FREESTYLE LIBRE 2 UNLOCK CODE

[mum2westiesGill]

Does the freestyle libre 2 reader have an unlock code so that you can use it as a bolus advisor?

 

[Ljc]

I don’t know if it is the same as my old one, CAA1C

 

[mum2westiesGill]

Yes @Ljc that code works on freestyle libre 2. Did you ever use the bolus advisor on your old one?

 

[Ljc]

Yes I’ve set it up , I only use it occasionally. Do you need help.

 

[Lucyr]

The bolus advisor for libre 1 only works with fingerprick blood tests, I don’t know if it’s the same for libre 2. Do you use the test strips that go in the libre?

Hi @mum2westiesGill,

I'm pretty new to this community so maybe I'm not understanding your post/question properly; if so I apologise. I've been type 1 since 1989 and have excellent control of my glucose levels. I was 10 at diagnosis so barely remember not having diabetes.

```
- Blood glucose target range 5-8mmol <------- Correct but 4 - 8mmol would be more accurate

- only do a correction if over 12mmol <---- Also reasonable. I'd say take 1 unit of actrapid (Humolog in your case) to correct 3 mmol of blood glucose. But this will be different for each person and will also depend on how recently you last ate carbs/sugar or took insulin

- if under 8mmol at bedtime have 15 - 20g of carbs with no injection <--- This seems insane to me. If you have your basal dose correct, you should waken up the next day with the same blood sugar level you went to bed with. Maybe 2 or 3 mmol less. You shouldn't need to eat anything to counteract your basal insulin. This makes me wonder how high your glucose levels are on the nights you don't need to take 15 - 20g of carbs onboard. If I was sitting at 8mmol before bed, I would consider taking a corrective unit of actrapid to bring it down a few mmols overnight. Have you discussed this with your diabetic clinic? I would expect 15 - 20g of carbs to increase my blood sugar but about 6mmols. So I would waken up with a BG of around 14 or 15mmol. Then you have the "dawn phenomenon" in the morning which will push it up into the 20's. Have you checked your BG when you waken up? And what about 1 or 2 hours after breakfast? I'd say it could be sky high and really uncomfortable.

REF: https://www.diabetes.co.uk/blood-glucose/dawn-phenomenon.html

Ratios 1:10 ~ for everything <------ Not sure what you mean by this?
```

I would say your solution is to balance your basal dose first. This can be done better if you don't eat anything or take any actrapid insulin within 4 hours of going to bed. Obviously you will need your BG to be within a normal range after that as corrections might be needed and will mess up the testing for the basal dose. Then find the right dose that keeps your BG the same in the morning as it was the night before or as close as possible. You would actually be happy with 8mmol before bed and 5mmol in the morning. This is what all your day time actrapid doses can then be balanced on. In my opinion this is a really important step in having control of your BG. You will then feel so much better every day!

A brilliant course you should look into is the DAFNE course. It will show you everything you need to know about what I am suggesting.

Hope this helps. All said with care!

Welcome to the forum @FlatCarpet

The things you are commenting on are Gill’s signature, rather than part of her question - they are simply approaches she has agreed with her diabetes clinic that work for her, and help to keep her safe.

While I don’t disagree with what you say, everyone with diabetes is different, and in terms of basal insulin on MDI, this can very much be a bit of a ‘Hobson’s Choice’, and if a person finds on balance the best fit basal over the 24 hours means they have a little too much active at night, it is not uncommon for people to aim to retire on a higher BG level to protect against overnight hypos. This was certainly a common strategy in older ‘peakier’ basals.

Insulin ratio refers to the amount of insulin one would take for differing amounts of carbohydrate in meals. These can vary at different mealtimes, or in Gill’s case, be the same for all means and snacks 🙂

1:10 would mean 1 unit for 10g of carbs, 3u for 30g of carbs etc.

Right. I would call that 1:1 ratio, but i suppose that's using the CP ratio method. I guess different people have different way of referring to it. 1:10 seemed very high but I get it now, that's a normal ratio.

Fair enough. My HbA1c has rarely been above 48 mmol in over 30 years. I'm just sharing how I do it, but I do know most approaches. I assumed, based on her post, Gill was looking for ideas on a new way to approach it. The question was referring to a "bolus advisor" after all. I would be thinking morning BG would be higher than Gill would like, based on a combination of taking quite a big corrective glucose intake at night, while already on quite a high BG, and then "dawn phenomenon" bites in the morning.

Just something worth noting Gill, you do it your way

Gill is one of a number of members looking at alternatives following Roche’s decision to discontinue the Accu-Chek Expert smart meter 🙂

Wait... Okay I missed this. Apologies Gill. I thought that was information pertaining to your question.

Just a note on bed time levels and the differences there can be.
Please note this only applies to me or others with the same profile.
My Bg readings fall from midnight to 6am by between 6-7 units daily.
This means I can happily go to bed with out any insulin adjustment if I am showing12 -14 I as I will awake with a reading of 6 at about 7am and will only insulin adjust if above that or conversely have a digestive if below 10.

I have been trying to fine tune my Dash pump but I am looking to swap over from a Libre 1 to a Libre 2 sensor as it has Hi/Lo warnings of both auditable and vibration styles which will give me more confidence to be critical with my tweaking adjustment's.

Remember we are all different what suits me might not suit others. I suffer both night time lows and morning highs [dawn phenomenon].
It's all about BALANCE.

Hope the Libre2 helps @mark king and that you can get a flatter glucose curve overnight. Must be quite worrying seeing such a big drop.

 

[mark king]

Yes Mike but it has become the norm for me and quite regular. But as you say I'm hoping that the Libre 2 will allow me to get tighter with my control while affording the safety net of the alarm.
I do have a follow up question on the L2 however.
I presently use both the reader and my phone to scan read the sensor is it just a simple matter of replacing the L1 with the L2 sensor and scan away with no other pairing necessary?
Thanks

You will need a new reader for the L2 (although I think you can use the L1 reader but will not get alarms). Abbott will send you one. If you want to have the alarms you need to decide which device you are going to use to start the sensor with. i.e. if you want the alarms on the reader then start the sensor with that first, but if you want them on your phone, use that to start the sensor.

 

[mark king]

Cheers Patti I have the new reader and L2 sensor I'm just waiting for the L1 to run its 14 days out and then I'll be swapping over.
Scan first with the new reader if I want it to sound alarms, got it.
I'll then use my phone as I do now for Libreview which I do find useful.

Thanks

Best

I've found, from trial and error, that my Samsung A5 phone is easily disconnected from the L2 alarms by incoming notifications for any other app; then there is only a visual on the top of the screen to tell me the alarms aren't active. So my default position is to start the reader first, use that predominantly for the alarms only, but use the phone and app for the "management". Then the Libreview gets as much data as I bother to populate it with, including odd notes documenting something unusual - which I'm finding helpful as "memory joggers".
I had tried suppressing all other app notifications, but that wasn't very helpful and still the alarm would disconnect for unknown reasons. In due course I'll need to replace the phone and perhaps a younger model with the latest android software will be better.
