MySugr app and carbs/insulin ratio set up

[mum2westiesGill]

Carbs/Insulin ratio which it says on MySugr app but I've always thought it's insulin/carbs ratio (matching insulin to carbs) or doesn't it really matter?

My insulin to carb ratio is 1:10 (1u insulin to every 10g of carbs)

I've been doubting myself again so I've posted some pics just to check that I've got my MySugr insulin to carb ratio set up correctly. Does anyone know if I have got it set up correctly?

Just a thought… my insulin to carbs varies during the day 1:10 in the morning, but 1:20 for dinner and tea . Yours might vary as well.

Yes, that looks right. MySugr uses 'carb portions' where one 'carb
portion' is 10g of carb. so a Mysugr ratio of 1 unit of insulin to 1 carb portion is the same as saying 1:10 carb ratio where you’re counting the carbs in grammes.

Thanks @Robin. If I wanted to change very slightly to 1:9 or 1 unit of insulin to every 9g of carbs looking at the pictures - in the box where it says carbs/insulin ratio and I've entered 1.0 would I change that to 9.0? Also where it says time-dependant setting and I've set it to 1.0 units would I leave that as 1.0 units?

It says “how many units of insulin do you inject for one carb portion”. You’ve put 1. So if a carb portion is 10g carbs then your current setting is 1 unit of insulin per 10g carbs. If you then change the 1 to 9 you are telling it that you enter 9 units of insulin per 10g carbs 😱😱
Unfortunately it’s doing it the wrong way round - I think you need to enter 1.11 units per carb portion which would equate to 1 unit per 9g carbs, if I’ve done my sums right 🙄

I keep forgetting that we are on a pump which can do much tinier changes than would be possible with injections so I don’t know if this is even possible/worth the effort if you are injecting?
Have you spoken to your DSN? We aren’t really supposed to tell you how much to change things by, best to run any ideas by her first if you aren’t sure yourself. Wait a few days too and see if you get the same things happening every day before you start fiddling with settings, you don’t want to have to change it all back again if it was just a one-off blip.

I know a few people have pens that do .5 insulin. Mine is just in 1 units.

I’m intrigued. My mySugr doesn’t look anything like that! Personally I think units:carbs is much easier to calculate!

Sally I am pretty sure it would be 1:0.9 ie 1 unit of insulin to 0.9 of a Carb Portion or 9g carbs not 10g...... not 1:1.1 as you have suggested which would be 1 unit of insulin to 11g carbs.
ie 9g carbs would be 0.9 X 10g carbs. Maybe that doesn't make it any clearer...
If you look at it this way, you are intending to use more insulin for the same amount of carbs so you need to reduce the carb portion fraction.

 

[rebrascora]

@mum2westiesGill I think you would need to adjust one of the time periods below the insulin carb ratio to show maybe 12noon-4pm would be the timescale for that 1:0.9 ratio and the rest of the time remaining at 1:1

I think it’s the insulin Sally's adjusted, by devious maths, not the carb portion. It depends whicn way round the Mysugr app lets you do it. If you always have to have a complete carb portion, ie you can’t adjust it down from 1CP to 0.9, then you have to adjust the insulin amount, which would need to go up, and equates to 11.1 units of insulin to 1 carb portion.

 

[Sally71]

But it says “how many units of insulin do you inject per carb portion”. One carb portion is 10g and that is fixed, it is asking you to change the insulin units in the box. And you want to increase the insulin, not reduce it.
It would be much easier if it was asking how many carbs per unit of insulin, then you could just change it to 9!

I don't use MySugr but the app that I sometimes use will take fractions of CPs ..... but I get what you are saying now. It is a backwards way of doing it and it looks like it might be an old format which has now been updated and improved if @JJay's version is anything to go by. I would guess that Gill needs to upgrade the app..... Making it all a bit more complicated.

There is nothing on my Google playstore to say it needs upgrading

Iphone. I can see that the look of the app might vary between the two versions, but it seems very odd that the method of calculation is different

I'm on Android. You might be better at wording it than me but maybe you could contact them and ask them why the method of calculation is different 🙂🙂

 

[Lucyr]

You can choose whether you use carb portions or grams. I personally think grams is easier to understand and to change from 1:10g to 1:9g but it’s up to you what you use.

 

[Lucyr]

And here’s the two ways I can enter my ratio depending on whether I want to use grams of carbs or carb portions (these aren’t my real ratios, I haven’t used mySugr for bolus advice in ages).

 

[JJay]

Thanks. I honestly hadn't noticed that! Mind you, I've not thought of carbs in 10 gram portions/exchanges since I went on basal/bolus, which must be getting on for 20 years ago now.

I totally agree about using grams - I find it easy enough to divide by 6, 7, 8 whatever in my head, but a nightmare the other way round! (I know I could manage without the bolus calculator quite easily if I wanted, but it's there so I use it!)

It seems we both have the choice, Gill - I'd not noticed that before. Personally I find the "grams per unit" method a lot more straightforward (and easy enough to do in my head if I happen not to have my phone handy), but do what feels right for you!
