'd need to switch pumps anyway.
• Cons: the T:slim pump controller thingy is so bulky. I do not like how large it is, it doesn't look like it can be easily tucked inside your clothing.

About me (in case any of this is relevant for suggestions)

• 41 F, diagnosed at age 11
• Decent but not excellent control (story of my life). 6.2 A1C, TIR is 61% (but my range is 70-150)
  • One of the reasons why I'm fed up with O5 is because it keeps me at the 150 border, no matter what settings I adjust (please trust, I've looked into it).
• TDD hovers around 30 units (+/- 5)
• Not insanely active, but I do like to swim and I'm also a huge klutz (which is the biggest concern re: tubing).

Each one failed at 3rd day. I literally fitted a new one just a couple of days ago. I didn't even over-tape it as I had a feeling...

Now to email MT for 5 freakin replacements. I have to email as their online replacement thing is limited to single replacements, so rather than 5 reports I'll just email like I usually do.

Guardian 4 :(

I’m considering switching from Tandem T-slim (with Dexcom G7) to Medtronic 780g and Medtronic’s sensor. This seems to be my doctor’s preference (if I’m switching away from Tandem). What should I know? What’s not in the marketing material?

I googled this and asked AI, but I’m getting mixed answers and I would love to ask people that actually live it. Do y’all enter when you drink something like a low-carb Pure protein shake that only has five carbs? My new pump should hit smartguard mode at midnight. I read that I should enter any carb I eat even if it’s a snack but some say if it’s a lower carb like a protein shake, and my numbers aren’t too high not to enter. Thoughts?

I carry an extra insulin pen and needle tips around in case my infusion site fails - how often would you throw it out and get a new one?

I live in northern Alberta so temps range from -35°C to +35°C

Edit: I’m on Fiasp

I've recently switched to the instinct sensor. I love it. However, the numbers are always wrong. Every night, I go low. It'll tell me my sugar is 52. I'll check it with a traditional meter and it's more like 140. All night the alerts persist no matter how many times I check it and enter the correct number.

I'm putting the sensor on the back of my upper arm. Would it work better in a different location? Has anyone else had this happen?

I have chronic illness and brain fog and I had my training last Tuesday on a really bad flare day, but it was the only day that my trainer could do. It was just so much information and I was there for three hours. We got it all set up and she said that the infusion site would last seven days and the insulin would probably last close to that however it looks like I have about 36 units left in my reservoir.

Could someone point me to somewhere really easy to figure out all of this? I know she sent this big booklet that came with everything and I’ve searched YouTube for videos, but I’m having trouble finding anything official or easy to follow even from another diabetic if nothing official from Medtronics. Basically just how to change everything out and am I going to be notified when the infusion set needs to be switched or the pump or is it just gonna run out in the middle of the night? If it got done on Tuesday afternoon when should I do it? I know this is a lot but if anyone can help me like I’m your child I would appreciate it.
